'Place to commune with noble souls') is a Japanese military and war museum located within Yasukuni Shrine in Chiyoda, Tokyo.

In November 1947 the Fukoku Mutual Life Insurance Company signed a rent agreement with the shrine and began using it as its Kudankita office.

The large exhibit room on the first floor contains a Yokosuka D4Y bomber and Type 97 Chi-Ha recovered from Yap Island, along with a Kaiten-type torpedo and replicas of an Ohka Model 11 aircraft and Mutsu battleship.

Various war-related materials are exhibited in chronological order, including different types of swords, armor, guns, and a golden flag wielded by the Imperial Japanese Army during the Boshin War.

The war flag of the 321st Imperial Japanese Army division displayed in this room is the only one of its kind that has been recovered fully intact.

The museum also houses a cafe where the items on the menu are created using ingredients and recipes resembling those actually used on Japanese Navy ships.
