Working as an Engineer in Japan

Anyone interviewing/working in Japan should know this. There are unspoken rules in Japanese business culture that many non-Japanese professionals aren’t aware of. One example is the 24-hour email rule. While not written anywhere, there is often an expectation that emails are at least acknowledged within 24 hours, especially in corporate environments. Another very important concept in Japanese business is 結論ファースト, which I usually translate as “conclusion first.” This means that when asked a question, you are expected to start with the conclusion, then explain details. For example, if someone asks: “What’s the bottleneck?” A "conclusion first" answer would be: “The bottleneck is XYZ.” Only after that do you add context or reasoning. A common pattern I see goes like, "Well we investigated X, but we suspected Y to be the bottleneck, so we looked into it...." In many Western interview settings, telling a story or walking through your thought process can score extra points. In Japan, however, leading with detail before the conclusion can be counterproductive. The best analogy I can think of is gift-giving in Japan. Gifts are beautifully wrapped and effortless to open. Japanese business communication works the same way; answers should be easy to “open” and immediately clear. I’ve seen excellent engineers fail interviews not because of a lack of skill, but because they over-talk and delay the conclusion. The best rule of thumb I can give is two-fold: 1. Pay attention to how the question starts. (Is it a yes or no question? Is it a "how," "why," or "when" question?) 2. Don't be afraid to pause before you answer. Some of the strongest candidates I've seen have a quiet confidence around their silence. If you search interview tips in Japanese, 結論ファースト is often one of the first things mentioned, and it's something every New Grad learns as they go through their 就活 (Job Hunting) process which shows how deeply this mindset is embedded in Japanese business culture. I hope knowing this helps. It’s genuinely painful to see great engineers miss opportunities simply because their communication style doesn’t match local expectations. And as a final note, this is also relevant for anyone working in sales in Japan, or even for internal communication!

📚 The Truth Behind “Rejected Due to Insufficient Japanese” 📚 ❌ “Rejected due to insufficient Japanese(日本語力不足でお見送り)” — a phrase many foreign job seekers often hear when applying to Japanese companies. But what does “insufficient” really mean? 🤔 As a recruiter with a background in Japanese language education, I’d like to share the key checkpoints companies actually look at when evaluating candidates’ Japanese ability. 🔑 What Japanese Companies Look At 1️⃣ Experience using Japanese at work → Using Japanese in real work builds strong trust. Even part-time customer service counts as valuable experience. 2️⃣ Listening ability 👂Can you understand instructions and put them into action? In Japan, attentive listening is highly valued. 👉 If you often need to ask for repetition during an interview, it shows you need to improve listening skills. In the short term, learning polite ways to ask for clarification can also be very effective. 3️⃣ Relevance of answers 🎯 Answer exactly what was asked. Going off-topic or speaking too long can hurt your impression. 4️⃣ Cultural adaptability 🌸 Language and culture go hand in hand. Companies unconsciously evaluate whether you can: ✓ Say “ありがとうございます” or “申し訳ございません” naturally ✓ Use appropriate aizuchi (backchannel responses) ✓ Smile and be approachable 5️⃣ Pronunciation 🗣️ A slight accent is fine. But if it makes communication difficult, it may lower your evaluation. 👉 Of course, this also depends on your team’s diversity and the international balance of members! 6️⃣ Logical communication 📝 Explaining in the order of Conclusion → Reason → Summary earns high marks. Ex.） Q:今までのプロジェクトで一番成果を出せた実績と、どうしてそう思うのか理由を教えてください。 A:前職で担当した データ処理パイプラインの改善プロジェクト で、処理速度と安定性を大幅に向上させたことを成果の一つと考えています。 当時は古いスクリプトで冗長なロジックが多く、平均処理時間が10分以上かかっていましたが、新しいライブラリを導入して設計を見直し、コードを簡潔にしました。その結果、処理速度は約3倍、平均処理時間も10分から3分に短縮でき、障害も減少しました。この成果を出せたのは、ユーザーの声を丁寧に聞き取り、原因を正しく把握して無駄な処理を削減できたからだと考えています。 💡 Takeaway When companies say “insufficient Japanese”, they’re not just looking at JLPT scores. They want to know: ➡️ How smoothly can you communicate in real work situations? 🌱 Language learning never ends. But by focusing on these checkpoints, you can improve your impression dramatically. ✨ You don’t need to be perfect — just start small and improve step by step. Especially ④ and ⑥ can be trained even in the short term! 💪 Let’s work on it together!

