Notion vs Backlog vs Linear: Which Project Tool Works for a Japanese Team?
Three of the most common project management tools in Japan, compared honestly. The right answer depends on who's using it and what you're actually managing.
There’s no universal answer to “which project management tool should we use?” But there are wrong answers for specific situations, and this post tries to make those clear.
I work with Japan SMEs on their operational infrastructure. Project management is one of the decisions that comes up most often — either at the “we have nothing” stage, the “we have too many things” stage, or the “we have the wrong thing for our team” stage.
Notion, Backlog, and Linear are the three tools I see most frequently in the businesses I work with. Here’s an honest comparison.
Backlog (Nulab)
What it is: A project and bug tracking tool built by a Japanese company (Nulab, based in Fukuoka). The closest thing Japan has to a homegrown Jira.
Who uses it: Software development teams and IT departments in Japan. Also common in agencies and consulting firms that deliver projects to Japanese clients. If you’re a developer who worked at a Japanese company in the last decade, you’ve probably used it.
Strengths:
- Excellent Japanese-language support — the entire UI, documentation, and support team are in Japanese
- Familiar to Japanese developers and operations staff — lower change management friction
- Git integration, wiki, and Gantt chart all included without add-ons
- Reasonable pricing: ¥2,970/month for up to 30 users on the Standard plan
Weaknesses:
- The UI feels dated compared to Linear or Notion — it was designed for a different era of project management
- Not great for non-technical operational work (marketing projects, HR processes, etc.)
- Limited flexibility — you work within its structure, not your own
- The free tier is limited enough to be almost unusable for real projects
Best fit: A Japan-based software development team or IT department that needs to track technical work, values Japanese-language support, and has team members who are already familiar with it.
Not a fit: Mixed teams doing both technical and non-technical work, or businesses that need a single tool for documentation AND task management.
Notion
What it is: A flexible workspace that combines wiki/documentation, databases, and project management in one tool. Exceptionally customizable; sometimes dangerously so.
Who uses it: Startups, small creative and operations teams, and anyone who’s spent too long fighting with Confluence. In Japan, adoption has grown significantly in the last three years, particularly in startups and the foreign-operated SME market.
Strengths:
- The most flexible tool on this list — you can make it behave like almost any other tool
- Excellent for documentation alongside task management — knowledge base and project tracker in one place
- Good enough for non-technical teams to actually use without training
- The free tier is genuinely functional for small teams (up to 10 guests)
- AI features (Notion AI) are increasingly useful for drafting, summarizing, and managing information
Weaknesses:
- Flexibility is also a trap — it’s easy to over-engineer and end up with a system nobody uses
- Performance can lag on large databases or complex linked views
- Not purpose-built for software development — if your team needs sprint planning, story points, and GitHub integration, Backlog or Linear will serve them better
- Japanese-language support is adequate but not as polished as Backlog
Best fit: Small to mid-size operational teams who need documentation AND task management, startups, or any team that values flexibility over structure.
Not a fit: Pure software development teams who need sprint mechanics, or large organizations that need rigid permissions and audit trails.
Linear
What it is: An opinionated issue tracker built specifically for software teams. Fast, clean, minimal. Strong opinions about how software projects should be managed.
Who uses it: Software development teams, primarily at startups and growth-stage tech companies. Not yet widely adopted in traditional Japanese enterprise contexts, but growing in the international startup community in Japan.
Strengths:
- The fastest and cleanest UI of the three — optimized for developer workflows
- Excellent GitHub and Git integration — issues link to PRs and commits natively
- Cycle (sprint) planning built in, with proper velocity tracking
- Strong keyboard shortcuts — developers who live in their keyboards love it
- Free tier is genuinely usable for small teams
Weaknesses:
- English-first — Japanese support exists but the product is clearly designed for English-speaking teams
- Opinionated structure means limited flexibility — you work Linear’s way
- Not useful for non-technical work — it’s a software issue tracker, not a general project management tool
- Less familiar to traditional Japanese development teams
Best fit: Software engineering teams, especially those with international exposure or working in English. Startups building products.
Not a fit: Non-technical teams, businesses needing Japanese-language support, or mixed teams doing both software and operational work.
The comparison table
| Backlog | Notion | Linear | |
|---|---|---|---|
| Best for | Japanese dev teams | Ops + documentation | Software startups |
| Japanese support | Excellent | Adequate | Limited |
| Flexibility | Low | Very high | Low |
| Developer workflow | Good | Poor | Excellent |
| Documentation | Wiki (basic) | Excellent | Minimal |
| Free tier | Very limited | Functional | Functional |
| Price (paid) | ¥2,970/month (30 users) | $10/user/month | $8/user/month |
| Learning curve | Low | Medium-high | Low |
What I actually recommend
For most Japan SMEs I work with, the answer is Notion + Backlog or Notion alone, depending on whether you have a technical team.
If you have developers: use Backlog or Linear for technical work (issue tracking, sprint planning, bug reports) and Notion for everything else (documentation, operational projects, meeting notes, onboarding materials). Keep the boundary clear.
If you don’t have developers: use Notion for everything. It can handle most operational project management if you set it up with a clear structure and don’t over-engineer it.
Linear is the right answer if you’re a software-first team and your engineers are the primary users. It’s not the right answer if your team is primarily non-technical or if Japanese-language support is a hard requirement.
The worst outcome is a team with three tools that all partially overlap. If your business is currently running on Backlog AND Notion AND a task list in Slack, that’s a consolidation problem — not a “use all three properly” problem.
If you want a clear read on which tools your team should be using and which you should cut, a Stack Audit is the fastest way to get there.
