According to the Ministry of Economy, Trade and Industry’s “IT Human Resources Supply and Demand Survey,” Japan’s IT industry continues to face a serious talent shortage, with a projected deficit of approximately 790,000 IT professionals by 2030. As a result, software engineers are expected to remain in high demand.
This article provides a detailed explanation of the knowledge, skills, and specific steps needed to become a software engineer in Japan.
1. Current State of the Software Engineering Market in Japan

Japan’s IT talent market is undergoing a major transformation due to technological evolution and accelerating digital transformation (DX). While the demand for software engineers is rapidly increasing and the talent shortage is becoming more severe, career opportunities are expanding.
Severe Talent Shortage and Growing Demand
Japan’s software engineering market faces an unprecedented talent shortage. According to the Ministry of Economy, Trade and Industry’s “IT Human Resources Supply and Demand Survey,” there is expected to be a shortage of up to 790,000 IT professionals by 2030.
This serious situation is primarily driven by increased demand due to DX acceleration and ongoing maintenance and operation needs for existing systems. Furthermore, the declining working population due to the aging society and delays in IT education systems are exacerbating the talent shortage.
Increasing Trend in Foreign Engineer Recruitment
Many Japanese companies are actively recruiting foreign engineers to address the talent shortage.
According to a Ministry of Health, Labour and Welfare survey, as of October 2023, the number reached 85,000, showing a significant increase of 12.4% compared to the previous year and roughly tripling over the past decade (this trend is expected to continue).
This trend is driven by efforts to diversify talent with global expansion in mind and an increase in companies adopting English as their official internal language. The introduction of preferential immigration status through the Highly Skilled Professional Points System has also encouraged the recruitment of foreign IT professionals.
Average Annual Income and Future Prospects
The market value of software engineers is steadily rising. Here are some examples
Software Engineer Salary Model
- Entry-level (New graduates): Monthly salary 220,000-250,000 yen (Annual income 3-4 million yen)
- 3-5 years experience: Annual income 4-6 million yen
- 5+ years experience: Annual income 6-8 million yen or more
- Senior engineers/architects: Annual income can often reach 8-12 million yen or more
Factors indicating market potential include the spread of cloud computing, rapid growth in AI and machine learning fields, increased software demand due to IoT device proliferation, and growing security-related demands.
Demand is particularly high in cloud infrastructure, data science, mobile application development, and cybersecurity fields.
