Choshoji is a three-storied, Irimoya-zukuri temple building with a thatched roof. The austere garden of the temple contains an ancient tree called Bunjibai, surrounded by moss and landscaped stones and rockeries. The interior of the temple was made by the Tang dynasty method, and there is a high Tang dynasty Sumidan in front of the central rear wall, and a side Buddhist altar protruding to the back. The exterior features are also Tang-like. The date of construction is unknown, but it is thought to be during the Genroku era 1688-1704. It was once a magnificent building, though now in need of repair, but remains value as a ancient Zen Buddhist temple, belonging to the Rinzai Myoshinji sect.
