Natsumi-san, those motorcycles look like what were marketed here as Honda "Trail 50"'s; it is wonderful that in Japan you can make them street legal! Here in the USA, riding has gotten extremely dangerous because of the traffic and so many people who are not good drivers. I guess even in Japan you have to be careful (we saw a very bad wreck back in May on the Toll Road near Fukushima), but at least the cars are smaller. Thank you for posting this!
