Your 30s are a pivotal time when technical skill and career direction intersect. Many engineers in this stage find themselves wondering how their skills are valued by the market — and whether their current salary as an IT engineer is where it should be.
Looking at government statistical data — including the MHLW “Basic Survey on Wage Structure” — salaries for information and communications industry workers in their 30s are spread across a wide range depending on role, company size, and region, making it difficult to gauge your own position from a simple average alone.
This article draws on government statistics to break down the real salary landscape for IT engineers in their 30s by role, company size, and skill set.
We also cover concrete methods for increasing your income and the career paths available to you — so read on as a reference for assessing where you stand and thinking through your next move.
- The overall salary range for IT engineers in their 30s, and why the numbers vary so widely

1. Average Salaries for IT Engineers in Their 30s — What Government Statistics Actually Show
When discussing salaries for IT engineers in their 30s, the first thing to check is reliable public data.
Figures published by private job services vary depending on who is included and how the data is aggregated — which is why government statistics are the right baseline to establish first.
Here, we use official MHLW surveys to map out a realistic starting point for understanding where 30-something engineers actually stand.
MHLW Data Shows the Average Salary for IT Engineers in Their 30s Is in the ¥5–5.7 Million Range
According to the MHLW “Basic Survey on Wage Structure (2023),” scheduled monthly wages in the information and communications industry are approximately ¥330,000–¥340,000 for workers aged 30–34, and ¥360,000–¥380,000 for those aged 35–39.
Adding annual bonuses and special payments, this translates to roughly ¥5.0–5.3 million for the 30–34 age group and ¥5.4–5.7 million for the 35–39 group.
These figures cover the information and communications industry as a whole — and it’s worth noting that the mix of roles (PMs, SEs, infrastructure engineers, etc.), employment types, and regional differences all influence the average.

Why You Can’t Directly Compare Your Salary to the Government’s “Average” for 30-Something IT Engineers
The figures in the MHLW “Basic Survey on Wage Structure (2023)” represent an average across the entire information and communications industry — covering everyone from PMs and senior SEs to development and testing engineers at companies ranging from large enterprises to small firms.
This means that even within the broad category of “30-something information and communications workers,” actual salaries are spread widely depending on employment type, role, company size, and region.
The nature of “averages” is particularly important here. High-earning roles like IT consultants and PM-level professionals pull the overall average up — which means a simple comparison between your salary and the average can create a distorted picture.
Narrowing your comparison down across three axes — role, company size, and region — is what gives you an accurate read on where you actually stand.

Salary Growth Patterns Shift Between Early and Late 30s
Looking at MHLW statistics in five-year increments, there is a clear difference in salary levels between the 30–34 and 35–39 age groups.
Ages 30–34: Technical Skill Is the Primary Driver of Salary
In the early 30s, building technical skills — programming, infrastructure design, and the like — is the primary factor determining salary level.
Market demand for the languages and frameworks you know, along with the breadth of project phases you can handle (development, testing, design, etc.), are the main things driving your salary at this stage.
Ages 35–39: Management and Upstream Involvement Become the Dividing Line
By the late 30s, the salary equation expands: in addition to technical skill, how much you’re involved in project leadership, team management, and requirements definition becomes a major differentiating factor.
Whether you’ve accumulated upstream experience by this stage is what separates engineers who earn hundreds of thousands — or over a million yen — more than peers at the same age and general category.
Thinking consciously about whether your career is in a “sharpening skills” phase or a “transitioning to management” phase helps you assess your current salary position more accurately.

2. How Salaries for 30-Something IT Engineers Vary by Role
“IT engineer” is an extraordinarily broad category — and even among people in their 30s, salary levels differ dramatically depending on the actual role.
Whether you work in SES, contract development, or in-house development — or whether you’re a consultant or freelancer — can shift your salary range by hundreds of thousands of yen.
Understanding how the market values your specific role is the first step toward increasing your income.
High-Earning Roles for 30-Something IT Engineers ①: Project Manager / IT Consultant
Project managers (PMs) and IT consultants consistently occupy the higher end of the salary spectrum among 30-something engineer roles.
The METI document “Trends in IT Human Resources in Japan” notes that project management professionals and IT consultants who handle upstream processes are in chronic short supply — with demand outpacing supply in ways that push compensation higher.
What underpins this salary level is the “multiplication” of technical skill and business understanding. Requirements definition and system design, combined with client negotiation, budget and schedule management, and team leadership — it’s the combination of these skills that gets evaluated and rewarded.
A career shift toward PM or PL roles is one of the most direct routes to a meaningful salary increase in your 30s.

