To mourn the loss of Enshu Kobori, lord of Komuro Castle and considered one of Japan's three greatest tea masters along with Sen no Rikyu and Oribe Furuta, the second lord of the castle, Sokei invited the monk Enkei from Daitokuji Temple in Kyoto in the early Edo period and founded a temple of the Daitokuji School of the Rinzai sect. This temple was named "Omi Kosogo-an" after the Kosogo-an built by Enshu at Daitoku-ji Temple in Kyoto. Initially, the temple was a family temple of the Kobori family, but declined after the Kobori family was exiled in the late Edo period (1603-1868) and fell into disrepair after the Meiji Restoration. However, in 1965, the temple was rebuilt by Sadayasu Kobori, and the "Enshu-style" garden was repaired and maintained at the same time. The garden includes a simple stone karesansui (dry landscape garden) to the south of the main hall and a pond garden facing east, designated as a place of scenic beauty by the prefecture. These gardens are designed to take advantage of the natural topography and are said to have been modeled after the Eight Views of Omi, and provide beautiful scenery with azaleas in spring and autumnal hagi (Japanese bush clovers) in fall. However, they are not open for viewing on November 16 and 17 due to the Kaisan-no-Momorial Memorial Service.
