For Itsuo Kandatsu, cooking three meals a day is a task he performs for his wheelchair-using mother and disabled brother. But the 49-year-old Tokyo resident isn't a house husband.

He used to work for an insurance company. He quit to become a freelance salesman in 2003 so he could take better care of his 81-year-old mother in Arakawa Ward.

"I couldn't help my mother while working full time at the same time," he said.