High-Earning Roles for 30-Something IT Engineers ②: SES and Contract Development — the Typical Range Is ¥4.5–5.5 Million
For engineers in their 30s working primarily in SES (System Engineering Services) or contract development, cross-referencing MHLW “Basic Survey on Wage Structure (2023)” data for smaller companies in the information and communications industry places the central salary range at ¥4.5–5.5 million.
This salary level is shaped by two key factors: the structure of how pay is determined, and which project phases you’re responsible for.
How Pay Works: Contract Rate × Company Return Rate
In the SES industry, your salary is determined by the client billing rate and the company’s return rate — the share of that rate that flows through to you.
Even if the monthly contract rate is high, a low company return rate means your take-home salary won’t grow much — and improving your technical skills alone hits a ceiling. Moving to a company with a higher return rate, or getting onto higher-value contracts, are the realistic levers for raising income.
The MHLW “Basic Survey on Wage Structure (2023)” company-size data shows that in the information and communications industry, companies with 10–99 employees tend to have statistically lower wage levels compared to large companies with 1,000+ employees — confirming the structural difficulty of salary growth in small SES firms.
Source: MHLW “Basic Survey on Wage Structure (2023)”
The Salary Gap Between Upstream and Downstream Engineers
Even within the same SES environment, engineers handling upstream phases — requirements definition, high-level design — command higher contract rates than those focused on manufacturing and unit testing.
Whether your career has shifted toward upstream work by your 30s is what determines the salary gap within SES.
High-Earning Roles for 30-Something IT Engineers ③: In-House and Web Development — Skill Stack Makes the Difference
Engineers working at companies with their own products (commonly called web-native or product companies) tend to see salary variation driven significantly by the programming languages and frameworks they’re proficient in.
The MHLW “Basic Survey on Wage Structure (2023)” data broken down by company size and industry also suggests that information and communications companies with their own services tend to have higher wage levels than those focused primarily on contract work.
The Salary Gap Between Modern and Legacy Languages
Engineers who work with modern languages like Go or TypeScript tend to receive higher salary offers, reflecting the growing demand for these skills.
By contrast, engineers whose skills are limited to specific legacy technologies like COBOL or VBA often face a lower salary ceiling, given the narrower demand for those tools.
The combination of market scarcity and demand is what creates the salary gap tied to tech stack. METI’s “Trends in IT Human Resources in Japan” also notes that demand for professionals in advanced areas like cloud, AI, and data analytics is particularly high — and that scarcity in these areas is pushing up compensation for those who hold these skills.

