Can't wait to go and soak in an onsen during the christmas holiday. Anyone going on a trip to Japan for christmas as well? My Japanese friend is studying biotechnology at Tokyo University. He loves kickboxing. He's lucky because his professor grants permission to use the ring at university. He also joined a gym. The gym membership agreement grants you access to the swimming pool, sauna and steam room as well as the gym. It's well worth it for the broad range of facilities you can use.
