For RC stuff, try Kunii mokei. Kunii san is a nice guy but he doesn't have
much of an interest in cars, although he has a few cars in his shop.

To get there is pretty easy. Do you know Aizumachi? Turn off Rt 289 into
Aizumachi, after you have gone under the train tracks  turn left down the
second narrow road, and you can see his shop on the left.

The main shop for this area if you are interested in cars if called Silver
Wing (0249-43-8700) but is a little far from Shirakawa. in Koriyama go past
the station take a left and through the big tunnel that goes under the
tracks, this is the road for the culture center I think, you will find the
shop on the right, just before the bridge.

You live in Shirakawa? Who are you? I must know you unless you work at
British Hills or Geos

If you want to race nitro cars there is a track in Bobata, and a track in
Shiobara. Bobata is cheapest, at 800 yen per day.
