Blue Japan Speedo Dimpled Rear

A long time ago, I found a proto-blog on a Japanese site called Yoruzu (which I can no longer find). I collected a number of shots from there of Japanese lifeguard competitions, and until Speedo Jack posted one of them recently, I'd never seen any of those photos anywhere else.

So here's part of that extensive set, my favorite group, featuring the very fine, fine rear of one lifeguard, all in blue.
