Whose role is doing it to do housework? 

I'd like to say that it's a robot's one but Japanese technology hasn't been advanced enough yet. haha (Been is past tense, but you're referring to the future, so it's unneeded.)

This is the a (The would mean that it's the ONLY topic they talk about.) topic that my parents have argued about since they got married. "A husband works hard to earn money to support all his family and a wife does all the housework at home." The idea was common sense in my grandparents' generation in Japan. That's why middle-aged people still have such a stereotype, because of their parents. Even young people tend to expect girls to have good skills of cooking and cleaning. Lately, the number of double-income households has been increasing. So, I guess that's the situation, which where they have to share housework.

According to my Asian female friends, it's a maid's role to do household chores because they think that a wife should focus on working or taking care of her children. As it costs a lot to hire a maid in Japan, I have never come came up with the idea and I was really surprised at the culture gap. But it's not a bad option if only people can afford it because everybody in the family will be able to concentrate on what they want to do and nobody won't will feel stress about housework anymore.

I'm curious how foreign marriage couples divide the chores. I've stayed with Canadian and Australian families before. The Dads seem to be in charge of lawn mowing and the BBQ at the weekend at least.

This is incredible, only a few mistakes, and small ones at that. I had to really search for a few of them!
