A huge temple with a normal tile roofing and an East Asian hip-and-gable roof.
The interior is as large as 1,000 tatami mats, hence its other name Senjo-kaku— 1,000 mats palace—but actually there are only 857 tatami mats.
It was built in 1587 as a sutra library by order of Hideyoshi Toyotomi (1537-1598), the top samurai and ruler of Japan at that time.
Construction work started in 1598, but construction halted 1598 with the death of Hideyoshi Toyotomi, and it remains unfinished to this day.
Since the building was not completed, there are almost no walls inside, and the thick pillars and beams are exposed, giving the building a strange powerful vibe.
From the porch, you can see Itsukushima Shrine and the sea.
It is located on a hill on the way to Itsukushima Shrine from the port.
