In summer in Japanese schools, students learn to swim in physical education class.

In the past, a ship carrying many students sank in an accident, and many children lost their lives because they could not swim.

I have heard that swimming was introduced into classes at schools all over Japan based on the reflection of that accident.

This swimsuit is modeled after one of the student swimsuits that were once widely and officially adopted in Japanese schools.

In order to avoid sensitive images, the sample was worn by a mature person.
