Introduction to the Jinmu Hall: The original Jinmu Hall of the puppet Manchurian Japanese army located in the park was completed in July 1936. It was built to commemorate the "2600th anniversary of the accession of Emperor Jinmu of Japan". Jinwuden is neither a shrine nor a temple, but a martial arts hall. It adopts the traditional Japanese style and has facilities such as a main hall, a sumo wrestling ring, a martial arts field, an outdoor archery range, and management rooms.
