Three buildings are put in hooked shape. Shimojinko, Nakajinko and Kamijinko from the right of the picture. Model of the construction was imitated from Shosoin House of Nara prefecture. It is called Azekura-zukuri style. The Sanjinko stores 1,200 costumes for the Samurai-style 1,000-person procession. In addition to that, equipments of Yabusame (Archery on horseback) are stored. The Sanjinko will be open 1 week before the festival of Spring and Autumn. Visitors may have a chance to look inside in that week.

There are two big sculptures of elephant on the gable of the Kamijinko. However, ears and tails are different from the real elephant because the chief painter, Tanyu Kano had not ever seen the real elephant when he painted. Therefore, those sculptures were called Imaginary Elephant.
