Mt Iizuna 飯縄山
Mt Iizuna straddles Nagano’s northern city of Nagano. 1,917m tall, it is one of Nagano’s Hokushingogaku Northern Five Peaks. Mount Iizuna is a mountain located ten kilometers north-northwest of the heart of Nagano City, Nagano Prefecture. Together with Mount Reisenji, Mount Menō, and others, it forms the Iizuna range. This mountain is a sacred site for mountain-based religious sects such as Shugendo.
About the name of Mt Iizuna 飯縄山. When Iizuna is written as 飯砂, the first character is cooked rice, and the second is sand. It refers to a complex of microorganisms such as fungi and algae found locally in Shinshu, “Tengu-no-mugi meshi” (Tengu boiled rice). In other words, people going into these mountains may have found some edible fungi.

Iizuna Shrine History. This shrine dates to 270 CE, 15th year of Ōjin emperor. It enshrined Tenjin ōdomichi mikoto on the summit of the mountain, and it was originally called īnawa Daimyōjin.
Satomiya 里宮 of Iizuna Jinja. The Satomiya of Iizuna Shrine is 10km south of Okumiya. The village shrine of Iizuna Jinja is reported on by Genbu who says, although the shrine’s kami is Ukemoti, it is really Inari Kami. Genbu further describes Ukemoti as a kami of food in general, and is the Inari kami in the many Inari shrines around the country. The Inari shrines are readily identified by the pair of guardian foxes which protect the rice crop.
奧宮 Okumiya of Iizuna Jinja. The inner shrine of Iizuna Jinja is located at the top of Mt Iizuna. From here you can see Mt. Fuji and Mt. Asanami 浅聞山 in the southeastern part, Togakushi mountain peaks, Otozuma-yama 乙妻 and Nishidake in the northwest, other mountains of Shinshu in the north, mountains in the Hida Japan Alps in the southwest, literally 360 degrees.
Seeking Iizuna Jinja. We were recommended to visit Iizuna Jinja since we would be at Mt Togakushi and Mt Iizuna would be nearby. We were already embarked on our journey when the cryptic message came in: Iizuna shrine may be the origin of the Inari shrine system. We had no time to do preliminary research, so after visiting Togakushi Jinja, we started to look for Iizuna Jinja.
Our navigation system took us to a paved parking lot in the forest on the slopes of Mt Iizuna. Right in front of us stood a torii and beyond it was a narrow trail over exposed tree roots. A foray up the trail led to a second torii but the rest of the way was obscured. This was the trail to the okumiya which we never reached, and we almost got lost on the way back.
We tried two other Iizuna sites but they were in non-descript locations (that offered no clue as to a nearby shrine) and yielded nothing. Later, our friend confessed to being taken to sha at these three locations by a local resident. Unfortunately, we did not have a knowledgable guide. However, we did have an adventure on the mountainside of Mt Iizuna before departing Nagano!
