During development testing or data mockups, you often need fake data that strictly follows Japanese address formatting. Based on Japan's administrative division system, this tool randomly generates complete address strings containing postal codes (郵便番号), prefectures, municipalities, town areas, and block numbers. The format strictly adheres to the 7-digit postal code standard (〒XXX-XXXX) and the hierarchical structure of 'Prefecture → Municipality → Town Area → Block Number'.
Can the generated addresses be used for real mail via Japan Post?
No. All addresses are fake data, and the block numbers are randomly combined. They are strictly for testing purposes only.
What do 'Chome', 'Ban', and 'Go' mean in the address structure?
This is Japan's unique address numbering system: Chome (city district) → Ban (block number) → Go (specific building number). For example, '1-chome 9-ban 1-go' refers to the 1st building in the 9th block of the 1st district.
Please do not use these generated addresses for official registrations, real logistics, or actual mail. When generating in bulk, we recommend waiting at least 5 seconds between requests to avoid server overload. The system does not store any of your generation records.
The 'town area' (町域) in Japanese addresses can be written in multiple ways (e.g., Romaji, Kanji, abbreviations). For testing purposes, we recommend consistently using the full Kanji notation generated by this tool. Typical example: Click 'Generate' → Output: '〒530-0001 大阪府大阪市北区梅田一丁目1番1号'.
