Finding your way in Japan is very difficult. Address are very long and complicated.

The Japanese addressing system is used to identify a specific location in Japan.

Address elements
The system, based on areas, starts from the biggest division, prefectures. They are suffixed with to (都, 'capital'), for Tokyo, fu (府, 'urban prefecture') for Osaka and Kyoto, do (道, 'circuit') for Hokkaid? and ken (県, 'prefecture') for the rest. Conventionally, the cities of Tokyo, Osaka and Kyoto are almost always referenced without to or fu, while Hokkaido is always with do; without it, Hokkai means simply North Sea.

Prefectures are then divided into shi (市, 'city') and gun (郡, 'district'). Unlike countries such as the US, cities belong directly to prefectures, while towns and villages are under districts. Big cities are usually divided into ku (区, 'ward'), which are in turn are divided into machi and cho (both written 町, 'town'). Rural districts are subdivided into mura (村, 'village').

The final three elements of the address are the city district (chome 丁目), the city block (banchi 番地) and finally the house number (ban 番). As these are all numbers, they are usually simply written as a string, 1-2-3, starting with the ch?me and ending in the ban. In sparsely populated rural areas, one or more of these may be missing, with some addresses having only the ban. In urban apartment buildings, on the other hand, it is not unusual to add the apartment number as a fourth element.

It is worth noting that street names are not used in postal addresses, and that the numbers in the address are usually assigned by order of construction, meaning that especially in older areas of the city they will not run in linear order.

In addition to the address itself, all locations in Japan have a postal code. After the reform of 1998, this is a seven-digit number written in the format 〒 DDD-DDDD, where the symbol 〒 (yubin) means 'post code'.

Address order
In Japanese, the address is written in order from largest unit to smallest, with the addressee's name last of all. For example, the address of the Apple Store in Ginza, Tokyo is:

〒104-0061
東京都中央区銀座3-5-12
サヱグサビル本館
Apple Store
However, the order is usually reversed when writing in Roman letters, to better suit Western conventions. The format recommended by Japan Post is:

Apple Store
Sayegusa Honkan
5-12, Ginza 3-Chome,
Chuo-ku, Tokyo 104-0061
where Tokyo is a prefecture, Chuo-ku is a special ward, 3-Chome Ginza is the name of a city district, 5-12 is the city block and building number, and Sayegasa Honkan is the name of the building at which the store resides. In practice, it is common for the ch?me to be prepended as in Japanese, resulting in the somewhat shorter

Apple Store
Sayegusa Honkan
3-5-12 Chuo-ku
Tokyo 104-0061
For historical reasons, names quite frequently conflict. The names of many prefectures in Japan are the same as old name of those regions; e.g. Gifu prefecture for Gifu province. In Hokkaido many place names are found the same as names in the rest of Japan, largely because people in Hokkaido are offspring of immigrants from mainland Japan. Also historians note that there are significant similarities in place names between places in Kinki region and ones in northern Kyushu.

History
The current scheme was established after World War II with slight modification of scheme used since the Meiji era.
