Taiyuin Mausoleum consists of Haiden oratory, Ainoma middle room and Honden main hall.

You will get into the Haiden oratory at first. The Haiden is connected to the room where width is narrow. That room is called Ainoma. Honden main hall is located next to the Ainoma. The Honden is narrower, but gorgeous room, and enshrines the principal image.

There is no partition between each room, so you can see through the Honden from the Haiden. A big rite is carried out on April 20th. That day is the Memorial Day of Iemitsu's death. Successor of Rinnoji Temple goes into the Honden, and general public can observe the rite from the Haiden.

The area of the Haiden is 64 mats of Tatami, and 140 dragons are painted on the ceiling.

Although, dragon is painted in each small circle, some dragons are different. Why don't you find those differences? Also, there is a wall painting of Chinese lion at the entrance. That was a collaborative work of Tanyu Kano and his young brother Eishin.
