Sampei (8) and a bunch of other boys wearing only loin-cloths go swimming. As Sampei begins taking his clothes off, he discovers he forgot his loin-cloth and pulls his pants back up. The other boys tell him he doesn't need one so he takes his clothes off and walks toward the water. He then changes his mind and puts his clothes back on and says "I'll watch your clothes." Full frontal and rear nudity.
One scene is starting with a close-up of Daigoro's bare bottom, then showing him from a distance. It's not quite clear what he's doing, probably cleaning something by using his pants.
The young boy (Jonathan Chang, 8) is standing on a chair wearing nothing but a towel. As the boy stretches out to reach something, the towel falls off revealing his penis as he tries to grab the towel again.
In a flashback scene, a young boy is laying in bed when a man removed the cover and is trying to touch him under his pyjamas, but he escapes before anything happens.
