Who's Afraid of Wives? (1998)

Faithfully married to his wife for 25 years, Goro Mochizuki is left to live alone for three months while his wife visits their pregnant daughter in London. His two devious childhood friends, Tamotsu Kobe and Kenji Morikawa, use the chance to gain a little freedom for themselves and move in with Goro. Goro would rather have his wife home and his friends out the door, but with all the beautiful women who walk into his life every episode, he might take the opportunity to do a little flirting of his own.
