Arihiro Fujita and Kimiyo Fujita, owners of the award-winning Takasagoya Pork Shop in Tokyo's Tsukishima, know their pork. These two 65-year-olds also know what makes a relationship work. They've been married and working together for 40 years -- without, they claim, even one argument.

Arihiro-san: You can't argue when you're naked and in a big tub of hot water! So we bathe together every night and since we are relaxed, it is the perfect time to discuss the mistakes of that day, plan the next and show our appreciation for each other. I say, Sorry for getting mad today. She says, OK, don't worry, honey.

Kimiyo-san: Men need more support than women, so if the wife is smart enough to recognize this, everything goes smoothly and the whole family is happy.
