Why do Japanese actresses like to take pictures in swimsuits?

This can be said to be a style. The swimsuit photos taken by female stars are popular with the public, so they are taken. It can be said that Japan likes watching them, so it took pictures. It seems that they also like girls to wear maid clothes and princess skirts to be cute. Personally, I think it's because swimsuits can show the youthful vitality and beauty of girls and make people relax. Due to the pressure of life in Japan, many office workers feel relaxed when they see beautiful and pure girls relaxing themselves and showing their physical beauty. This is also a way to relieve stress.
