Key Takeaways
- Japan's tech market splits into three segments - foreign-owned companies, modern Japanese startups, and traditional SI firms - with very different pay, culture, and language requirements.
- Foreign-owned companies and startups hire in English routinely; traditional system integrators generally do not.
- Engineer salaries in Japan sit below US and Western European levels but come with lower living costs and strong stability.
- Japanese ability is the single largest lever on your options, and even N3 to N2 measurably widens the market.
- Japan has an ongoing engineer shortage, which makes it genuinely more accessible than most people expect.
Japan is one of the more accessible developed markets for foreign software engineers, and that is not widely understood. There is a persistent, well-documented engineer shortage, immigration is predictable with no lottery, and a real segment of the market operates in English.
What trips people up is treating "tech jobs in Japan" as one market. It is at least three, and they differ so much in pay, working culture, and language expectation that advice about one is actively misleading about another.
This guide covers the segments, what each expects, and how to target the right one.

The Three Segments
Foreign-owned companies
International technology companies with Tokyo offices, plus foreign financial institutions with substantial engineering teams.
Language: English is frequently the working language. Japanese helps socially and for some client-facing work, but many roles genuinely do not require it.
Pay: the highest in the market, sometimes approaching international levels.
Culture: closer to the parent company's norms than to traditional Japanese practice.
Competition: the most intense, because every English-speaking engineer in Japan is applying to the same short list.
Modern Japanese tech companies and startups
Domestic product companies, particularly in web services, e-commerce, fintech, and gaming. Some have adopted English as an official internal language; more operate in Japanese with English tolerance.
Language: varies enormously. Some are genuinely bilingual; many expect functional Japanese.
Pay: competitive by Japanese standards, often with equity at startups.
Culture: generally more modern than traditional firms - flatter, faster, more remote-friendly.
Opportunity: frequently the best combination of interesting work and realistic accessibility.
Traditional SI and SES firms
System integrators and staffing companies that place engineers onto client projects. A very large part of Japan's IT employment.
Language: Japanese, almost always, at business level.
Pay: typically the lowest of the three, particularly at SES firms where you are placed with clients.
Culture: the most traditional - hierarchical, process-heavy, often with older technology stacks.
Worth knowing: the multi-layer subcontracting structure common in this segment means the company hiring you may not be the company you work at. Understand the arrangement before accepting.
Be selective here. Some are decent employers; the segment also contains the least favourable conditions in Japanese IT. Research any specific company carefully rather than assuming.
What the Market Wants
Backend engineering. Java, Go, Python, Ruby, PHP, and Scala all have real demand. Ruby has an unusually strong position in Japan compared with other markets.
Frontend and mobile. React, TypeScript, Vue, Swift, Kotlin.
Infrastructure and SRE. AWS, GCP, Kubernetes, Terraform. Consistently in demand and often the easiest segment to enter without Japanese, because the work is less communication-dependent.
Data and machine learning. Growing, particularly in e-commerce, advertising, and manufacturing.
Gaming. A genuine specialism where Japan is a global centre - Unity, Unreal, C++, and engine work.
Embedded and industrial. Manufacturing, automotive, and robotics. Often requires Japanese but is a real strength of the market and less competed for by foreign applicants.

