Since launching two weeks ago on Rakuten, a major Japanese web shopping mall, the Wishroom shop has sold over 300 men's bras for 2,800 yen ($30) each. The shop also stocks men's panties, as well as lingerie for women.

"I like this tight feeling. It feels good," Wishroom representative Masayuki Tsuchiya told Reuters as he modeled the bra, which can be worn discreetly under men's clothing.
