Japan data tools for AI agents: calendar (rokuyo), address, name splitting, corporate number lookup

Japan-specific data tools for calendar, addresses, names, and corporate lookups.

Captured live from the server via tools/list.

lookup_calendar

Look up Japanese calendar information for a given date: Rokuyo (six-day cycle such as Taian/Butsumetsu), Rekichu (almanac notes), Eto (sexagenary cycle), 24 solar terms, and purpose-based auspiciousness scores. Useful when an AI agent needs canonical Japanese calendar facts (e.g. choosing an auspicious date for a wedding or ceremony). Source: Shirabe Calendar API (shirabe.dev).

Parameters (2)

datestringrequired
Target date in YYYY-MM-DD (between 1873-01-01 and 2100-12-31).
categoriesarray
Optional purpose categories to score (e.g. marriage, funeral, groundbreaking). Omit to return all available categories.

normalize_japanese_address

Normalize a free-form Japanese address against the official Address Base Registry (ABR, all 47 prefectures). Returns the canonical form, structured components (prefecture/city/town/block/building), postal code, WGS84 coordinates, match level (0-4) and confidence, plus mandatory CC BY 4.0 attribution. Useful when an AI agent must clean or de-duplicate Japanese B2B/customer records. Source: Shirabe Address API.

Parameters (1)

addressstringrequired
A raw Japanese address string (may include postal code, building, floor).

split_japanese_name

Split a Japanese personal name into family and given parts using IPAdic person-name POS tags (with whitespace/length heuristics as fallback). Returns family, given, and a confidence score (0-1; warning when low). Useful for normalizing name fields in HR, CRM, or form data. Source: Shirabe Text API.

Parameters (1)

namestringrequired
A Japanese personal name, e.g. 山田良介.

corporation_lookup

Look up a Japanese company by its 13-digit corporate number (法人番号) against the National Tax Agency (NTA) corporate-number registry. Returns the registered trade name, head-office address, change history and other public fields as JSON, plus mandatory NTA attribution. Useful when an AI agent already has a corporate number and needs canonical company facts (e.g. validating or enriching a B2B record). To go the other way (company name → number), use corporation_search. Source: Shirabe Corporation API.

Parameters (1)

law_idstringrequired
A 13-digit Japanese corporate number (法人番号), e.g. 1234567890123.

corporation_search

Search the Japanese corporate-number registry (National Tax Agency) by company name and return matching companies, each with its 13-digit corporate number (法人番号), registered name and address, plus mandatory NTA attribution. Handles trade-name variants (㈱ / (株) / 株式会社) via normalization. Useful when an AI agent has a company name and needs to resolve its corporate number / canonical record. To go the other way (number → company), use corporation_lookup. Source: Shirabe Corporation API.

Parameters (1)

namestringrequired
A Japanese company name, e.g. 株式会社テックウェル (variants like ㈱テックウェル are accepted).
