Japan is made up of four islands.http://www.lonelyplanet.com/maps/asia/japan/Northwardly,HOKKAIDO,HONSHU,SHIKOKU,and KYUSYU.
Yamaguchi is in HONSHU,which is largest iland.Also,Tokyo,Kyoto,Osaka are in it.
Sopporo is in HOKKAIDO .Because Hokkaido is a beautiful, vast place, it is popular among riders. But Hokkaido is cold, because of the snow travelling of motorcycles is impossible in winter.
SHIKOKU is known very religious land.Pilgrims come round the templesto find, discover, or recall themselves.In Kochi prefecture in Shikoku ,best wave suitable for surfing stands most in Japan.
KYUSYU is located in the west most in this four. Kyusyu is mountainous. If you like winding road, I recommend Kyushu without question .Japan's most active volcano, Mt Aso at 1,591 m, is on Kyusyu. When there is not outbreak of the volcanicity gas, you can look at the crater.
