Check out their Golden Week tour around the Kii peninsular.
Have only ridden with this crew once and would love to do some more rides with them.
Check out their website too. HERE….an international group of cyclists, riding mostly in and around Tokyo, linking rivers, parks and bike paths to maximize greenery and minimize contact with taxi doors. Membership is free and new members are always welcome. Thee like to look upon themselves as a sociable group of regulars at a bar, except the bar’s always in a different location and the regulars are more fit than most, as they have had to cycle 40km or so to get there.
On facebook as well.
