Constructed during the Tokugawa Shogunate, the headquarters of the Pure Land sect is highly representative of modern authentic large-scale Buddhist architecture and is highly significant from a cultural history perspective for the great influence that it has had on Japanese culture, which led the monastery to be designated a National Treasure in 2002 along with the sammon gate.
徳川幕府の造営になる、近世の本格的かつ大規模な仏教建築の代表例であり、日本文化に多大な影響を与えてきた浄土宗の本山寺院の建築としての文化史的意義も高いことから、2002年、三門とともに国宝に指定されている。