High-Earning Roles for 30-Something IT Engineers ④: Freelancing Can Put High Income in Range
IT engineers who leave full-time employment to work as freelancers have contract rates that flow directly into income — meaning that with the right skills and track record, it’s possible to earn significantly more than as an employee.
The expansion of IT talent demand documented in METI’s “Trends in IT Human Resources in Japan” is also creating a sustained pipeline of high-value contracts in the freelance market.
Be Honest About the Risks of Going Freelance
At the same time, freelancing carries risks that employment doesn’t: higher social insurance costs you pay yourself, the risk of gaps between contracts, and the absence of paid leave and retirement benefits.
When you compare on a take-home basis, the gap between freelancing and employment is sometimes smaller than the headline income difference suggests. A clear-eyed comparison of the benefits and risks is important before making the move.
3. How Company Size and Region Affect Salaries for 30-Something IT Engineers
Salary is shaped not just by individual skill and role, but significantly by the size of the company you work for and where it’s located.
Public data shows that even with equivalent technical skills and the same role, the difference between a large company and a small one — or between Tokyo and a regional city — can amount to hundreds of thousands, or nearly ¥2 million, in annual salary.
Understanding how your choice of employer and location affects your salary is important context for any career decision.
Large Companies (1,000+ Employees) Tend to Pay 30-Something IT Engineers Significantly More
The MHLW “Basic Survey on Wage Structure (2023)” company-size breakdown shows that in the information and communications industry, companies with 1,000 or more employees have clearly higher wage levels for workers in their 30s compared to companies with fewer than 100 employees.
Larger companies tend to have greater profitability and more capacity to invest in people — which flows directly into salary levels. This wage gap is also deeply intertwined with the IT industry’s distinctive multi-layer subcontracting structure.
Source: MHLW “Basic Survey on Wage Structure (2023)”
The Salary Gap Between Prime Contractors and Second- or Third-Tier Subcontractors
The IT industry’s multi-layer subcontracting structure is directly linked to the salary gap by company size.
Large SIers and vendors that contract directly with clients as prime contractors retain most of the project margin in-house — which means they can afford to pass a higher share of it through to their engineers.
At second- and third-tier subcontractors, intermediate margins eat into what reaches the engineer — so even doing equivalent work, take-home salary is structurally more constrained.
Small Companies and Startups Involve a Trade-Off Between Salary and Growth Opportunity for 30-Something Engineers
While small companies and startups often pay less than large enterprises, they frequently offer advantages that money can’t directly measure: greater autonomy, faster responsibility growth, and a richer environment for technical development.
How to Evaluate a Startup Decision in Your 30s
If you’re prioritizing long-term skill development and career building over near-term income, joining a startup can be a thoroughly rational choice.
That said, doing the due diligence upfront — verifying that stock options are genuinely achievable, understanding the company’s growth stage (seed, Series A, etc.), and confirming that the technologies you’d use are marketable — is important for managing your downside risk.
Tokyo vs. Regional Cities: A Gap of ¥1–2 Million in Annual Salary for 30-Something IT Engineers
The MHLW “Basic Survey on Wage Structure (2023)” regional breakdown shows that even in the information and communications industry, wage gaps exist between the greater Tokyo area and regional cities.
For IT engineers, Tokyo-area salaries are shown to run ¥1–2 million higher than their regional equivalents in many cases.
Full Remote Work: Earning Tokyo-Level Pay While Living Regionally
Recent changes to how people work, combined with the spread of remote work, have made it increasingly viable to live in a regional city while participating in Tokyo-based companies and projects.
Earning a salary comparable to urban rates while living where costs are lower is a genuinely practical strategy for 30-something engineers looking to maximize their take-home income.
That said, it’s important to keep in mind that fully remote positions are competitive, and typically require a solid level of skills and track record to access.
4. How 30-Something IT Engineers Can Increase Their Salary
Once you have a clear sense of the salary landscape, the next important question is: “What can I actually do to raise my income?”
Your 30s are a time when technical maturity is setting in and management experience is beginning to accumulate — which opens up multiple realistic paths to a higher salary. Here’s a breakdown of the most effective approaches, assessed for both speed of impact and sustainability.
For 30-Something IT Engineers, Shifting Into Upstream Processes or Management Is the Fastest Route to a Higher Salary
The approach with the greatest sustained impact on income is a career shift into upstream work or management.
Steps to Making the Move Into PM or PL — and the Skills You’ll Need
Transitioning into a project manager (PM) or project leader (PL) role requires more than technical skill — you’ll need experience in scope management, risk management, and coordination and communication with stakeholders.
Taking on the lead role for a small internal project and building a track record from there is the realistic starting path.
How Salary Curves Differ: Specialist vs. Management Routes
Technical specialists tend to see salary growth proportional to how deep and rare their expertise becomes — but the ceiling arrives relatively earlier.
By contrast, those who move into management tend to see the most significant salary increases in mid-career (late 30s to 40s) — and for anyone who wants to keep growing their income over the long term, the management route tends to have the advantage.
Certifications (PMP, Advanced IT Engineer, etc.) Can Add Hundreds of Thousands to Annual Salary for 30-Something Engineers
Earning certifications is an efficient way to make your skills visible and increase your market value.
For engineers in their 30s, two main streams of certification are particularly useful for increasing salary: international project management qualifications and Japanese national IT certifications.
The Salary Premium of PMP Certification
According to PMI’s (Project Management Institute) “Project Management Salary Survey,” PMP holders earn a median salary premium of approximately 9–16% compared to non-holders.
As internationally recognized proof of project management competence, it functions effectively in hiring evaluations and salary negotiations.
When to Pursue It and Where It Applies
PMP requires approximately 3–5 years of PM experience, making it well-aligned with where many engineers are in their 30s.
It’s particularly effective when applying to major SIers, foreign IT companies, or consulting firms, and when negotiating an internal move into a PM role.

