Sounds like you had fun. I love Osu and go there as often as I can, which tends to be at least once every few months.

You have to be careful with those ¥100 shops. Cheap things (cheap in quality too) but ¥100 does add up quickly. Everyone I know (Japanese and expat, both) has spent hundreds of dollars on worthless things from ¥100 shops.

Oy—How I wish for bitcoin at the konbini. I don't think that's anything we will be seeing here for a very long time.

Anyway, good post. I enjoyed reading!
