I have toured by bike all around Japan for 10 years.
If you want to get informations about touring Japan, please check out my site "WADACHI - Enjoy cycling and drinking around Japan! - (www.geocities.jp/wadachi294/) " (It has tips and trouvelogues), or please discuss with me. I am not so good at English, so please forgive my impolite English.
I hope we can have lot of interesting discussions in this forum.
