Official-source-grounded informational app for Japanese specified-skilled-worker (SSW / 特定技能) and related visa procedures. Six anonymous read-only tools cover search, procedure classification, deadlines, document checklists, law updates, and zairyu compatibility.
Server has 9 tools with clear naming (verb_noun pattern) and detailed descriptions (100-250 chars, well above 20-char minimum). However, critical gaps exist: input schemas are not visible in provided source code, parameter descriptions are absent, and output schemas are undocumented. Tools 7-9 (write operations) lack explicit error handling guidance and confirmation patterns. Read-only tools (1-6) are well-described but lack actionable parameter constraints. No evidence of pagination support for list_law_updates despite potential for large result sets.
Returns the Japanese visa procedure type (certificate of eligibility issuance / status change / period renewal / specified-activity bridge) the user likely needs, grounded in 出入国在留管理庁 official procedure rules. Use when the user asks which procedure they need given a current status, target status, location, and optional SSW industry. Do not use to decide an individual case outcome. Information only — does not constitute legal advice. Does not accept personal identifiers.
Returns the statutory deadline timeline (notifications of changes within 14 days, annual report April 1 – May 31, earliest renewal 3 months before expiry, Specified Skilled Worker (i) 5-year cumulative cap, specified-activity bridge approximately 4 months) for Japanese SSW-class visas, grounded in 出入国在留管理庁 official rules. Use when the user asks when to file a notification, when to file a renewal, or how the overall SSW visa timeline looks. Do not use to calculate a named person's exact filing strategy. Information only — does not constitute legal advice. Does not accept personal identifiers.
Retrieves the current status of a document package submission. Pro-tier tool requiring authentication. Returns the processing status and any validation results.
Returns recent law updates and regulatory changes affecting Japanese SSW visa procedures, grounded in official sources. Use when the user asks about recent changes to visa rules or procedures. Information only — does not constitute legal advice.
No input schemas visible in source code. All 9 tools scored 0 for schema dimension. Cannot verify parameter types, constraints, or descriptions.
Write operations (submit_gyoseishoshi_approval, prepare_document_package) lack explicit error handling guidance and confirmation patterns. No evidence of dry-run, confirmation step, or recovery guidance for irreversible operations.
list_law_updates and list_visa_documents lack pagination parameters (limit, offset, page_size). Large result sets could exhaust context window. No evidence of result capping or cursor-based pagination.

Returns the required document checklist for a specified Japanese visa procedure type, grounded in 出入国在留管理庁 official requirements. Use when the user asks what documents are needed for a specific procedure. Information only — does not constitute legal advice. Does not accept personal identifiers.
Prepares and validates a document package for Japanese visa procedures. Pro-tier tool requiring authentication. Performs document validation and generates a package ready for submission.
Search official Japanese visa procedural information grounded in 出入国在留管理庁 sources. Returns ranked results with source citations. Use for general visa questions, eligibility checks, and procedural lookups. Information only — does not constitute legal advice. Does not accept personal identifiers.
Submits a document package for gyoseishoshi (administrative scrivener) approval. Pro-tier tool requiring authentication. Initiates a multi-round-trip request workflow for document validation and approval.
Validates whether a given current zairyu (residence status) is compatible with a target SSW procedure, grounded in 出入国在留管理庁 official rules. Use when the user asks if their current status allows them to apply for a specific procedure. Information only — does not constitute legal advice. Does not accept personal identifiers.
Output schemas are not documented in source. Cannot verify that tools return structured objects with typed fields, include chaining IDs for downstream calls, or strip unnecessary metadata.
Tool descriptions mention 'does not accept personal identifiers' but no parameter-level constraints are visible to enforce this. LLMs cannot verify compliance without explicit schema validation rules.
