In the festival of Oganajinja Shrine, which is the tutelary shrine of the Izumi area, Shishimai and Kakkomai (traditional dances) and Bojutsu (stick-fighting martial arts) are presented to the shrine - these are called the Three Acts of Izumi. It is said that they originate from the Civil War Period, when the area was ruled by the Masaki clan. Oganajinja was called Myokengu before it was renamed in the Meiji Era, and it strongly held the position of the guardian gods of the farmlands and the sea.

In 1899, as part of a national enrichment plan, the farmland management law was put into effect in order to increase agricultural production. The first farmland management project in Kamogawa City area occurred in Tojo, and the Izumi Assembly House was built as a facility where all residents could gather in one place, to mark its completion. It is built in traditional Japanese style of tile thatched pyramid roof structure, but it is distinctive in that it is one room with no pillars.

During the Edo Period, Ohenro pilgrimage in Shikoku and Bando's 33-Kan-non (religious statues) Tour became popular, so similar pilgrimage routes came to be made in other areas who copied the idea. The Awa area, too, created the Awa 88-Holy Grounds Tour and the Awa 34-Kan-non Tour. Also, a 33-Kan-non Tour has come to take place even in just the Nagasago. The first stop in the Nagasago 33-Kan-non Tour is the Tateiwakan-non temple.

Kanayama Castle's ruins, though about 1m of its main castle was carved out before the World War and its hem at the base of the mountain was washed away by a dam lake, still retains most of its shape. It is a rare site by which people can see the difference between the territories of the Masaki clan's dual purpose residence-castles _ that one was made by the Masaki clan as a living castle after the downfall of the Tojo clan and the other was an escape castle which used to belong to the Tojo clan. There is an old location survey map, but as the Koguchi area is outside of the castle's territory, the damage has progressed due to investigations not being carried out in recent years. It is a monument that needs conservation measures by re-doing a basic investigation.
