One of the best parts of summer in Japan is men in yukata, a light-weight summer kimono. The funniest thing is that when young guys wear them in Tokyo, typically they choose dark and understated ones like the one worn by Tamaki Hiroshi above.
It’s a rare moment for the Japanese peacocks to choose restraint, and the girls in summer wear the most garish colors and patterns on their yukata. At least, as you see in Tamaki-sama’s photo, he hasn’t eschewed the fancy hair-do and extraneous jewelry (including ankle bracelet?!).
