How much would a skateboard cost in Japan? And Where can you buy one?

Skateboards run from 2000 yen to 13000 yen on the first page of Amazon.co.jp. You could also buy one from Toys R Us (check their Japanese website for more prices). I know a junior high school student who is good enough to have a sponsor already . . . . So, I'm sure if you needed a fancier skateboard in Japan, you could find a professional-grade one.

It depends on the quality.

$10 and up . There's sporting goods store in Tokyo / Osaka . Small cities , no .

It's like 5000-10000 yen. You can buy it at a sports shop.

In Tokyo, Kanda is the go-to neighbourhood for sports equipment. There must be a skateboard shop in Kanda, even if golf clubs and skis are the usual fare.

4, maybe 5.
