My .02,

Nominatim is extremely Euro (and especially British) centric in its
view of the world. While it does the job, it doesn't even do an ideal
job in the United States, which is a country that shares the same

My hope for OSM geocoding long term is for there to be greater
diversity in geocoders, such as Photon (which uses parts of Nominatim)
and Pelias, which doesn't share any code with Nominatim.

It might make a lot more sense, based on the differences not only in
language but also in addressing systems, for the Japanese community to
put their efforts into a new geocoder which specifically addresses
their needs.
