Buying apartment in inaka

Hi forum, thanks for your help in advance.

I'd like to buy an apartment for cash in a small town about 1,5hrs by Shinkansen from he big city.
My Japanese is basic and as expected nobody in the agency speaks English.
Anybody was in the same situation? Or knows smbd who was?
I understand that they want me to appoint an agent and to get an intermediary company for escrow. Anyone can recommend anyone who helps foreigners in is situations? My google search points me to Tokyo real estate agencies and I'm not after anything that fancy really.
Thanks in advance.

1.5 hours by shinkansen from a big city basically includes the majority of Japan, so first step would be to settle on an area. Then you can start looking for local agents to help you in your search. However, if you don't have the language ability to deal directly with them then it may be btter to go via a Tokyo agent as an intermediary. Nothing too fancy about that as Tokyo is where you'd expect the agents to be considering there is not a big market for foreigners looking to buy real estate in Japan.
