7 IT Japanese Terms That Will Transform Your Tech Career

I remember the first time I was asked to "check the shiyou" on a new project. I nodded, a fake smile plastered on my face, while my mind raced, scrambling for a translation. Was it "check the spec"? The "spec sheet"? The "specifications"? Turns out, it was all three. That single moment of confusion, a tiny linguistic hiccup, felt like a massive roadblock, highlighting just how much I had to learn to truly thrive in a Japanese IT environment. It wasn't just about grammar—it was about a whole new way of thinking, of communicating, and of understanding the unwritten rules of the game.

The truth is, working in tech in Japan isn't just a career move; it's an adventure. It's exhilarating and frustrating, often at the same time. The technical jargon you've mastered in English—all those acronyms, buzzwords, and elegant phrases—suddenly feel as useful as a floppy disk in a modern data center. You quickly realize that a direct translation often falls flat, and sometimes, there's no equivalent at all. You have to immerse yourself, not just in the language, but in the culture of the workplace. It's a journey from simply coding to truly collaborating, and it all starts with the right words. Today, I'm pulling back the curtain and sharing seven indispensable Japanese IT terms that I've learned the hard way—and trust me, they're worth their weight in gold.

This isn't just another vocabulary list. This is a survival guide. It’s a road map to avoiding awkward silence, impressing your colleagues, and, most importantly, getting things done. We'll go beyond the basics like gijutsu (technology) and sofuto-wea (software) and dive into the practical, day-to-day terms that make a real difference. If you're ready to stop guessing and start knowing, you've come to the right place. Let’s get into it.

The Essential IT Japanese Vocabulary for Your First Week

When you first land in a Japanese tech company, the sheer volume of new terms can feel overwhelming. It's like being a freshman again, but instead of learning biology, you're trying to figure out if Kaizen is a person or a process. Don't panic. The key is to start with a few foundational terms that will help you survive, and even shine, in daily meetings. These aren't just words; they're concepts that define the very workflow and culture of many Japanese organizations.

1. 開発 (かいはつ) — Kaihatsu — Development. This is the big one. It's the central pillar of any software or product company. When you hear this word, you know it's about building something new. But it's more than just coding; it's the entire lifecycle. Think of it as the umbrella term for everything from planning and design to coding and testing. For example, your manager might ask, "この新しい機能のkaihatsuはいつ始まりますか？" (When will the development for this new feature begin?). Knowing this term instantly gives you context for the conversation.

2. 仕様 (しよう) — Shiyō — Specification. Ah, the infamous shiyō. This word is the source of many an IT professional's headaches, yet it's absolutely critical. It refers to the detailed requirements, specs, and design documents for a project. If you're a developer, you live and die by the shiyō. It’s what tells you exactly what to build, how it should behave, and what the user should see. A common phrase you'll hear is "shiyō通りに実装してください" (Please implement it according to the specifications). So, when in doubt, check the shiyō!

3. 進捗 (しんちょく) — Shinchoku — Progress. This is the word you'll hear in every single stand-up, every status meeting, and probably in your dreams. Shinchoku is the progress of a task or a project. Your manager's favorite question will be "shinchokuはどうですか？" (How's the progress?). Being able to answer this question clearly, with terms like "順調です" (junchou desu - it's going smoothly) or "少し遅れています" (sukoshi okureteimasu - it's a little behind schedule), is a crucial skill. It shows you're on top of things and in control.

4. 不具合 (ふぐあい) — Fuguai — Bug/Malfunction. Every developer knows the pain of finding a bug. In Japanese, it's a fuguai. While loanwords like "bug" (バグ - bagu) are often used, fuguai is a more formal, all-encompassing term for any sort of malfunction or issue. Using this word shows you understand the nuance and professionalism of the Japanese workplace. When a user reports a problem, you might say, "ユーザーからfuguaiの報告がありました" (There was a bug report from a user).

