Jun 1980 one on netflix

Jun has come to Tokyo from his family home, an island which resembles a ship. He works in a machine shop and is attempting to develop a career as a cartoonist in his spare time. When he travels around the town by subway, he has grown into the habit of groping female passengers in a sexual way. They never denounce him, and many seem to respond very favorably, moaning in apparent ecstasy. However, when his girlfriend sees him doing this, she denounces him to the police.