Have you noticed more software engineers making the move to Japan lately? I certainly have. As a tech recruiter in Tokyo, I’m seeing a growing number of engineers from around the world looking to relocate. Some are following a lifelong dream to experience life in Japan. Others are returning for family reasons. But more and more, I’m hearing from people who want a fresh start because of uncertainty in their home countries. But there’s one challenge that comes up again and again: Adjusting to Japan’s salary levels. Many candidates expect to keep or even increase their salary after moving. The reality? Almost everyone faces a pay cut compared to the US or Europe. I’ve even worked with someone who’s been searching for over a year, unwilling to lower their expectations. Here’s what the numbers look like in 2025: -> Average software engineer salary in Japan: around ¥6–6.5 million per year (about $40,000). -> Entry-level roles: typically ¥4–5 million. -> Senior engineers at top companies: can reach ¥10–12 million, with some international firms offering even higher. And it’s not just about salary, another big hurdle is language. Most roles require a good level of Japanese, which can be a real adjustment for many international candidates. For companies hiring from overseas: It’s important to be transparent about these benchmarks and support candidates through the transition. For engineers thinking about relocating, understanding the local market can help set realistic expectations and make the move smoother. If you’ve relocated to Japan or hired international tech talent, what surprised you most about salaries or benefits? #TechCareers #JapanJobs #Relocation #Recruitment #SoftwareEngineering

Stop studying for the JLPT. 🛑 If your goal is to work as a software engineer in Tokyo, memorizing 2,000+ Kanji for the N1 isn't the fastest path to a job. In fact, it might be slowing you down. I’ve spent 10 years in the Tokyo tech scene, and I see this "shocking" reality constantly: Engineers with N1 certification freezing in technical interviews because they can't explain a simple bug. Meanwhile, engineers with N3—or even N4—are getting hired and thriving. The secret? They speak "Engineer Japanese." In a fast-paced dev team, we don't want a textbook speech. We want status updates and blockers. ✅ Textbook: "私は昨日、ログイン機能を実装しました..." (Sounds like a robot) ✅ Engineer: "Loginできました。今日はテストやります。" (Short, clear, natural) My #1 tip for surviving a Tokyo dev team? Learn the word "Hamaru" (ハマる). It’s not on the JLPT, but it tells your Senior Engineer exactly what’s happening: "I’m stuck on a bug and need a hand." Stop trying to be a linguist. Start being a communicator. I’ve put together a full breakdown of the "Engineer Japanese" phrases that actually matter—including the ones that will help you pass a technical interview even if your Japanese isn't perfect. I’m sharing the full guide and my "Tier 2" Japan Tech Company list in the video below. 👇 Check the first comment for the link! #JapanTech #SoftwareEngineering #TokyoJobs #WorkingInJapan

"You need N2 to work in Japan now." That headline is everywhere. And it's causing a lot of unnecessary panic. The change: As of mid-April 2026, the Engineer/Specialist in Humanities visa now requires proof of Japanese proficiency at JLPT N2 level but only if the role involves Japanese-language communication. That "if" part is important. Here’s what you need to know. Graduates of Japanese universities or schools transitioning directly to employment are exempt. Roles that don't require Japanese, the N2 requirement does not apply. International tech companies, global firms with English-language engineering teams, and startups operating in English have been explicitly cited as unaffected. You only need to submit a JLPT N2 certificate if your application falls under Category 3 or 4.   Note: the vast majority of Japanese companies fall under Category 3 or 4. And N2 isn't the only way to prove proficiency. Acceptable alternatives include a BJT score of 400+, graduating from a Japanese university, completing compulsory education in Japan and graduating from a Japanese high school, or having resided in Japan as a medium-to-long-term resident for 20 years or more. So the bottom line is if you're targeting English-first companies, foreign-affiliated firms, or tech startups, this rule likely doesn't affect you. If you're targeting Japanese SMEs or roles where Japanese is genuinely required, yes, N2 matters. And it's worth taking seriously.
