When considering employment in Japan, many people wonder, “Can I work using only English?”
In an increasingly globalized Japan, opportunities to work solely in English are steadily expanding. However, certain conditions and preparations are necessary.
This article explains in detail the realistic possibilities of working exclusively in English and the preparations required to do so.
1. Current State of Japanese Companies Where You Can Work in English Only

Japan’s business environment is rapidly globalizing, and environments where you can work exclusively in English are steadily expanding.
Particularly in foreign-affiliated companies and Japanese companies with international operations, the movement to adopt English as the official language is accelerating.
This trend is expected to continue expanding from two perspectives: strengthening Japanese companies’ international competitiveness and developing global talent.
Reality and Examples of Companies Adopting English as Official Language
The adoption of English as an official language in Japanese companies began in earnest in the 2010s.
Rakuten Group pioneered this movement, declaring English as their official language in 2010 and establishing a system where all internal meetings and document creation are conducted in English.
The company actively promotes employees’ English proficiency by setting TOEIC scores as promotion requirements.
Fast Retailing (UNIQLO) has also been gradually promoting English as their official language since 2012, and by focusing on developing global talent, they have successfully accelerated their overseas expansion.
Other major companies such as Honda, Sharp, and Bridgestone have standardized English usage, particularly in research and development departments, building a foundation for global communication.

English-Only Work Environments in Japan
In English-only work environments, meetings and emails are basically all conducted in English, and internal documents and presentation materials are also primarily in English.
However, rather than being completely English-only, many environments function as bilingual environments with both Japanese and English.
Organizational culture features more flat organizational structures and environments where employees of diverse nationalities coexist.
Additionally, global standard work styles are introduced, collaboration with overseas locations occurs daily, and there are abundant opportunities to participate in global projects.
Advantages and Disadvantages of Companies Emphasizing English Proficiency
Companies that adopt English as their official language have various advantages and disadvantages.
Advantages
Business advantages
Quick access to global markets is possible, and international competitiveness improves as recruiting overseas talent becomes easier.
Employee career benefits
International career opportunities increase, and continuous improvement of English skills and acquisition of a global perspective can be expected.
Disadvantages
Organizational operation disadvantages
Reduced communication efficiency, initial productivity decline, and the risk of internal division have been pointed out.
Human resource challenges
Potential limitations in recruiting talented Japanese speakers, increased English training costs, and increased employee stress are also issues.
Considering these circumstances, many companies adopt gradual English introduction and flexible language policies by department, tending to build hybrid environments of Japanese and English rather than completely English-only environments.
2. Professions Where You Can Work in English Only and Required Skills

In increasingly globalized Japan, professions where you can work exclusively in English are steadily growing.
Particularly in foreign-affiliated companies, the IT industry, research and development departments, and the tourism industry, environments using English as the primary language are being established.
To succeed in these professions, comprehensive abilities including advanced English skills, specialized knowledge, business skills, and cross-cultural understanding are required.
Examples of English Usage in the IT and Technology Industries
In the IT industry, environments exclusively using English are established primarily for software engineers and project managers.
Software engineers need programming skills and technical writing abilities along with experience collaborating with overseas teams, while project managers require knowledge of agile development, cross-cultural management, and remote team management skills, with experience in global development environments being highly valued.
English Usage in Education and Research Fields

With the increase in inbound demand, opportunities to use English as the primary language in the tourism industry are rapidly growing.
Hotel staff positions include front desk operations, concierge services, and accommodation facility management, while tourism-related positions include tour guides, travel coordinators, and inbound sales representatives.
These positions require both basic customer service skills and cross-cultural understanding abilities, complaint handling skills, and knowledge of local tourism information, requiring both language skills and specialized knowledge.
3. Conditions Necessary for English-Only Jobs

Working exclusively in English requires not just language skills but comprehensive business skills and practical experience.
The conditions companies require are diverse, with a tendency to emphasize practical experience and communication abilities. Meeting these conditions allows for more career opportunities.
