Why would Japan make a video where a young women dressed as sailors/office workers/students must use their outfits to swim after falling into a pool? Dude, I don't know, it's Japan. This doesn't even register on the fetishometer over there. There are Japanese guys who can't get off unless they see an animé schoolgirl violated by horny vines in an evil forest, so it's not like a girl swimming in the water is gonna move the needle. Not unless there are giant squid and sperm whales getting involved.
