Business software and the SME tech stack in Japan
Notion vs Backlog vs Linear: which suits a team in Japan?
Notion, Backlog and Linear compared for teams in Japan: Japanese support, documentation, developer workflow and which to choose for mixed or bilingual teams.
For most small teams in Japan, the choice comes down to the kind of work. Backlog is the safest choice for Japanese-speaking teams running projects with clients, vendors or developers. Notion suits small teams that need documentation and task lists in one place. Linear is the best fit for software teams that work in English. If you have developers and a non-technical team, a common setup is Backlog or Linear for technical work and Notion for everything else, with a clear rule about which work goes where. What you should avoid is all three running at once with tasks scattered across them.
These three tools overlap without being interchangeable. Backlog is a project tracker, Notion is a flexible workspace, and Linear is an issue tracker for engineers. Start from the work that currently gets lost.
What is Backlog, and who is it for?
Backlog is a project and issue tracking tool made by Nulab, a Japanese company founded in Fukuoka. It is often described as Japan’s answer to Jira, and many Japanese developers, IT departments, agencies and SIers have used it.
Strengths. The interface, help documentation and support are fully Japanese, which lowers the effort of getting staff to adopt it. It includes a wiki, Git repositories and Gantt charts in one product. Because many Japanese vendors already use it, it is easy to invite an outside developer or agency into your project.
Weaknesses. The interface feels older than Notion or Linear. It works best for work that fits a project, issue and milestone structure, and is less natural for open-ended operational work such as marketing calendars or HR processes. The wiki is basic compared with Notion.
Best fit. Japanese-speaking teams managing projects with defined tasks and deadlines, especially where outside vendors or developers are involved. I compare it with the international alternative in Backlog vs Jira.

What is Notion, and who is it for?
Notion combines documents, wiki pages, databases and task boards in one workspace. You can build almost any structure in it, which is both its appeal and its main risk.
Strengths. It is the best of the three for documentation: procedures, onboarding material, meeting notes and a company knowledge base can sit next to the task lists that refer to them. Non-technical staff can use it with little training. The interface is available in Japanese, and adoption has grown among Japanese startups and foreign-run companies. Its AI features help with drafting and summarizing.
Weaknesses. Flexibility makes it easy to over-build. I often see workspaces with dozens of linked databases that only the person who built them understands. Large databases can feel slow. It has no real developer workflow, so software teams usually outgrow it for issue tracking.
Best fit. Small operations, creative and bilingual teams that need a shared knowledge base as much as a task tracker, and companies without developers.
What is Linear, and who is it for?
Linear is an issue tracker built for software teams. It is fast, keyboard-driven and opinionated about how engineering work should run.
Strengths. It has the quickest interface of the three, strong GitHub and GitLab integration that links issues to pull requests, and built-in cycles for planning sprints. Developers tend to like it.
Weaknesses. The interface is English-first. Staff can write issues and comments in Japanese without problems, but menus and help are in English, which matters for Japanese-speaking teams. It is not designed for non-technical work, and fewer traditional Japanese development vendors use it.
Best fit. Product and engineering teams, especially those that work in English or with international developers.
How do they compare side by side?
| Backlog | Notion | Linear | |
|---|---|---|---|
| Built for | Project and issue tracking | Documents, wiki and tasks | Software issue tracking |
| Japanese interface and support | Full | Available | English-first |
| Documentation | Basic wiki | Strong | Minimal |
| Developer workflow | Good (Git, issues) | Weak | Strong |
| Non-technical work | Workable | Strong | Poor |
| Flexibility | Moderate | Very high | Low |
| Familiar to Japanese vendors | Very | Growing | Less common |
Prices change often and depend on team size, so compare current plans on each vendor’s site once you have narrowed the choice.
Which should a small team in Japan choose?
A Japanese-speaking team with outside vendors or developers
Choose Backlog. Its Japanese support and familiarity among local vendors outweigh the older interface. Add Notion only if you have a real need for a knowledge base that Backlog’s wiki cannot meet.
A small operations or bilingual team without developers
Choose Notion, and keep the structure simple: one task database, one place for procedures, one place for meeting notes. Resist building a custom system for every department.
A software product team
Choose Linear if the team works in English, Backlog if it works mostly in Japanese or collaborates with Japanese vendors. Keep company documentation in Notion or your Google Workspace or Microsoft 365 files.
A company that wants custom business apps rather than a task tool
If what you really need is structured records such as inspection reports, orders or requests with approvals, look at kintone rather than any of these three.
What mistakes should you avoid?
Running all three. If tasks live in Backlog, Notion and a Chatwork thread, nobody knows which list is current. Pick one home for each type of work and write the rule down. The post on cutting overlapping SaaS subscriptions covers how to consolidate.
Choosing for the manager, not the team. The people entering tasks every day decide whether the tool survives. Let two or three of them test it on real work for two weeks before you commit.
Moving everything at once. Migrate active projects first, archive the rest, and set a date after which the old tool becomes read-only.
No owner. Someone has to tidy statuses, archive finished work and add new staff. Without that, any of these tools turns into a list nobody trusts.
Where this fits in the wider stack
The task tool is one layer of the stack. It needs to sit alongside your chat tool, file storage and customer records without duplicating them. For the full picture, see what software a small business in Japan should use.
If your team already has overlapping tools and you want a clear decision on which to keep, a Diagnostics review looks at how work actually moves through the business. If the decision is made and you need the migration done, I can set up the tool and move the team across.
