Tech interviews in Japan: pay, notice periods, and what's different

1. What tech roles pay in Japan (¥)

Pay is in yen, lower than the US but with a wide gap between local and global firms. A senior software engineer:

• Japanese firms (Rakuten, domestic employers): roughly ¥7,000,000 to ¥10,000,000 a year.
• Global-facing firms (Mercari) and foreign offices: ¥10,000,000 to ¥25,000,000 with bonus and equity at the top.

The split is sharp: traditional Japanese employers pay modestly, while foreign offices and the English-first companies pay far more. If you want global-level money in Tokyo, aim at those.

2. Job security and notice periods in Japan

Among the strongest anywhere. Japanese law makes dismissing a permanent employee very hard, a legacy of the lifetime-employment model. Once you're in, you're well protected.

The legal minimum is two weeks for an open-ended contract, but custom is longer. One month is normal, and giving a few months' notice is considered polite.

• Two weeks is the legal floor, but plan for a month or more.
• Generous notice is the cultural norm and protects your reputation.
• If your visa is tied to your employer, sort out the transfer when you move.

If you're looking while still employed, this matters even more. See how to interview while you're still employed.

3. Working culture and turnover in Japan

Traditionally long hours and hierarchical, with consensus-driven decisions, though the English-first companies feel more like a Western tech firm. Politeness and process matter.

Historically very low because of lifetime employment, but rising, especially among younger engineers and at the global-facing firms.

4. What's different about interviewing in Japan

Interviews differ sharply by firm. The English-first companies and foreign offices run global-style loops; traditional Japanese firms run a more conservative, process-heavy process.

• Global-facing firms run standard coding and system-design rounds in English.
• Traditional firms expect Japanese and a more formal, consensus-oriented process.
• Confirm the working language before you prep.

5. Who's hiring in Japan, and what they pay

• English-first tech: Mercari, plus a set of startups that hire and operate in English.
• Large Japanese tech: Rakuten, LINE/Yahoo (LY), PayPay, a mix of Japanese and English depending on the team.
• Foreign offices: Google, Indeed, and others paying closer to global bands.

6. AI and the 2026 market in Japan

Japan's AI push is led by SoftBank's heavy investment and research labs like Preferred Networks, alongside a national drive to catch up in generative AI. Demand for ML engineers is rising at both the global-facing firms and the big domestic players.

7. Language and the international scene in Japan

It depends entirely on the employer. The English-first companies and foreign offices hire with no Japanese, and there's a real 'tech jobs in Japan for foreigners' market. Most traditional firms expect business Japanese, and daily life is far easier with some.

More language-gated than Singapore or Hong Kong, but there's a genuine and growing English-speaking engineering scene, especially in Tokyo. Mercari's switch to English is the best-known example.

8. Working in Japan: visas and right to work

Most foreign engineers come on the Engineer / Specialist in Humanities visa, where the employer sponsors a Certificate of Eligibility first (one to three months). High earners can use the points-based Highly Skilled Professional visa, which is faster and leads to permanent residence sooner.

9. How to prepare for a Japan interview

Loops in Japan run long and lean on consensus. Expect four to six rounds over three to six weeks, with HR, technical, and a final panel that weighs cultural fit and long-term commitment as heavily as coding. Algorithmic rigor is usually lighter than a US Silicon Valley loop, and interviewers reward clear thinking-aloud even on incomplete solutions. Language splits the market sharply. Mercari and Woven run English-first loops, while many domestic employers interview partly in Japanese and ask for JLPT N2 or N1. Punctuality, humility, and prepared reverse-questions all matter.

How the loop actually runs shifts by employer. A few of Japan's best-known names:

• Mercari: English-first loop. A take-home coding assignment (build a pub/sub web API that scales to roughly 200k RPS, with unit tests and docs, about eight hours of work), then three to four rounds: technical, hiring manager, director, and HR/offer. Some coding rounds use three LeetCode-medium problems in an hour. Averages about 22 days.
• Woven by Toyota: English-first, six rounds plus a take-home. A 30-minute recruiter screen, a command-line data-parsing take-home in any language (two to four hours), two technical rounds mixing live coding with domain questions from Linux internals to the browser DOM, a cross-functional round with more live coding, and a final director round. No LeetCode-hard problems reported. Timeline can stretch to months.
• LINE / LY Corp: Four to five stages: CV screen, a Codility test (about five tasks in three hours, medium level), a roughly two-hour video interview with two engineers, a 1.5-hour final with two managers, and a 30-minute HR round. Technical rounds cover databases, OS, concurrency, and algorithms, plus one system-design prompt such as designing a messaging system. Around four to six weeks.
• Rakuten: Operates in English internally. A recruiter screen focused on English and background, a behavioural manager round (expect why Rakuten and why Japan), and a technical round that may include an online LeetCode-medium assessment plus basic full-stack questions. Candidates describe it as lower pressure than a typical FAANG loop, with more weight on cultural alignment. Averages about 36 days.

These loops describe engineering hiring. Management and leadership candidates (Engineering Manager, Director, VP) meet a similar local process but a different bar, so pair this page with the leadership interview prep hub and your role guide.

Questions worth preparing for an interview in Japan:

• Please introduce yourself (jikoshoukai): a short structured summary of your work history.
• Why do you want to work in Japan, and do you plan to stay long term?
• Why this company specifically, and how is it different from a competitor?
• What are our company values? (Mercari candidates report being asked this directly.)
• Tell us about a time you collaborated with a team to solve a problem.

The role itself doesn't change at the border. A senior engineer is held to a senior engineer's bar wherever you are, so the substance of your prep comes from the role-by-role guides and the 2026 Tech Interview Report: the questions, the level, and the common mistakes for your exact role. This page is the local layer on top: pay in ¥, the right timeline, and a process that shifts with the company. It's also worth reading why strong candidates get rejected, since those mistakes travel everywhere. And wherever you interview, the prep that actually transfers is rehearsing out loud — run a mock interview before the real one.
