I have tried to geocode address in Japan using Nominatim, but it does not work. It only work for major city and ward. Threr is a detailed data that government provide. So could someone that is developping Nominatim apply that data for Nominatim?

That data can be used freely. It can be download from their website. There is no license. They say that; "Use these data freely, but there is no guarantee."

I placed sample data to my server (35MB). This is just a part of total data. I hope it is to be sample.

I have already asked this question at OSM Help.

I believe that much of the administrative data was imported in the meantime, so I expect that results have already improved.

In any case, Nominatim can only take house numbers from external data. The data you have here would have to be mapped in OSM.
