numbers in urban blocks

Hello,
In Tokyo, the administrative apportionment of districts is organized and numbered in urban districts and in urban blocks. So we find addresses like "5-6-23 XYZ-ku".
In the same way as Google map allows to locate an address on a plan, is there a web site which proposes maps which give the geographical distribution of the numbering in an island or in a district?
Thanks for you informations!

Could you give an example of what you're looking for? Your question is difficult to parse.

So we find addresses like "5-6-23 XYZ-ku".

No, you don't find addresses like that - there's usually a town (machi) name, a ku name, a city name and often a prefecture name.

Hello,
I meant addresses like that :

Mr and Mrs ABCDEF
A-B-C Higashi-Shimbashi
Minato-ku, Tokyo
Japan

I would like to know if there is a web site that gives maps with blocks and the numbers. Thanks for your tips!

Google Maps.

For example, if you enter "5-12 shinbashi"

it returns

https://www.google.com/maps/search/5-12+shinbashi/@35.6630128,139.7544...

Of course, you should enter correct address. If you click the number on the map (of Google map), you will see the address on the left of the window. You can presume the address to be entered.

In the same way as Google map allows to locate an address on a plan, is there a web site which proposes maps which give the geographical distribution of the numbering in an island or in a district?

Google maps gives this information, although it may not be immediately visible to you if you don't know what you're looking for. Maybe mapion would be easier to understand?

Perhaps you could you give us an idea of what you're trying to do?

Note that addresses are not "logical", so even with a map like the one you describe, you still might have trouble. Just type the addresses into Google Maps.

Thanks a lot for your answers! that's ok with google maps, finaly.
