Musashi Mitake Shrine Treasure Hall 武蔵御嶽神社宝物殿

A statue of the samurai Hatakeyama Shigetada (1164–1205) on horseback stands in front of the Treasure Hall. This warlord is believed to have dedicated his armor to the shrine in 1191. The suit of armor, known as the akaito odoshiyoroi or “red thread armor,” is made of small plates of iron and leather bound together with red silk cord. A National Treasure, it was produced in the late Heian period, and is one of the oldest intact sets of Japanese armor in the world.

In 1234, Emperor Shijo (the 87th emperor) presented an ornate war saddle to the shrine. The lacquered wooden saddle is inlaid with circles of mother-of-pearl. It is known as a kagami kura, or mirror saddle. It takes its name from the pommel and cantle, which are clad in gilt copper, polished to a mirror-like finish. This saddle is also a National Treasure.

A mikoshi portable shrine on display was dedicated by the shogun Tokugawa Tsunayoshi (1646–1709). The mikoshi is decorated with the Tokugawa family crest of three hollyhock leaves and is topped with five gilded phoenixes. A reproduction of the mikoshi is used in the annual Hinode sunrise festival (May 8) to mark the opening of Mt. Mitake for climbing and Shugendo training. The festival is one of Musashi Mitake Shrine’s main celebrations, and features a procession of people dressed in samurai costumes.

In addition to the displays of artifacts, a video exhibition features performances of Daidai Kagura, a form of Shinto ritual dance and music. Performances take place at Musashi Mitake Shrine between June and November each year. The shrine priests and their families have been performing Daidai Kagura for 32 generations, since the Edo period (1603–1867). The dance form is an Intangible Folk Cultural Property of Tokyo.

The Treasure Hall is open from 9:30 a.m. to 4 p.m. on Saturdays, Sundays, and public holidays.
