Many companies in Japan now have more software work than engineers to do it. IT departments wait months to hire, web and system development companies turn down projects, and startups compete with large firms for the same people. Offshore development is one of the most common answers.
Offshore projects also have a reputation in Japan for going wrong: specifications misunderstood, quality below expectations, and communication that takes more management time than it saves. Most of these problems are predictable, and most can be avoided by choosing the partner carefully and starting the right way. This guide explains what to check, written by a team that does this work every day.
Why do companies in Japan look for offshore development partners?
The main reason is the shortage of engineers. In its 2019 study of IT talent supply and demand, Japan's Ministry of Economy, Trade and Industry (METI) projected that the shortage of IT workers could reach around 790,000 people by 2030 in its highest scenario. METI's DX reports also warned about the cost of ageing legacy systems, often called the 2025 cliff. Whatever the exact number, most Japanese companies feel the shortage directly when they try to hire.
Speed and cost are the other reasons. An offshore team can usually start in weeks instead of the months it takes to hire, and it can grow or shrink with the work. Cost can be lower, but it should not be the only reason. A cheap partner who needs constant correction is often more expensive in total than a slightly more expensive one who gets it right.
Vietnam, the Philippines, China and India are all common choices. India has a very large pool of engineers, deep experience in web, mobile and cloud work, and is only 3.5 hours behind Japan.
What should you evaluate in an offshore development partner?
Before comparing prices, compare how each partner actually works. Ask them to show rather than describe: a sample requirements document, a sample weekly report, a test plan from a past project. The checklist below covers the points that decide most outcomes.
- Communication: who you talk to every day, in which language, and how quickly questions are answered.
- Requirements: how they write requirements, how they confirm their understanding with you, and how changes are handled.
- Documentation: what you receive during the project and at hand-over, such as specifications, design files, API documents and setup guides.
- QA and quality: who tests, when testing happens, which devices and browsers are covered, and how bugs are tracked and reported.
- Security and NDA: whether they will sign your NDA, how access to code, servers and data is controlled, and how that access is removed when the project ends.
- Code and IP ownership: the contract should state that source code, designs and intellectual property belong to you, and the code should live in a repository you own.
- Time-zone overlap: how many working hours you share and when meetings can happen.
- Team stability: whether the people named in the proposal are the people who will do the work.
How should requirements and communication work across languages?
Most offshore failures start during requirements definition. In Japanese companies, a lot of meaning is shared through context, and a specification that is clear to a Japanese team can leave gaps for a team abroad. The fix is to make everything explicit and written.
Good partners work written-first. Requirements, decisions and changes are written down and confirmed, not only discussed in a meeting. They repeat requirements back in their own words, ask about edge cases, and show screens and flows with prototypes or annotated designs before writing code. Visual material removes more misunderstanding than any amount of explanation.
Language is a practical choice. Some vendors provide a Japanese-speaking bridge engineer (a bridge SE) who translates between your team and the developers. Others, including many smaller senior teams, work in English with translation and AI tools for documents, live translation and meeting summaries. Both can work. Decide which your organisation needs before you choose, and test it during the trial.
Time zones help. India Standard Time is 3.5 hours behind Japan Standard Time, so the Indian morning overlaps with the Japanese afternoon. A team that starts at around 9:30 in India is online from about 13:00 in Japan, which leaves several shared hours each day for calls and quick answers.
Why start with a small paid trial or discovery phase?
A large first contract is the riskiest way to start, because you only learn how a partner really works after working with them. A small paid phase of two to four weeks gives you that knowledge at low cost.
Good first phases are a discovery phase (requirements, user flows, technical approach and an estimate), a clickable prototype, or one well-defined feature built into your existing system. Pay for it. Free trials create the wrong incentives and rarely show real working habits.
At the end, judge the questions they asked, the quality of their documents and code, how they handled feedback, and whether their estimate for the next phase is clearly reasoned. If the trial is difficult, the full project will be harder.
Project-based or lab-style development: which model fits?
Japanese companies usually choose between two models. In project-based development, the partner delivers a defined scope by an agreed date. It works well when requirements are clear and stable, for example a new app or the replacement of a specific system.
In lab-style development, you reserve a dedicated team, usually month by month, and direct the work yourself. It fits ongoing product development, requirements that are still changing, and agencies that need steady extra capacity. It needs more involvement from you: someone on your side must set priorities and review the work.
Many companies start with a discovery phase or a small project, then move to a lab-style team once trust and shared understanding are in place.
What are the common failure points, and how do you avoid them?
Most failed offshore projects fail for the same few reasons. Each one has a simple counter-measure.
- Unwritten assumptions: write down business rules, edge cases and acceptance criteria, and ask the partner to confirm them in writing.
- Too little contact: hold a weekly call and keep a shared channel for daily questions, so problems surface early.
- Testing only at the end: ask for a working build every week or two and test it yourself.
- No clear owner on your side: name one person who can answer questions and make decisions quickly.
- Choosing on price alone: compare the total cost, including your own management time and rework.
- Losing control of assets: keep code, design files, cloud accounts and domains under your company's ownership from the first day.
How does Devnori work with companies in Japan?
Devnori is a small, senior product design and engineering studio based in India, working remotely with clients worldwide. Product design, UX/UI, web and mobile (iOS and Android) development, AI and automation, cloud and DevOps, and QA come from one connected team, so there is no hand-off between a design agency and a development company. The team has shipped more than 60 projects, including web platforms, mobile apps and internal tools, and builds and runs its own products such as Opticdigit, TrainFoxx and Securelyze.
We offer both models described above. A Project has a defined scope delivered end to end: a discovery and scoping workshop, a dedicated designer and engineers, a weekly sync call, regular updates, and hand-over with documentation. An Extended team gives flexible monthly capacity inside your tools and routines, close to what Japanese companies call lab-style development. For agencies, we also work as a white-label partner under your name and NDA, and you keep the client relationship.
We work across languages with written-first requirements, AI-assisted calls with live translation and summaries, and visual communication through prototypes, flows and annotated screens. To be honest about fit: we do not have Japanese-speaking staff. If your project needs a Japanese-speaking bridge SE on the vendor side, or all documents written natively in Japanese, another partner will suit you better. We do not publish prices. Every project is scoped after a first call, we say early if we are not the right fit, and we reply within 24 hours, Monday to Friday.
