Example

Example: a Fukuoka flat’s address in English for a bank form back home

Someone living in Fukuoka needs their home address in English for a bank account in their own country. The address on the lease, fictitious here, is 〒812-0011 福岡県福岡市博多区博多駅前二丁目14番7号 サニーハイツ博多305号室: kanji numerals and a building name in katakana.

  1. Pasted as it is, it comes back as “Room 305 サニーハイツ博多, 2-14-7 Hakataeki Mae, Hakata-ku, Fukuoka-shi, Fukuoka 812-0011, Japan”, with a note that the building name is still in Japanese.
  2. 二丁目14番7号 has become 2-14-7, and the town, Hakataeki Mae, is spelled from Japan Post’s data for 812-0011 rather than guessed from the kanji.
  3. The entrance sign gives the building’s English name, Sunny Heights Hakata, so the address is typed again as 〒812-0011 福岡県福岡市博多区博多駅前2-14-7 Sunny Heights Hakata 305; the last 305 is the room.
Form field What goes in
Address line 1 2-14-7 Hakataeki Mae
Address line 2 Room 305 Sunny Heights Hakata
City Hakata-ku, Fukuoka-shi
State / Prefecture Fukuoka
ZIP / Postal code 812-0011
Country Japan

One line to paste, Room 305 Sunny Heights Hakata, 2-14-7 Hakataeki Mae, Hakata-ku, Fukuoka-shi, Fukuoka 812-0011, Japan, and each field for the form. Fukuoka is divided into wards, and the ward comes before the city, which is why City reads Hakata-ku, Fukuoka-shi.

How it works

  1. Paste or type the address in Japanese with its 7-digit postcode, e.g. 〒150-0002 東京都渋谷区渋谷2丁目21-1.
  2. Type the building name in English letters if it has one (Shibuya Hikarie, Park House); the floor and room can stay as 11階 or 203号室.
  3. The English address appears on one line, followed by each field: Address line 1, Address line 2, City, State / Prefecture, ZIP and Country.
  4. Copy the line or the fields into the form. Several addresses, separated by a blank line, are converted at once.

Frequently asked questions

Where does the English spelling come from?
From Japan Post’s romanised postcode data, which gives the official spelling of every prefecture, municipality and town for each postcode. The tool finds the town your address names under its postcode and turns 丁目・番地・号 into numbers with hyphens, so no kanji has to be guessed.
Why is the postcode needed?
Because it decides the spelling: the same kanji can be read differently in different places, and the postcode points to exactly one entry in Japan Post’s data. Postcodes given to individual large businesses are not in that data.
Why is my building name still in Japanese?
Because most building names are loanwords that cannot be spelled back from kana: パークハウス is "Park House", not "Pakuhausu". Type the building’s own English name as it appears on its sign or website.
In what order should the parts go?
English addresses go from smallest to largest: room and building, then street numbers and town, then city, prefecture, postcode and country — the reverse of Japanese. The one-line version is already in that order.
What do the numbers in 2-14-7 mean?
Chōme, banchi and gō: 2 is the chōme, the district within the town; 14 the block; 7 the building. 二丁目14番7号, 2丁目14-7 and 2-14-7 all come out as 2-14-7, with kanji numerals turned into figures.
Where do the room and the floor go?
In Address line 2, before the building name: Room 305 Sunny Heights Hakata. Type the room as 305号室 or as a bare number after the building name; a floor typed as 3階 or 3F comes out as 3F.
Is my address sent anywhere?
No. The page downloads only the small part of Japan Post’s data that covers your postcode’s first three digits; the address itself never leaves your device.
