The open-Air Antique Fair at Yasukuni Shrine is held once a week from sunrise to sunset with around 10-20 dealers coming from all over Tokyo. However, as Yasukuni Shrine is currently on hiatus, the Antique Fair will resume its activities only in November 2019.
Yasukuni Shrine is a Shinto shrine in Chiyoda, Tokyo. The temple was founded by Emperor Meiji and commemorates anyone who had died in service of the Empire of Japan. Even though the Yasukuni Shrine flea market is not the most impressive of its kind in Tokyo, it is nonetheless entertaining if you are anyway going to visit the Yasukuni Shrine.
Because of its central location, the open-Air Antique Fair at Yasukuni Shrine is one of the most popular of Tokyo Antique and Flea Markets for travelers. The Yasukuni Shrine can be reached within a 5 minutes walk from Kudanshita Sta. on the Tozai, Hanzomon and Toei Shinjuku Subway Lines, or a 10 minutes walk from Iidabashi Sta. (West Exit) on the JR Chuo Line.
Controversies surrounding Yasukuni Shrine: Yasukuni is a shrine to house the actual souls of the dead as kami, or “spirits/souls”. Of the 2,466,532 people contained in the shrine’s Book of Souls, 1,068 were convicted of war crimes by a post-World War II court. Of those, 14 are convicted Class A war criminals.
Since the priesthood at the shrine has complete religious autonomy to decide to whom and how enshrinement may occur, it is thought that enshrinement is permanent and irreversible by the current clergy. And there is little the Japanese government can do about this. According to a memorandum released in 2006 kept by the Imperial Household Agency, Emperor Hirohito refused to visit the shrine from 1978 until his death in 1989, because of the decision to enshrine class A war criminals.
For the above mentioned reasons, keep in mind that visiting the shrine may cause anguish or unrest to some visitors.
