粟嶋神社, Shinto shrine in Japan

Awaishima Shrine is a Shinto shrine in Kainan where visitors come primarily to pray for health and healing. The grounds feature simple structures, a clean courtyard, small lanterns, banners, and wooden prayer plaques where visitors write their wishes and leave offerings.

According to shrine tradition, the deity Sukunahikona no Mikoto drifted ashore at Suzuriu and was enshrined by 21 villagers in the second year of Emperor Keiko. In the Bun'ei era (late 13th century) the shrine was moved from Suzuriu to its present site, and the Ninna-ji temple, proprietor of Hamanaka-no-sho, donated extensive shrine lands. In 1707 a worshipper from Yonouzu in Bungo Province presented three gold-leafed gohei, and in 1797 a believer from Yamada in Kozuke donated the stone bridge.

The shrine is dedicated to Sukunahikona no Mikoto, a deity of healing and medicine also worshipped at Awashima Shrine in Kada, Wakayama. The shrine's festival is held on October 13, and a hina matsuri ceremony takes place on April 3. The Miyamoto family, recorded as priests in the Edo-period Kii Zoku Fudoki, still serves as hereditary chief priests.

The shrine stands on the east-facing middle slope of a hill on the left bank of the Miyagawa, a tributary of the Kamo River, looking toward the inlet of Shimotsu Port in Kainan's Shimotsucho-kata district. The stone drum bridge, moved here in 1990 during widening work on the Miyagawa, now spans the pond in front of the torii; the shrine office and Ryusenji sit below the stone steps. The annual festival is held on 13 October, and a hina festival on 3 April.

The stone bridge in the pond in front of the shrine, called Taiko Bridge, was donated in August 1797 by Jirosuke, a believer from Yamada District in Kozuke Province (present-day Kiryu, Gunma Prefecture). It once spanned the Miyagawa River as part of the approach and was moved here in 1990 when the river was widened. It has been a Kainan City Designated Cultural Property since 1975.