How Much Japanese You Actually Need
This is the single largest determinant of your options.
No Japanese. Restricted to foreign-owned companies and a subset of English-operating startups. A real market, but small, and correspondingly competitive.
N4 to N3. Daily life becomes much easier and some bilingual companies open up. Signals commitment to employers, which matters more than the level itself at this stage.
N2. The practical threshold where the market widens substantially. Most Japanese companies will consider you, and this is where the effort starts paying disproportionate returns.
N1. Full access, including traditional firms and management tracks.
Worth knowing: JLPT level also contributes points under the Highly Skilled Professional visa system, which affects your route to permanent residency - see the Japan work visa guide.
The realistic picture without Japanese is in working in Japan without Japanese.
Compensation
Specific figures date quickly, so treat this structurally.
Japanese engineer salaries sit below US and Western European levels, sometimes substantially, particularly at senior level where the gap widens. Foreign-owned companies close much of it.
Living costs offset part of the difference. Tokyo is expensive but generally less so than San Francisco, London, or Singapore for equivalent quality of life, and healthcare and transport are inexpensive by comparison.
The package structure differs. Many Japanese companies pay a substantial portion as bonus - often expressed as a number of months' salary paid twice yearly - so the monthly figure understates annual compensation. Always ask how many months of bonus are typical and whether they are guaranteed or performance-based.
Job-hopping is less rewarded than in the US. Tenure and internal progression still carry weight at traditional firms, though this is changing at modern companies.
The negotiation approach differs from Western norms - see Japan salary negotiation.
Getting Hired
Prepare both documents
Japanese applications expect a rirekisho and a shokumu keirekisho, not a Western resume - even at many international companies in Japan. See the shokumu keirekisho guide and the rirekisho guide.
Providing these correctly signals familiarity with local convention and costs you nothing.
Use the right channels
Bilingual recruitment agencies serve the foreign professional market specifically and are genuinely useful here - more so than in many markets, because they understand which employers actually hire foreigners. Beyond that, LinkedIn works for international companies, and domestic platforms carry the broader market. See the best job sites in Japan.
Expect a different interview
More rounds than you may be used to, more formality, and more questions about your intentions and how long you plan to stay. Employers weigh commitment heavily, and a vague answer costs offers. See Japan interview etiquette.
Technical rounds vary by segment - foreign companies and startups often run coding interviews similar to international norms, while traditional firms may focus more on background and fit.
Address the practical questions early
Visa status, Japanese level, and whether you are already in Japan. Being in-country is a genuine advantage; if you are, say so on the first line.
Common Mistakes
Treating Japanese IT as one market. Foreign-owned companies, modern startups, and traditional SI firms differ so much in pay, culture, and language expectation that a single strategy fits none of them well.
Applying only to the famous international companies. Everyone with English does this, which makes the most visible segment the most competitive - modern Japanese startups often offer better odds and comparably interesting work.
Sending a Western resume. Japanese applications expect a rirekisho and shokumu keirekisho, and providing them signals familiarity with local convention while a one-page resume signals unfamiliarity.
Not learning any Japanese. Even N3 measurably widens your options and signals commitment, and the effort compounds - N2 in particular opens most of the domestic market.
Accepting an SES role without understanding the structure. Multi-layer subcontracting means the company hiring you may not be the company you work at, and conditions vary widely across that segment.
Being vague about how long you plan to stay. Japanese employers weigh commitment heavily and interpret ambiguity unfavourably, so a specific, honest answer is worth preparing.
Comparing salary on the monthly figure alone. Bonus is often a substantial share of annual pay, so the headline monthly number can significantly understate the package.
Ignoring the Highly Skilled Professional points system. Japanese language qualifications and salary both add points, and qualifying substantially shortens the route to permanent residency.
Frequently Asked Questions
Can I get an IT job in Japan without speaking Japanese?
Yes, at foreign-owned companies and some English-operating startups. That segment is real but small and competitive, so no Japanese means a narrower search rather than an impossible one.
How do Japanese tech salaries compare internationally?
Generally below US and Western European levels, particularly at senior grades, though foreign-owned companies close much of the gap. Lower living costs and inexpensive healthcare offset part of the difference.
Is Japan a good place for a software engineering career?
It depends on priorities. Compensation is lower than in the US, but there is a genuine engineer shortage, immigration is predictable, and stability and quality of life are strong. The gaming and embedded sectors in particular are world-class.
What is an SES company?
A staffing firm that places engineers onto client projects, often through several layers of subcontracting. It is a large part of Japanese IT employment, and conditions vary widely - research any specific company carefully.
Which JLPT level do I need?
None for English-language roles. N3 helps and signals commitment; N2 is the practical threshold where most Japanese companies will consider you. N1 opens everything including management tracks.
Do I need a rirekisho and shokumu keirekisho for international companies?
Many in Japan expect both even when hiring in English. Providing them is a low-cost signal that you understand local convention.
Is remote work available?
More than before, particularly at modern startups and foreign-owned companies. Traditional firms remain more office-oriented, and fully remote roles that would let you work from outside Japan are uncommon.

Make This Practical
Pick your segment before applying, because the three parts of the Japanese IT market want different things. If you have no Japanese, target foreign-owned companies and English-operating startups deliberately rather than applying broadly and reading silence as bad luck.
Then prepare the documents Japan actually asks for - a rirekisho and a shokumu keirekisho rather than a Western resume, using the shokumu keirekisho guide - and state your visa status, Japanese level, and whether you are already in Japan on the first line.
Finally, start Japanese even if your target roles do not require it. N3 signals commitment and N2 opens most of the domestic market, and JLPT level also adds points toward the Highly Skilled Professional status described in the Japan work visa guide.
