That is, the Qing Temple
即清寺Legend has it that it began at the beginning of the Heian period, when Kobo Daishi's nephew, Kazuhisa Enchin, enshrined a statue of Myō on the mountain behind the temple, around the current Yoshinoyama Garden, during a pilgrimage to various countries.
It is said that Minamoto Yoritomo, the great shogun who heard about the statue of Myō during the Kamakura period, ordered Hatakeyama Shigetada to build a temple at the present location, and welcomed Genyu Sojo, a former monk who had spread the teachings of Shingon in the Kanto region, to open the mountain.
The name of the temple, Izsei-ji, is derived from Shigetada's precept name in the Shingon sect, Yūsan Ryūsei Daizen Jomon.
After several ups and downs such as fires, in the Muromachi period, the temple became more and more prosperous with the arrival of Inyu Hoin, a learned monk who was said to be the second coming of Kobo Daishi on Mt. Koya, as the abbot of Chūkō.
After the Edo period, there are records of large temples built during the Keian year around the time of Shogun Iemitsu and during the Yoshimune Kyoho year, but in the Meiji fire, all but the Buddha statues, including the statue of Myo, the main shrine, were lost. It is believed that the stone Buddha and stone monuments remaining on Mt. Atago in the back mountain attracted the worship of the townspeople of Edo and the Yamabushi of the time.
Currently, the guest hall rebuilt in Meiji 38, the main hall rebuilt in Showa 14, the bell tower, and the mountain gate rebuilt in Showa 55 have been developed based on the precious purity of the Dan congregation, and the state of the past is still conveyed.
