泉神社, Shinto shrine in Japan

Izumi-jinja (泉神社) is a Shinto shrine in Maibara, Japan, made up of simple wooden buildings set among old trees. A stone gate marks the entrance, and a path lined with stone lanterns leads to the main sanctuary and offering altars.

According to the shrine's tradition, Emperor Tenji designated this site as a training ground for archery and horsemanship; when people settled here, a sacred spring welled up and was named Tensensho, later changed to Oshimizu. The shrine is dedicated to Susanoo and Ōnamuchi. The spring was selected as one of the Heisei-era Top 100 Famous Waters in 1985.

The shrine is dedicated to water and a sacred spring that local people have long revered. Visitors can watch others place offerings at the altars and observe simple prayer rituals at the main sanctuary.

The shrine is easiest to reach on foot along a marked forest path lined with stone lanterns. Sturdy footwear is a good idea, as the ground can be wet or slippery depending on the season.

The spring is called Oshimizu, not Mizumuki. According to shrine tradition, Emperor Tenji designated this ground for archery and horsemanship practice; when people settled here, a sacred spring welled up and was named Tensensho, later renamed Oshimizu. It is one of the three famous waters of Mount Ibuki, and its source is off-limits, so visitors collect water at a downstream draw point.
