The Karamon (唐門?) is a gate of Nishi Hongan-ji designated a National Treasures of Japan. It is constructed as a four-legged gate with karahafu gables of undulating curves on the front and back. The Karamon gate has a roof in the irimoya style, a style of hip roof sloping down on all four sides and integrated on two opposing sides with a gable. The roof is covered by bark shingles made from hinoki cypress. The gate dates to 1573 and was constructed early in the Momoyama period (1573 – 1614).
