This Japanese custom is probably going to make a ton of sense to all of the shower people out there. In Japan, it's frowned upon to take a bath while you're still dirty. This means that it's traditional for people to take a shower and get clean and rid of debris before relaxing with a warm bath. We totally get this one, and it doesn't really seem all that strange at all.
In Japan, soaking in a bath is considered more of a relaxation activity than an actual way to get clean. This is definitely one tradition we could totally get behind.
