Saminaga Shrine, Shinto shrine in Japan

Saminaga Shrine is a small Shinto shrine built in the traditional Shinmei-zukuri style in Isobecho-Erihara in Shima. The main hall features a simple wooden structure with straight lines, reached by climbing 36 stone steps from the tall wooden gate at the entrance.

According to the倭姫命世記, the shrine was founded in the 27th year of Emperor Suinin (traditionally 3 BCE). From the Heian period it was subordinate to Izawa-no-miya, and by the Edo period it was called Ōtoshi Shrine. In 1663, 54 shrine officials were exiled after the Kanbun Incident, and in 1871 it received its present name.

The shrine is dedicated to Toshigami, a god connected to seasons and harvests. Visitors can see how local people come during festivals in traditional clothes, bring offerings, and gather to celebrate together.

The shrine is about 16 minutes on foot (830 m) from Shima-Isobe Station on the Kintetsu Shima Line, or 1 minute (100 m) from the Isobe Elementary School bus stop. There is no dedicated parking, but the nearby Tobu-Shisei Regional Union lot (former Isobe town hall site) can be used. The chozuya is normally covered and not in use.

Because the hall faces east, towards Izawa-no-ura, it is one of the few shrines under Ise Jingu's administration whose sanctuary shifts north or south at each Sengū, rather than staying put. The 36 stone steps from the torii are read in the Isobe Kyōdoshi as 36 jun, one for each ten-day period of the year, matching the deity Ōtoshi (the year god).
