Doesn't even raise a blip on my weird-o-meter.
Last time I was in Tokyo I saw more than one Japanese Elvis, Japanese pre-US invasion Beatles, Japanese Sgt Peppers Beatles, random fat guys wandering around in Onesey PJs and a dude in a trenchcoat flashing folks wearing a purple fuzzy cod piece with spikes. All that was going on day time , work week, middle of winter. Japanese folks has a serious costume fetish. Worth it to walk Harajuku and Shibuya to see the chicks going balls deep into Victorian Goth and Barbie's Summertime Beach Party.
