Look up the address (prefecture, city, town) for a 7-digit Japanese postal code, from Japan Post data. Accepts forms like 1000001, 100-0001 or 〒100-0001. One code can cover several towns; all are returned. `town_detail` holds the parenthesized part as written by Japan Post (e.g. chome ranges or building floors).

Find Japanese postal codes by prefecture, city and (optionally) part of the town name, from Japan Post data. The city must be the full municipality name (e.g. 札幌市中央区, 新宿区); the county name may be omitted. With `office_name`, searches business-specific codes (大口事業所個別番号) of businesses in that city by name instead.

Split a Japanese address into prefecture, city, town and the rest (block numbers, building), matching Japan Post's address data, and return candidate postal codes. Absorbs full/half-width, spacing, kanji vs. arabic numerals, ヶ/ケ and omitted county names; fills in the prefecture when the city is unique. Does NOT verify block/house numbers and has no coordinates. `level` tells how far the match went: 0 = nothing matched, 1 = prefecture only (see `city_candidates` if the city name is ambiguous), 2 = city matched but not the town (`postal_codes` are city-wide candidates), 3 = town matched. `address` and `municipality_code` are null below level 2. flags: `partial` (level below 3), `ambiguous` (several city or postal code candidates — ask the user or show all). / 住所を都道府県・市区町村・町域・残り（番地・建物名など）に分け、郵便番号の候補を返す（日本郵便のデータにあてはめる）。番地が実在するかの確認と緯度・経度はない。level：0＝わからない、1＝都道府県まで、2＝市区町村まで（町域はわからない）、3＝町域まで。

The check digit (first digit) is verified first; a wrong check digit is reported as an input error. flags: `closed` (the registry record is closed — tell the user), `excluded_from_search`, `not_found`.

Matching in the middle of a name and furigana search are not supported. flags: `truncated`, `exact_match_only` (too many names start with the input; only exact matches returned), `not_found`. Returns up to 100 matches (`total`, `returned`, `truncated`) with corporate number, name, prefecture, city and `is_closed` (registry record closed); use lookup_corporate_number for details. Corporations marked as excluded from search on the NTA site are not included. / 名前の先頭から合う法人を探す（前方一致）。株式会社などの言葉は前後どちらにあっても無視し、全角・半角や空白の違いも吸収する。名前の途中からの検索とフリガナの検索はできない。最大100件。詳しい情報は lookup_corporate_number で。国税庁のサイトで検索対象除外の法人は入っていない。
