If the intense buzz in Japan is anything to go by, the film has a good chance of winning. But why is this story, in which Yakusho's character Hirayama devotes more than half his screen time to cleaning public park toilets, so riveting? The reason is an enigma, like a conversation with a Zen Buddhist priest that leaves the interlocutor full of questions but infused with a strange serenity. If you have never been inside a Japanese public toilet, the film will be a revelation. Equipped with diaper-changing tables and makeup nooks, warmed seats, electronic bidets and automated basins that hands never need to touch, they are, quite often, sanctums of peace and hygiene. This was especially so during the COVID-19 pandemic, when the ground-floor toilets of many closed office buildings remained open to anyone who wished to use them.