Beyond the Basics: From Kaihatsu to Shinchoku

Once you’ve got the basics down, it’s time to level up. This is where the real fun begins. Japanese tech culture, especially in software development, is deeply influenced by lean manufacturing principles. Words that might sound like they belong on a factory floor are used every day in the most high-tech offices in Tokyo and beyond. Embracing these concepts will not only help you speak the language but also understand the core philosophy behind the work.

5. 改善 (かいぜん) — Kaizen — Continuous Improvement. This is arguably one of the most famous Japanese business terms, and for good reason. Kaizen isn't a one-time thing; it's a philosophy of constant, small improvements. In tech, this means iterative development, A/B testing, and always looking for ways to make a process more efficient or a product better. It's the opposite of a "big bang" release. It’s about making tiny tweaks that compound over time. A good manager will encourage you to practice kaizen in your own work.

6. 共有 (きょうゆう) — Kyōyū — Sharing. Information is power, but in a collaborative environment, sharing that power is key. Kyōyū means to share, and it's a fundamental part of the Japanese workplace culture. This isn't just about sharing documents; it's about sharing knowledge, progress updates, and problems. In a meeting, you might be asked to "情報をkyōyūしてください" (Please share the information). It’s a polite and professional way of asking for a status update or an explanation.

7. 着手 (ちゃくしゅ) — Chakushu — To Start a Task. This is another term that sounds simple but carries a lot of weight. While you can use the more common "始める" (hajimeru) for "to start," chakushu is a more formal, industry-specific term. It implies that you're not just beginning something, but you're officially embarking on a task or project. When you get the green light, you might say, "明日からこのタスクにchakushuします" (I will start this task from tomorrow). Using chakushu shows a level of commitment and professionalism that your colleagues will notice.

Don't Get Lost in Translation: Common Pitfalls and Misconceptions

As I’ve learned firsthand, simply knowing the words isn’t enough. The real challenge—and the real fun—comes from understanding the context. A word that means one thing in a dictionary can have a completely different feel in a meeting. For instance, the casual "what's up?" you might say in a US-based office could be seen as too informal in Japan. Similarly, some terms are loanwords from English but have been repurposed or had their meaning slightly shifted. This is where the subtle art of communication comes in.

One of the biggest traps is assuming a katakana word has the exact same meaning as its English counterpart. Take "appu" (アップ) for example. While it can mean "up," it's often used to mean "to improve" or "to upgrade," as in "sutairu appu" (スタイルアップ) meaning "to improve one's style." The same goes for tech-specific terms. "Sāba" (サーバー) is obviously "server," but "pasokon" (パソコン) is a shortened form of "personal computer" and is the everyday word for a desktop or laptop, while "konpyūta" (コンピューター) is a more general, formal term.

Another common pitfall is not understanding the concept of hōkoku, renraku, and sōdan (報告, 連絡, 相談), often abbreviated as the Hō-Ren-Sō (ほうれんそう) framework. This is a fundamental principle of Japanese business communication that stresses the importance of reporting, communicating, and consulting. It's a system to ensure everyone is on the same page and that problems are addressed quickly. It's not just about a daily stand-up; it's a mindset that emphasizes proactive communication and mutual support. For example, if you encounter a problem, you don't just solve it on your own; you hōkoku (report) it to your superior, renraku (communicate) the situation to your team, and sōdan (consult) with your manager on the best course of action. This might seem like over-communication to a Western mindset, but it's the very fabric of how things get done in Japan.

Learning these nuances is like learning a new operating system. It’s not just about knowing the commands; it's about understanding the logic and architecture behind them. It takes time, patience, and a willingness to make mistakes. But every time you use a term correctly or understand a subtle reference, you'll feel a tiny surge of victory, a small step forward in your career journey.

Visual Snapshot — A Day in the Life of a Japanese Developer

   

This infographic illustrates the cyclical nature of work in many Japanese tech environments. It starts with the morning meeting (Asakai), which sets the stage for the day's tasks. Then comes the core work of planning and development. When an issue arises, it triggers a cascade of actions that involves reporting and consultation. Crucially, the process doesn't end with a fix. The philosophy of Kaizen ensures that every step is reviewed for potential improvements, creating a continuous loop of refinement. This is why knowing these words is so vital—they aren’t just individual terms, but pieces of a much larger, interconnected system.

