Maruyama Shinmei-sha, Shinto shrine in Japan

Maruyama Shinmei-sha is a Shinto shrine in Maruyama-chō, Chikusa-ku, Nagoya, founded in the late 16th century as the tutelary shrine of the former Maruyama village. Its grounds hold a main hall dedicated to Amaterasu Ōmikami and several subsidiary shrines, including Hachiman-sha, Kasuga-sha, Tsushima-sha, Akiba-sha, and Marufuku Inari-sha. Near the entrance stands an Akiba night lamp dated to 1834.

Founded in the late 16th century, during the Genki and Tenshō eras (1570–1593), Maruyama Shinmei-sha served as the tutelary shrine of Maruyama-mura, a settlement that split off from Furui-mura. In 1834, an Akiba tōmyō lantern was erected near the entrance; such lanterns are rare in Chikusa Ward. The shrine held the former rank of sonsha.

This shrine serves as a gathering place where community members celebrate seasonal festivals with food stalls and music, keeping local traditions alive. Visitors can observe people offering prayers, leaving wishes on wooden plaques called ema, and wearing traditional amulets that reflect the deep connection between the shrine and everyday neighborhood life.

The shrine is located in Nagoya's city center and remains free to visit year-round, with early morning or late afternoon being the quietest times for a peaceful experience. Visitors should follow simple courtesies: bow before entering, cleanse hands at the purification fountain, and bow again after praying to show proper respect.

Since around 2005 the shrine has had ties with Grampus S.A, the supporters' group of the J-League club Nagoya Grampus. Besides praying for victory, the head priest brushed the calligraphy for their "Shōkaku" banner, and supporters now visit to pray for wins.
