In Perfect Days, Hirayama (Koji Yakusho) is a bathroom cleaner. He starts his day early, gets a coffee from the vending machine, pops a classic rock tape into the stereo, and drives his van to various public restrooms, where he gets to work. He scrubs and tidies the sink meticulously. The various parts of a bidet are wiped. He uses a small mirror to check the underside of a toilet to make sure it’s sparkling in places no one will ever see.
