Bike travel is very interesting in Japan. I had one experience(used V Strom 250). 東京→足利(栃木)→榛名山(群馬)→諏訪湖(長野)→河口湖(山梨)→伊豆→東京. GUNMA, NAGANO landscape is so great. Venus line is very popular of biker. Very comfortable when I driving in Nagano. When I traveling days, the Light festival is opening in Japan. あしかがフラワーパーク and 伊豆ぐらんぱる公園 were amazing for me.
