How this service works
Japanese address normalization / 日本住所正規化: accept an address with or without a postal code, parse prefecture/city/components, and use local address data for matching. A missing postal code is not inferred by this endpoint; use postal-lookup for reverse lookup. / 郵便番号の有無にかかわらず日本住所を解析し、都道府県・市区町村・構成要素を抽出してローカル住所データで照合します。このエンドポイントは郵便番号を自動補完しないため、逆引きにはpostal-lookupを使用してください。
Output
Returns structured address components extracted from the input Japanese address string, including the normalized postal code (〒 format), prefecture (都道府県), city/ward/municipality (市区町村), and the canonical full address text suitable for use in company, invoice, and contact records.
Example use cases
Invoice contact address standardization
“I have a supplier address written as '大阪府大阪市北区梅田2丁目4-9' on an invoice — can you normalize it and give me the structured postal code, prefecture, and city so I can enter it correctly into our billing system?”
Japan KYB company address parsing
“We're onboarding a Japanese company and the address they gave us is '愛知県名古屋市中村区名駅1-1-4' — please parse that into canonical address fields including the postal code and prefecture for our KYB records.”
Business card contact address cleanup
“I scanned a Japanese business card and the address field reads '神奈川県横浜市西区みなとみらい2-3-5' — normalize that into structured fields so I can save it as a clean contact entry.”
Technical details
Endpoint
POSThttps://api.jpverify.com/jp-address/normalize?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to parse or standardize a freeform Japanese address string into structured fields (postal code, prefecture, city, canonical text) for use in Japan-specific invoicing, KYB, contact management, or compliance workflows. Prefer it over generic geocoding APIs when the target locale is exclusively Japan and structured Japanese administrative divisions are required.
Side effects
- Ambiguous or partial address string may result in low-confidence or incomplete parsing
- Non-Japanese or romanized addresses may fail to parse correctly
- Unrecognized locality names may cause prefecture or city fields to be null
- Malformed input (e.g. missing city block numbers) may yield partial results
- Network or authentication errors return non-200 status codes