FAQ

Q1. Are all Japanese tech terms loanwords from English?

No, not all of them. While a significant number of terms, like "server" (サーバー) and "programming" (プログラミング), are loanwords (gairaigo) written in katakana, many essential industry terms are original Japanese words, often written in kanji, such as kaihatsu (開発 - development) and shiyō (仕様 - specification). The balance between the two can depend on the company and the specific context.

Q2. Is it rude to use English loanwords in a Japanese company?

Generally, it is not rude to use common loanwords, as they are part of the modern Japanese lexicon. However, using a mix of loanwords and native Japanese terms demonstrates a deeper understanding and respect for the language and culture. For example, using fuguai (不具合) instead of just "bagu" (バグ) can be seen as more professional and precise in a formal setting.

Q3. What is the difference between Kaihatsu (開発) and Jissō (実装)?

This is a great question. Think of Kaihatsu (開発) as the broader process of "development," which includes everything from planning to deployment. On the other hand, Jissō (実装) is more specific, referring to the "implementation" or the actual act of writing the code and building the feature. You would say "新しい機能をjissōする" (to implement a new feature) as part of the overall kaihatsu process.

Q4. What is the Japanese term for a daily stand-up meeting?

The most common term is Asakai (朝会), which literally means "morning meeting." This is a quick, often informal, meeting where team members share their progress and plans for the day. It's a key part of the communication culture in many Japanese companies.

Q5. How do I ask "what's the progress?" politely?

The most polite and common way to ask this is "shinchokuはいかがですか？" (Shinchoku wa ikaga desu ka?). This is a formal way to inquire about the progress of a task or project. It's polite because it uses the honorific "ikaga" and "desu ka" structure. For a slightly less formal but still professional tone, you can say "shinchokuはどうですか？" (Shinchoku wa dou desu ka?).

Q6. Is "Kaizen" just for manufacturing?

No, not at all! While the term originated in manufacturing, particularly at Toyota, the philosophy of Kaizen—continuous, small-scale improvement—is a cornerstone of many Japanese businesses, including those in the IT and tech sectors. It's applied to everything from code optimization and workflow efficiency to product design and user experience. It's about a constant pursuit of perfection in all aspects of work.

Q7. What is the Japanese term for a bug?

As mentioned, the most common native Japanese term is fuguai (不具合). It means "malfunction" or "defect." The English loanword "bug" is also widely used and pronounced as bagu (バグ). In formal settings, using fuguai is often preferred, but in a casual conversation with colleagues, bagu is perfectly acceptable.

Q8. How do I prepare for a Japanese tech interview?

Beyond technical skills, focus on mastering key communication terms like hōkoku (reporting), renraku (communication), and sōdan (consultation). You should also be prepared to discuss your experience in terms of projects you have worked on (purojekuto) and the specific roles you've held. Demonstrating an understanding of Japanese work culture and a willingness to learn is just as important as your technical expertise.

Q9. Are there terms for agile or scrum in Japanese?

Yes, many agile and scrum terms are commonly used as loanwords. "Agile" is アジャイル (ajairu), and "Scrum" is スクラム (sukuremu). Within these frameworks, you'll also hear terms like "sprint" (スプリント - supurinto) and "backlog" (バックログ - bakkurogu), though these are often mixed with native Japanese terms for tasks and progress.

Final Thoughts

Navigating the Japanese tech world is more than just about learning a new language. It’s about a complete cultural recalibration. The little victories—correctly using shiyō in a meeting, understanding the nuance of Kaizen, or confidently explaining your shinchoku—are what make the journey so rewarding. Don't be afraid to make mistakes; they're your best teachers. Each slip-up is an opportunity to learn, to grow, and to become a more effective, and more valuable, member of your team. The tech industry in Japan is a fascinating, dynamic place, and with the right vocabulary in your toolkit, you're not just surviving, you're building a bridge between cultures. So, go out there, be bold, and start speaking the language of Japanese tech. Your future self will thank you for it.
