The predecessor of Tenryuji Temple is said to be Hossenshi Temple in Tōtōmi Province (present-day Shizuoka Prefecture), a historically significant Soto Zen Buddhist temple with orthodox lineage. When Ieyasu Tokugawa entered Edo, its predecessor Hossenshi Temple was relocated to the vicinity of Ushigome-machi in Shinjuku Ward and renamed Tenryuji. After being destroyed in the Tenwa Fire, it was moved to its current location. The temple is situated near Shinjuku Station, adjacent to Koshu Kaido and Meiji-dori, surrounded not only by constant traffic noise but also by towering skyscrapers. The design plan aimed to create a contrast: despite the urban environment, visitors entering the premises would immediately sense a shift in atmosphere, feeling the weight of history and tranquility. The architecture employs traditional Zen Buddhist temple complex styles, with meticulous details to evoke reverence. A sloped courtyard between the main hall (hondo) and the kuri (monastic living quarters) allows worshippers using the semi-basement guest hall to escape the surrounding bustle and reconnect with nature.
