This planet is full of spectacular natural beauty. You'll find some of it at Onoaida Onsen, which is famous for its natural, bubbling waters.
If you're staying a while in Yakushima, Onoaida Onsen is a good place to kick off your sightseeing. This naturally heated water source is one of many attractions worth seeing here. Yakusugi Land, Mt. Mocchomudake, and Yakushima Botanical Research Park are also ready to be explored close by.
