Kirishima Onsen held deep within nature in the mountains has been said to be called "Kirishima" because the mountains in the area appeared to look like islands among the thick sea of mist surrounding them. After having enjoyed hiking in the Kirishima mountains where there is also a national park, how about trying to relaxingly heal the fatigue of the trip at the hot spring hotel located within the mountains? The nationwide-famous Kirishima Onsen is also called a heaven-descended hot spring which has been visited by the likes of Saigo Takamori and Sakamoto Ryoma, including the feudal lords of the Satsuma Clan. People from the old days loved hot springs, as well!
