Japanese men worry about 'ageing odour'

Japanese men are worrying about more than mere sweat as summer temperatures rise: talk of body odor caused by ageing is adding to anxiety in a land that prizes being squeaky clean, Reuters reports.

Shiseido Research Centre, a laboratory affiliated with Japanese cosmetics maker Shiseido Co Ltd, sparked the trend to anti-odor products for older men when it discovered eight years ago a substance that it named "kareishu", or ageing odor.

The lab identified nonenal, a type of fatty acid, as the cause, saying unsaturated fatty acids and oxidative decomposition increase from around 40 years of age.

Being Japan, it has also sparked a range of new products, from odor-eating suits to special chewing gum.

"My wife tells me that I stink," said company manager Atsushi Asami, 47, interviewed on a typically hot and humid Tokyo street. "I am concerned about ageing odor and know there are anti-ageing odor products, but have not bought them myself."

An on-line survey by CBIC Corp., a Tokyo-based company that sells deodorant products, found that 89 percent of 700 Japanese women in their 20s and 30s found men smelly in commuter trains.

A discount menswear chain last year started selling 'deodorant suits' as well as anti-odor shirts and socks.

"More Japanese men are becoming concerned about their smell and so the need for anti-body odor products is growing," said company spokesman Yuriko Moriya.

The 61,950 yen ($576) suits, are laced with disinfectants that absorb and break down substances that produce ageing odor and the smell of sweat. Sales this year have doubled from the same time last year.

Gomi says lifestyle changes are probably a better way to fight the smell, since avoiding stress and excessive eating and drinking help ease the problem.

But he added: "Being called 'smelly' can be damaging to our personality. In that sense, deodorant products can be used as a confidence booster."

Do men really get smellier as they age? Or is this just a gimmick to prise money from the sweaty hands of wealthier, insecure older men? Would you wear a deo-suit?
