Takachiho Peak, a sacred peak known as the stage of the Advent of the Heavenly Son. Because of its beautiful appearance and history, it has been popular among people as the main peak of Mt. Kirishima. At the top of the mountain, you can see the "heavenly reverse halberd" of the myth of the advent of the heavenly son. In a letter from Ryoma Sakamoto, who visited Kirishima at the end of the Edo period, it is written that he climbed the mountain with his wife Ryu.
