A cheesecake moment on the IotD? Nope. What you're looking at there isn't what you think you're looking at. It's a new trend in Tokyo: the booty there is not actual, it's a DESIGN. Probably silkscreened.
How much of a trend isn't certain, but
this page is where the pic came from, and IT says this is a trend. I read it on the Intarweb so it MUST be true!
There are four other examples on that page.
Yet another bit of Japanese culture that I don't understand. But it's interesting.
