The first part of the shrine building (the "Honden" or ""Okuden"" housing the deities of aikido) was completed in late autumn, 1943. The second bigger part (the Haiden) was erected in front of the Honden in 1962. Both parts were renovated by care-taker Morihiro Saito in 2001-2002 with the approval of Dōshu Moriteru Ueshiba. This renovation also included a fence set up around the compound, and a stone with the carvings "Aiki Jinja" designed by Seiseki Abe, a master of both calligraphy and Aikido, who was also the calligraphy teacher of Morihei Ueshiba. A large statue of the founder of aikido was erected in the shrine grounds and unveiled on 8 November 2009. Surplus material from this monument was used to make a bust of the founder which was unveiled at the newly rebuilt Iwama Station on 24 July 2012.