How the Market Views IPA Advanced IT Certifications
The advanced-level certifications offered by Japan’s Information-technology Promotion Agency (IPA) — including Applied Information Technology Engineer, Systems Architect, and Network Specialist — are frequently referenced in hiring and salary reviews as objective proof of technical competence.
For large SIers and public sector system projects in particular, holding these certifications can directly influence which projects you’re assigned to and how you’re evaluated.
Which Exam to Target by Role
For those targeting upstream processes and architecture design, the Systems Architect exam is the most recognized. For infrastructure and network roles, the Network Specialist exam. For security roles, the Registered Information Security Specialist exam — each is well regarded in its respective domain.
Adopting a Modern Tech Stack (Go, TypeScript, Cloud, etc.) Raises Both Salary and Market Value for 30-Something Engineers
The technologies you choose to work with directly affect your salary. Skills with high market demand and relatively few practitioners command higher offers in hiring, as competition for those engineers intensifies.
Which Technologies 30-Something Engineers Should Prioritize Learning
METI’s “Trends in IT Human Resources in Japan” notes that as DX accelerates, the shortage of talent in cloud, AI, and data analytics is becoming acute — and demand for professionals in these areas is especially strong.
Specifically, modern languages like Go and TypeScript; cloud platforms like AWS, GCP, and Azure; container technologies like Kubernetes; and skills in ML engineering and data infrastructure are all effective for increasing a 30-something engineer’s market value.
Rather than discarding your existing skills from scratch, the most practical approach is to “add” modern elements on top of your existing technical foundation.

For 30-Something IT Engineers, Changing Jobs Is the Fastest Way to Increase Salary
Among all the approaches to raising income, changing jobs is the one most likely to produce results in the shortest time.
Internal raises within a company are typically limited to a few tens of thousands of yen per year — while a job change, negotiated well, can produce a substantial improvement in a single step.
Data on Salary Increases Through Job Changes
According to the MHLW “FY2023 Employment Mobility Survey,” approximately 34% of job changers across all industries received higher wages than at their previous employer — with the proportion tending to be relatively higher for professional and technical workers (the category that includes IT engineers).
The longer you stay at the same company, the less flexibility the internal pay structure tends to have — and the gap between your internal valuation and what the job market would offer tends to widen over time.
Source: MHLW “FY2023 Employment Mobility Survey”
Preparing for a Successful Salary Negotiation When You Change Jobs
To maximize salary gains when changing jobs, it’s essential to research market rates in advance and clearly organize your skills and achievements.
Being able to show numerically “where I sit relative to industry market rates” — and running processes at multiple companies simultaneously — is what gives you leverage in negotiations.

5. Career Paths for 30-Something IT Engineers Targeting ¥10 Million
The ¥10 million mark is a symbolic goal for engineers in their 30s. It’s not an unrealistic number — with the right career direction and the right actions, it can come into view in the late 30s.
Here’s a concrete look at the career paths most likely to get you there.
Roles Most Likely to Reach ¥10 Million for 30-Something Engineers ①: IT Consultant / Pre-Sales Engineer
IT consultants and pre-sales engineers are roles that demand a high level of both technical knowledge and business proposal skills.
Their scarcity means that offers of ¥10 million or more are relatively more common in these roles, even for candidates in their late 30s.
Route Into IT Consulting
Transitioning to a Consulting Firm After SE / PM Experience
The typical path into IT consulting is to accumulate system development and implementation experience, then move to a consulting firm.
Major IT consulting firms have strong mid-career hiring demand in the 30s age group, and professionals with PM and SE experience tend to be evaluated favorably.
Route Into Pre-Sales Engineering
A Role Where Technical Skill and Proposal Ability Are Both Valued
Pre-sales engineers handle technical proposal activities at vendors and SaaS companies — with communication skills and technical ability together forming the core of how they’re evaluated.
It’s a career path that 30-something developers with hands-on experience can enter by building up client-facing and presentation skills alongside their technical background.

