It was inside the grounds of the domain's mansion in the Mita district of what is now Minato, Tokyo, and the domain opened it to the public on the fifth day of every month. In 1871, the Arima family moved from Mita to Akasaka, taking the shrine with them, and in the following year they moved the shrine to its present location, on a site that had been occupied by one of the family's mansions. Suitengūmae Station is close to this shrine and takes its name from it. There are about twenty-five other shrines of the same name in Japan.

Yamahibiki stable (山響部屋, Yamahibiki-beya) is a stable of sumo wrestlers, part of the Dewanoumi ichimon or group of stables. It was set up in 1985 as Kitanoumi stable by former yokozuna Kitanoumi, who branched off from Mihogaseki stable. It absorbed Hatachiyama stable in 2006, following the death of its head coach, former ōzeki Hokuten'yū. In May 2010 it also absorbed Kise stable, which was forced to close after its stablemaster, former maegashira Higonoumi, was implicated in the selling of tournament tickets to yakuza members. As a result of this move the stable had 46 wrestlers, making it by some margin the largest stable in sumo at this time. It was the first stable to have over 40 wrestlers since Futagoyama stable in 1998, and had difficulty in finding room for so many. As a result, Kise was allowed to reestablish the stable in April 2012, and all former members of Kise stable, as well as newcomers Jōkōryū and Sasanoyama who had been recruited by Kise-oyakata, joined the reconstituted stable again. Stablemaster Kitanoumi died of colorectal cancer and multiple organ failure on the evening of November 20, 2015. Former maegashira Ganyū, who had been serving as a coach at the stable, inherited it. The stable was renamed Yamahibiki, the elder name used by Ganyū, since the Kitanoumi name could not be inherited, due to it being a one-generation elder stock or ichidai-toshiyori. As of January 2022, Yamahibiki stable had 15 wrestlers. Following the demotion of Kitataiki after July 2017 tournament and Kitaharima after September 2017 tournament, it had no sekitori for the first time since May 2003.

Takadagawa stable (高田川部屋, Takadagawa-beya) is a stable of sumo wrestlers, one of the Nishonoseki ichimon or group of stables. It was formed in 1974 by former ōzeki Maenoyama, and was originally in the Takasago group of stables, but was excommunicated from that group in 1998 due to disagreement over group nominations to the Japan Sumo Association's board of directors. Maenoyama handed over control to former sekiwake Akinoshima in 2009, as he was approaching the mandatory retirement age. A series of wrestlers from Taiwan were recruited in the late 1980s. Later a Mongolian, Maenoyu, was at the stable from 2004 until 2007, but there have been no foreigners recruited since Maenoyu's retirement and the current stablemaster has indicated there are no plans to do in the immediate future.The stable did not have any sekitori between Dairaidō′s last appearance in jūryō in July 2006 and the promotion of Ryūden in September 2012, where he lasted for only one tournament. In September 2014 Kagayaki reached jūryō, ending Takadagawa's sekitori drought. Kagayaki went on to reach the top makuuchi division in January 2016, the first Takadagawa wrestler to do so since Kenkō in 1992, and Ryūden returned to jūryō in November 2016, reaching the top division himself in January 2018. The new Takadagawa head ended the stable's nearly thirteen years of non-alignment with an ichimon in January 2011 when he was accepted into the Nishonoseki group. As of January 2022, it had 22 wrestlers. On 10 April 2020, the Sumo Association announced that an undisclosed wrestler had tested positive for the coronavirus. It was later confirmed to be Shobushi of Takadagawa Stable, a sandanme wrestler who died from coronavirus complications on 13 May 2020. It had also been announced in late April 2020 that seven individuals, including Takadagawa's stablemaster and jūryō wrestler Hakuyozan, were hospitalized after testing positive for the virus. The stable was only one of the 45 stables in sumo not included in the "all-clear" antibody test results issued by the Sumo Association on 6 July 2020. The tate-gyōji at the stable, Shikimori Inosuke, missed the July 2020 tournament with an unspecified illness.
