Tokyo niwatsuki ikkodate (2002)

One wish every parent has is for the children to finally move out of the house and be independent. No more mooching kids. For recently retired professor Tameyama Kazuo, father of 5 married and single independent-minded daughters, one would think he'd want the same too. But alas, he wants to reunite his whole family and into the same house no less! Despite howling protests from his daughters, with a modest sum of money from his cancelled insurance policy and retirement funds in hand, Kazuo sets out to find the perfect home: posh central Tokyo location, close to the local grade school for his daughter's children, and good transportation access. Is he kidding? Sure enough, he finds the seemingly perfect dream home and moves right in with all 9 family members in tow. But not everything is what it seems for the households some surprisingly costly secrets of its own.
