Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

entry

get_entry_pack

Paid: return the fixed Iya soba entry-preparation pack with sources, contacts, consultation text, unknowns, and next actions. It gives no customer-specific legal verdict. Japan Rule is not a government service.

search_entry_cases

Free: search the fixed Japan tourism entry-case catalog by region, activity, and language. Returns a model-case preview, key decision themes and what the paid preparation pack adds. It does not include source locations, contact routes, inquiry text or an action plan. Japan Rule is a private commercial service, not a government service.

tourism

get_tourism_evidence_pack

Paid: return official Japanese primary-source URLs, evidence locations, checked dates, source versions, general requirements, traveler-screen checks, and re-check triggers for a complete supported A/B/C flow. This is informational evidence, not a legal verdict.

get_tourism_preflight

Free: classify a Japan-bound hotel service flow into the supported A/B/C model, list missing facts, and flag manual review. It does not return primary-source evidence.

commercial

get_commercial_terms

Free: return the current business-only commercial terms profile for a supported paid product. A status other than ready means Mainnet purchase is unavailable.

evidence

get_evidence_pack

Return a concise evidence pack for one rule ID returned by search_rules. Includes official URLs, scope limits, and no legal-compliance verdict.

rules

search_rules

Search a small curated index of official Japanese sources about mail-order sales advertising. Use this before get_evidence_pack. Results are evidence pointers, not legal conclusions.

Japan RuleWatch — questions

Answers built from our own checks of this server.

What can Japan RuleWatch do?

It exposes 7 tools, read directly from the server on our last check. Among them: get_commercial_terms, get_entry_pack, get_evidence_pack, get_tourism_evidence_pack, get_tourism_preflight, search_entry_cases and 1 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Japan RuleWatch mostly used for?

Its tools cluster around tourism and entry. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Japan RuleWatch working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 184 of 184 checks got a reply (100.0%), average response time 226 ms. The bar chart above shows every period we have measured.

How do I connect Japan RuleWatch?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Japan RuleWatch need an API key?

No. Japan RuleWatch completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Japan RuleWatch?

It answers our handshake in 226 ms on average, which is faster than 62% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Japan RuleWatch open source?

We cannot say either way: written in TypeScript and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
