Why Japan’s Tech Companies Are Racing for International Backend Engineers

Data shows Japan’s population is declining and aging, leading to a serious labor shortage; 52.6% of companies report lacking needed staff and bankruptcy events linked to employee gaps have risen sharply.

For international developers dreaming of moving to Japan, this creates a rare opportunity, though many misconceptions persist about immigration policies, language requirements, and job availability.

Is the labor shortage a good thing?

Historically, Japan’s labor policies focused on lifelong employment with long hours and stagnant wages, which once drove economic growth but now contribute to stagnation and mild deflation.

Companies are now shifting to attract experienced workers with higher wages, better work‑life balance, diversity, and openness to international talent.

Japan needs more immigrants

Foreign worker numbers have quadrupled over the past 15 years, exceeding 2 million by October 2023, yet experts predict a shortfall of 1 million foreign workers by 2040 to meet a 1.24% annual growth target.

Talent‑recruiting experts remain optimistic about Japan’s ability to attract international professionals.

Technical talent in demand

Technology sectors feel the impact most acutely; 52.6% of Japanese companies struggle to find and retain staff, rising to 77% among IT firms, with the gap widening from 65.7% in 2021 to 73.1% in 2022.

Key roles include backend development, Python programming, and AI/ML expertise, all seen as essential for the country’s digital transformation (DX) initiatives.

Soft skills

Beyond technical ability, Japanese firms prioritize communication, leadership, people‑management, and Scrum experience, often valuing these over pure coding skills.

Required abilities

Backend development is the most common English‑language position, with Python being both popular and in short supply. AI and machine‑learning skills are especially coveted as Japan views them as solutions to demographic challenges.

Quality Assurance

DevOps

While many roles do not require Japanese language proficiency, fluency (e.g., N2 level) can significantly enhance career progression.

Cross‑border development teams

Companies such as Cybozu, MoneyForward, and Givery are building international engineering teams or moving toward English‑only workplaces, a trend expected to accelerate.

These initiatives can give Japan a competitive edge, though cultural integration challenges remain.

Conclusion

The labor shortage threatens Japan’s long‑term welfare, making immigration and skilled foreign talent a natural and urgent solution, especially for tech companies seeking senior developers, strong communicators, backend engineers, Python experts, AI/ML specialists, and those willing to learn Japanese.
