Sort of. They get the guys to do all the icky stuff.
The whole article's a real leg-slapper, but can be best summed up with this gem of a title:
Hot Women Serving Cold Fish Make for Raw Feelings in Tokyo: Japan's First Sushi Restaurant Staffed by Female Chefs Has Traditionalists Carping.
Google "hot women", "cold fish", "raw feelings in Tokyo" and "first sushi" with your Safe Search turned off. I double dog dare you. I carp you.
In fact, skip ALL of that and just search "Nadeshico", the restaurant's namesake (translates literally to "ideal woman"). NSFW.
The centuries-old official line regarding gender disparity in sushi chefdom is that women have naturally warmer hands than men, which is detrimental to the handling of spanking-fresh raw fish. On top of that, wimmen are covered in girly sh*t, like perfume and cosmetics, that could effect the purity of the fish.
Things that also effect the purity of fish: Being black, white, Latin, non-Japanese Asian or any mix thereof. They also hate kittens, gays, big people, little people, cripples, vampires, zombies, the homeless and Bieber fans. Oh, and chicks over 25:
Kazuya Nishikiori, the middle-aged owner of Nadeshico, says he wanted to create a new model for working women in Japan. But he later explains he'll only hire women who are between the ages of 18 and 25 to work behind the counter. "After all, our slogan is 'fresh and kawaii,"' he explains, invoking the ubiquitous word for "cute." "If someone wanted to work here and was 30, I'd put her in the back." [WSJ]
On the upside, if the fish-eating pervs are all in one spot, they'll be easier to avoid.
People, for the love of God, don't blame pandas. Or cosplay. They can be used for the forces of good.