Roles Most Likely to Reach ¥10 Million for 30-Something Engineers ②: Moving to a Major SIer or Foreign IT Company
For engineers in their 30s, changing jobs to a major domestic SIer or foreign IT company is a powerful option for a significant salary increase.
Knowing the requirements and the market context clearly before entering the job search increases the chances of success.
What Foreign IT Companies Require
Balancing Technical Skills and English Proficiency
Foreign IT companies require business-level English — including the ability to read documentation and participate in meetings in English — alongside technical skills.
That said, not every role demands the highest level of English — development positions in particular may be accessible to those whose English is primarily reading and writing focused.
DX Creating Growing Demand for 30-Something IT Professionals
The Structural Talent Shortage Shown in METI Data
METI’s “Trends in IT Human Resources in Japan” documents growing demand for advanced IT talent driven by DX — with architect, PM, and consultant-level professionals in their 30s being particularly undersupplied.
This talent shortage is raising the market value of 30-something engineers.
Source: METI “Trends in IT Human Resources in Japan”
Roles Most Likely to Reach ¥10 Million for 30-Something Engineers ③: Freelancing Is a Real Path, But Requires Preparation
As a freelancer, consistently landing contracts at ¥800,000–¥1,000,000 or more per month puts ¥10 million annual income within realistic reach.
But sustaining a flow of high-value contracts requires meeting certain conditions.
What It Takes to Land High-Value Contracts
Securing premium contracts requires a proven track record and portfolio in your specialist area, experience on large-scale projects or in upstream phases, and established channels for finding work — whether through agent networks or professional relationships.
The Typical Profile of a Freelance Engineer Earning ¥10 Million
Most freelance engineers who have actually achieved ¥10 million or more have 10+ years in the IT industry and a defined strength in at least one of: cloud architecture, large-scale system design, or project management.
The typical trajectory is: build experience at a large company or in upstream projects as an employee, then use that track record to command high-value contracts after going independent.
6. Common Questions About Salaries for 30-Something IT Engineers
Here are answers to questions that engineers in their 30s commonly have about salary.
Is a Salary Below ¥5 Million Low for an IT Engineer in Their 30s?
The honest answer is: it depends heavily on role, employment type, and company size. Looking at the MHLW “Basic Survey on Wage Structure (2023)” data for the information and communications industry, the average annual salary for the 30–34 age group is in the ¥5.0–5.3 million range.
So below ¥5 million is technically below the statistical average — but it’s far from extremely low.
In smaller SES companies or regional firms, annual salaries of ¥4.5–5 million for engineers in their 30s are not uncommon.
That said, many people in this range find that their salary increases when they enter the job market. If you’re wondering whether your pay is appropriate, checking your position within the industry through a recruiter or career advisor is a useful step.
Source: MHLW “Basic Survey on Wage Structure (2023)”
What Salary Can I Expect if I Change Careers Into IT Engineering in My 30s With No Experience?
Immediately after switching careers into IT in your 30s without prior experience, you’re starting from a point where IT skills haven’t yet been fully developed — which means your salary will be lower than experienced engineers at the same age.
MHLW “Basic Survey on Wage Structure (2023)” data on short-tenure workers in the information and communications industry shows that wages in the early stages of IT work experience tend to land close to those of people in their early 20s, regardless of age.
That said, if prior career experience (sales, consulting, finance, etc.) is valued in combination with IT skills, some people receive a meaningful starting evaluation from day one.
How quickly individuals catch up varies — but after 3–5 years of hands-on IT experience, reaching the ¥5 million range is a common trajectory, and how far it goes from there depends significantly on technical growth and career direction.
Source: MHLW “Basic Survey on Wage Structure (2023)”
For 30-Something IT Engineers, Which Is More Effective for Raising Salary: Internal Negotiation or Changing Jobs?
In terms of speed and the size of the potential increase, changing jobs has the advantage. Internal raises are constrained by the company’s HR system — and in most cases, each individual raise is limited to a few tens of thousands of yen.
By contrast, the MHLW “FY2023 Employment Mobility Survey” shows that the proportion of job changers whose wages increased is high among professional and technical workers — confirming that personal technical skills and experience tend to translate into salary improvements when tested in the market.
For internal negotiations, effective tools include: preparing market rate data, quantifying your contributions and outcomes, and using outside offers as leverage in the conversation.
The most effective sequence is: first check your external market value, then enter the internal negotiation from a position of informed confidence.

7. Summary — Salary Landscape for 30-Something IT Engineers, and the First Step Toward Earning More
Government statistics place the baseline salary for 30-something IT engineers in the ¥5–5.7 million range — but actual salaries span a wide spectrum from ¥4 million to well over ¥10 million, depending on role, company size, and skills.
Multiple paths exist for increasing income: moving into upstream processes, earning certifications, updating your tech stack, and changing jobs.
Getting a clear picture of where you stand right now — and then checking your market value — is what makes the next step possible.
