"People around us tell us that we're like meoto-manzai (stand up comedians). We're always surrounded by laughter," says Atsuko Nonogaki Planeta, 43.
"We're talking all the time. I never get bored," Paolo Planeta, from Genoa, Italy, adds.
Paolo, 37, and Atsuko met in Tokyo at a networking party in September 2006. They dated for just over a year, and got married in November 2007.
