Time of Wickedness (1985)

Fukashi is a graduate student who left his prosperous family in Tokyo to live in a small northern coastal town, where he leads a frugal and carefree life as an employee of a harbor fish market business. After months of searching, his mother Ryoko finally found him here and tries to bond with him again. She rents a small apartment overlooking the market square and regularly comes to buy fish at Fukashi's stall. But it does not serve this.
