The completion ceremony was held by Asano Mitsuakira, who wore the traditional formal attire of the Kuge and donated 300 koku of land to the shrine (Jisha-ryō).

[4][5][6] The most obvious reason for the construction of the Hiroshima Tōshō-gū was that Tokugawa Ieyasu was Mitsuakira's grandfather.

The blast blew off the roof tiles and ceiling, and the building tilted to the north.

The heat from the blast started a fire in the Haiden (Worship hall), and the fire spread to Heiden (Offertory hall), Honden (Sanctuary) and the Shinme-sha (Horse stable).

Those buildings have been around since 1648, were repaired and designated as Hiroshima City Cultural Properties.
