Masaki Yoritada, who lost his Katsuura Castle in the 1590 Seizure of Kazusa by Toyotomi Hideyoshi, moved his manor to Narukawa and served the Satomi family. The Masaki clan's distinctive style of castle foundation is adhered to it, and has made an open and flat accommodation section at the top of a hill by applying stepped-cuts around the elongated hillside and separating it from its surroundings. As to what sort of building stood here, it has not yet been investigated. Kansai's daughter was Tokugawa Ieyasu's concubine "Oman-no-kata" and became the biological mother to sons Yorinobu (Tokugawa family in Kishu) and Yorifusa (Tokugawa family in Mito).

Hokoji temple originates from the Keinichi-Sanhonjuin Myoyoji Temple established by Nichiren in 1264. It used to be a attached betto temple belonging to Kamojinja Shrine, but it is told that it was rebuilt with the aid of Shogenin temple of Masaki Kansai's wife in 1599 as it was starting to decline during the Azuchi-Momoyama Period. Hokyoin pagodas from the Muromachi Period and early Edo Period stand in the cemetery. As basic investigations that are thorough enough are not taking place, the history of these stone artifacts are unknown.

Yamaguchi Shido studied Japanese classics as a pupil of Kada Niroyuki and has written works such as "Mizuho-den", which is his own distinctive interpretation of ancient literature, and "Hyakushu-seikai", in which he again adds his distinctive interpretation to "Ogura-hyakushu" (selected works by Fujihara Sadaie). He taught Japanese classics to nobles who served the Imperial court in Kyoto, and also worked as a lecturer to Emperor Ninko. A memorial monument of Yamaguchi Shido stands in the premises of Kippohachimanjinja Shrine.

It is said that this is one of the 66 Ankokujis built all over the country by Ashikaga Takauji to pray for the soul of Emperor Godaigo. It destroyed because of war fire etc., and was rebuilt in 1546. A substitute primary school building was built on the temple grounds in the early Meiji Era, and Koizumi Chikashi was one of those who enrolled.

It is told that in 1178, when Taira Shigemori asked Buddha statue-maker to sculpt a Koyasu-Jizo to pray for his sister Tokuko's safe delivery, a healthy prince (later Emperor Antoku) was born so he built this Ryukoji Temple _ then ruled by the Nagasa clan _ and stored that statue inside. The statue of Jizo-Bosatsu, likely to be a work from the early Muromachi Period, is attracting worshippers as a god of safe delivery. Also, a Hokyoin pagoda, which prays for the souls of victims of the Tenmei famine, can be seen in the temple premises.

The Kakko-mai dance is presented to two shrines annually on July 24th, alternating between the premises of Kasugajinja Shrine and Atagojinja Shrine in mount Sho-u. This Kakko-mai dance is said to have originated from rain-making rituals done by Satomi Yoshizane in Takakurajinja Shrine during Tenmon Era drought. It is acted by three lions with kakkos (type of drum) attached on their stomachs, after a forerunner by Sekimen, Okame, and Douji.

Ohyamasenmaida is the collective name for a cluster of terraced paddy fields on the hillsides in the altitudes of 90m-150m, in an area spanning 600m to both East and West. There are actually just 375 paddy fields, but the name "senmaida" _ meaning "1000 paddy fields" _ is used to express that there are a lot of fields. The period of time when these terraced fields, the forests around it and the scenery of the settlements were made is unknown, but it can be estimated from the rice output etc. which is already known, that they were largely completed in the Civil War Period.

Tales have been told that both Ohyamaji temple and Takakurajinja shrine was opened by the monk Ryoben. It was destroyed in the Satomi clan's Tensei civil war, and was rebuilt in 1586. A dragon made by Ihachi watches over the Nagasago. The temple is a treasure house of rare historical sources such as groups of Kyozuka (mound of Buddhist scriptures) and Ichiji-isseki-kyo (scripture stones written with a scripture word for each of the stones).

In the 1880s, the activities that remain in the history of Kamogawa's Democratic Rights Movement became livelier, and Suehiro Tetcho and Taguchi Ukichi in 1880, and Ono Azusa in 1882, were welcomed to the campaign by Agata Fusayoshi and Yasuda Kaoru respectively. On the graves of Yasuda Kaoru, who performed as a prefectural assembly member from the Rikken-Kaishin Party (Constitutional Progressive Party)as well as a House of Representatives member, and Yasuda Masao, who was a House of Representatives member from the Minsei Party (Good Governance Party), the inscription and emblem of "Awa-no-Kami Katsu Kaishu" is etched in.

As much of Kamogawa is formed by soft mudstone which is easily excavated, there are many caves made. The cluster of cave-style tombs at Ohyama, other than changing the entrance part into an arch-shape for later purposes such as air-raid shelters, still maintains the structure of the caves well. There used to be six caves open along the mountain ridge, but now the lowest cave is open. To whom these tombs belongs is unknown. There is also a legend that it is a cave in which Minamoto Yoritomo took refuge. It is historically registered as a side hole tomb, but it is meant to be a cave-style scaffold tombs.
