π’lookup_calendar(date, categories)
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).
Input Schema
{
"type": "object",
"properties": {
"date": {
"type": "string",
"description": "Target date in YYYY-MM-DD (between 1873-01-01 and 2100-12-31)."
},
"categories": {
"type": "array",
"items": {
"type": "string"
},
"description": "Optional purpose categories to score (e.g. marriage, funeral, groundbreaking). Omit to return all available categories."
}
},
"required": [
"date"
],
"additionalProperties": false
}π’normalize_japanese_address(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.
Input Schema
{
"type": "object",
"properties": {
"address": {
"type": "string",
"description": "A raw Japanese address string (may include postal code, building, floor)."
}
},
"required": [
"address"
],
"additionalProperties": false
}π’split_japanese_name(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.
Input Schema
{
"type": "object",
"properties": {
"name": {
"type": "string",
"description": "A Japanese personal name, e.g. ε±±η°θ―δ»."
}
},
"required": [
"name"
],
"additionalProperties": false
}π’corporation_lookup(law_id)
Look up a Japanese company by its 13-digit corporate number (ζ³δΊΊηͺε·) 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 β number), use corporation_search. Source: Shirabe Corporation API.
Input Schema
{
"type": "object",
"properties": {
"law_id": {
"type": "string",
"description": "A 13-digit Japanese corporate number (ζ³δΊΊηͺε·), e.g. 1234567890123."
}
},
"required": [
"law_id"
],
"additionalProperties": false
}π’corporation_search(name)
Search the Japanese corporate-number registry (National Tax Agency) by company name and return matching companies, each with its 13-digit corporate number (ζ³δΊΊηͺε·), registered name and address, plus mandatory NTA attribution. Handles trade-name variants (γ± / (ζ ͺ) / ζ ͺεΌδΌη€Ύ) 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 β company), use corporation_lookup. Source: Shirabe Corporation API.
