Skiing on a skateboard? I've got to admire his balance. I'd be flat on my face so fast...
Everything says "Suteteko is Japanese men's long drawers. Middle-aged and old men usually wear a suteteko above underpants to prevent sweat from wetting their trousers. It is particularly effective in hot and humid summer. In informal households, men may be seen in an undershirt and a suteteko watching TV or working in the yard."
ステテコ(suteteko) = "Japanese summer longjohns"
As near as I can figure, the key point is the wicking action that disperses the sweat—not that it's ever going to evaporate in the hot, sticky Japanese summer—prevents you from leaving blotches wherever you sit, etc.
Blogged at Tokyo Times: "could 70 actually be the new 40 in Japan?"
The author got it from (emphasis mine) FG forums: 2007年は誰もが外人犯罪の標的になる! 徹底的に外人犯罪を追い詰めよう!
外人犯罪(gaijin hanzai) = "all those filthy foreigners fouling Nippon"
↑ I hope that the poster is being sarcastic. I am so tired of Japanese media toeing the National Police Agency line on nasty foreigners—especially when the NPA's own statistics prove the 99% of all crimes other than overstaying a visa are committed by JAPANESE.
渡邉實夫(WATANABE Jitsuo) is his name. He studied electrical engineering, but worked in television. He promised to take me skiing next season.
