Here's the new commercial for Suntory's Protein Water featuring Shota Matsuda and Shido Nakamura. It shows the two actors heading up a "slender macho" team against a "muscle macho" team. If it's not already homoerotic enough for you, Japanese netizens think that the guy dancing at the front of the "muscle macho" group is one of Japan's leading gay porn stars. The Suntory website shows some behind-the-scenes photographs where the performers have their masks off and the bloke does look like he might also be on the cover of this DVD (NSFW). Others are convinced that is is the same bloke because the shape of his nipples is identical:
