Ahh, the onsen . Arguably one of the greatest Japanese experiences, the Japanese bath can be a tricky adventure. If you remember only two Japanese characters, make sure they are the ones for male (男) and female (女). Written on the curtains at the entrance, a misreading could lead to loud screams or cheers of joy. Once inside, there are no bathing suits, underwear or bath towels. The small towel is for washing. If you want to feel like a veteran, try placing the small towel on your head while relaxing in the bath.
