NO STREET NAME
Every profile this generator assembles reads the way Japan Post reads an address: the chome-ban-go house numbers first, then the neighbourhood, the ward or city, the prefecture, and a seven-digit postal code to close. Japan skips street names entirely — blocks are numbered from within, not along a road. Each card pairs the address with a Japanese name in romaji, a 090 mobile number and an email. Generate a set, filter by prefecture, export what you need.
All 47 prefectures, deep pools for the big ones
The filter covers all 47 prefectures. Tokyo, Osaka, Kyoto and Fukuoka carry deep city pools for heavy testing; every other region holds its capital with a zone-correct postal code in the dropdown.
Tokyo
Shinjuku, Shibuya and Minato wards: Nishi-Shinjuku, Roppongi, Akasaka. Postal codes open with 150-160.
Osaka
Kita and Chuo wards: Umeda, Namba, Shinsaibashi. Codes in the 530-542 range.
Kyoto
Nakagyo and Shimogyo wards: Kawaramachi, Karasuma. Codes start with 600-604.
Fukuoka
Hakata ward: Tenjin, Nakasu. Codes start with 812.
Every card shows its city and code, so an Osaka address never gets mistaken for a Tokyo one.
Two ways to write the same address
The Universal Postal Union's guide for Japan describes the native order as a single line that starts with the largest area and ends with the smallest — and notes that street names are not used at all. Written in romaji for Western readers, the same address can follow the familiar small-to-large order:
Both orders are legitimate — the UPU documents the Western layout explicitly. Two things still trip people up: there is no street or state line to fill, and the postal code sits between the city and country in the Western layout, not on the line above the recipient.
None of this is a convention we guessed at. It follows the addressing standard the Universal Postal Union documents for Japan, supplied by Japan Post itself.
Need a whole list? Export it
One address at a time does not help when you are seeding a test database or mocking a shipping flow. Save the profiles you like, then export the whole set as CSV or JSON in one click. Every field comes along — name, address, prefecture, postal code, phone and email — so nothing needs re-formatting downstream. No cap, no signup, no watermark.

Postal codes and the 2-17-10 problem
A Japanese postal code is seven digits with a hyphen after the third: 〒160-0022. The UPU's breakdown marks the first part as the area and district, and the code pins delivery down to the post office handling that neighbourhood. The GeoPostcodes database tracks about 143,000 of these codes across Japan.
The house numbers confuse newcomers because they are not sequential along a street. The UPU glossary chains them: a machi or cho neighbourhood divides into chome zones, chome divides into ban blocks, and ban divides into go buildings. So 2-17-10 reads as chome 2, ban 17, building 10 — and the order matters. Several buildings can share a number within a block, which is why apartment numbers get appended: 2-17-10-153 is room 153.

Use cases for test addresses
Form and QA testing — fill Japanese checkout flows with prefecture-valid, postcode-shaped profiles that pass field validation.
Localization reference — compare romaji line order against the native Japanese order before wiring address forms.
Teaching and demos — show how chome, ban and go nest inside a machi without a street name anywhere.
What these samples are — and aren't
Built for: software testing, format reference, localization QA, placeholder data.
Not for: real correspondence, identity verification, or registering for services against their terms. Generated profiles are synthetic; a correct postal-code pattern is not proof the address exists. For actual mail, confirm the address with the recipient or Japan Post's own tools.
How the samples are built: wards, postal-code ranges and line order follow the addressing standard documented by the Universal Postal Union for Japan. Data pools last reviewed September 2026.
