Wards are divided into chou (町) (though sometimes the name doesn't include the word chou). Sometimes the chou are divided into choume (丁目), which are numbered divisions of a chou. Then the blocks are numbered and, at the lowest level, the building has a number. Finally comes the room or apartment number. For an apartment, the name of the apartment building is often included. However, it is not necessary for mail. It is, however, a convenience for visitors who ask for directions.
The buildings within a block are either numbered in the order that they were built, so they jump all around, or numbered in clockwise order around the block. In this clockwise numbering there is sometimes skipping of several numbers for later assignment, where future construction between existing buildings is possible.

For addresses in large cities (Yokohama, for example) many people omit the larger division (Kanagawa-ken, in the case of Yokohama).
The ken, to, etc., can always be omitted if the postal code is correct. The city name should be capable of omission then too, but that isn't ordinarily done.
There can't be a ku name directly below a fu (since Kyoto and Osaka are both shi), but this is a technicality which the Post Office is sure to overlook. In addition to gun, there are shichou (市町) below Tokyo which contain chou and son (which would normally be under gun). (There are also shichou below Hokkaido, but they contain shi and gun as would be expected.)
As far as the address after shi, ku, machi/chou or mura/son is concerned, trying to reach a consensus on what is what may well be an exercise in hair-splitting.
There's a problem with duplicate terminology where the part about chou (under shi, ku, machi/chou or mura/son) is concerned. There doesn't seem to be a consistent term for these smaller divisions (they seem to be called shigaichi (市外地) in heavily populated areas, and in the country they are often called aza (字), and sometimes an aza is divided into several division names.)
The choume part is not present in many addresses, and in this case the address may either end in banchi (番地) or contain ban and gou. Banchi/ban may be single blocks, parts of blocks, or split into several blocks. Gou may be single buildings, complexes of several buildings, or parts of compound buildings. Some addresses contain the specification mubanchi (無番地) ("no banchi").
Extremely detailed maps are published for all urban areas. Anyone who can read Japanese may be able to identify any address within a 2 or 3 minute walk. The most detailed bilingual ones are not as good. Of course even a bilingual map as detailed as the Japanese ones would still be very hard for foreigners to use, because the signs are in Japanese only.
All postal codes conform to a 7 digit format XXX-XXXX. This was
introduced by Japan Post on February 2, 1998. It is theoretically
possible to put the postal code followed by the address from
choume "downwards", although in some areas the postal code may go
over choume boundaries. Before the introduction of the 3-4
system country areas and large city areas had sub-codes, eg. 316-0002
or 150-0001, but now all codes comply. The large area encompassed by
100 (central Tokyo) is now split into up to 9999 sub-areas. A book
was put out so people could look up the new code from the old address.
