The Rainbow Festival in Shinjuku Nichome today was short (2.5 hours), fewer than 5,000 people in world’s largest city, but there were some special moments. The portable shrine was fronted by women, but seeing the guys in fundoshi “bringing up the rear” was delightful.
I will go on a limb and say that I think it’s all about the immaculate white booties. They provide the purity that allows and nay encourages full ass exposure in a ritual that celebrates unseen gods in local wood structures, as well as farming cycles.
Is having a bubble butt a requirement for participation in carrying the shrine? The husband notices that the guy second from the right above is using belting or other under-technology to accentuate his ample assets. Would you call this a reverse push-up bra?
There were some yukatas to be seen, some androgynous yankii food sales nymphs, and a few lovely drag queens. But nothing comes close to the combo of white booties, uniform jackets, head towels, and exposed rumps.

Wish I could have made it. I’ve not seen enough bubble butt this year!
That’s a major attraction of summer festivals. Have you been to any this summer?
No, I’ve been really slack. I am going to Otsuka today but I think it’s more dancing than anything.
