Because the Meiji government wanted to make a Tokugawa Kamenosuke's territory in Totoumi country, Totoumi's Yokosuka domain head Nishio Tadaatsu was suddenly ordered to move country, so he moved to Kamogawa in March 1869 and called it Hanabusa domain. The Iwatsuki domain regulation district office that was in Yokosuka was assigned as the administrative institution and the domain's school Shudokan was also made. However, due to the abolition of feudal domains in February 1869, Hanabusa domain was abolished and became Hanabusa prefecture. Furthermore, it was unified to make Kisarazu prefecture in November, and it became Chiba prefecture in 1873. Ruins of Hanabusa administrative institution is a historical site representing Kamogawa in the commotion period.

This shrine was established in 1575 by relocating a part of the spirit of Kinokuni-kumano Shrine, and it is told that it was called Nagasa County Ichinomiya-sojagongen. Satomi Yoshihiro donated 30-goku worth of land to be the shrine's territory in the Eiroku Era, but was confiscated along with the Tokugawa government's displacement of the Satomi clan. There is a legend that, when someone met a white snake on their way to worship Grand Shrine Ise and invited it to come along, the white snake was there in Kumanojinja Shrine.

The elevated platform about 10m high, on which Hiejinja Shrine is enshrined, was built by the residents of Maebara as an evacuation area from tsunamis after they learnt a lesson from the damages caused by the great tsunami of Keicho in 1604. The great tsunami of Genroku in 1703 produced immense damages, with 600 homes washed away from the harbor settlement of Maebara, once prospering with fishery and business, and 900 dead _ but it is told that people who fled to the elevated platform of Hiejinja Shrine were survived. The mound was reconstructed after the Genroku tsunami.

In the pilgrimage tours that became popular since the Edo era, the pilgrims wore oizuri, put on knuckle plates and leggings, wore umbrella-hats, held walking sticks and strings of beads or bells, and walked while singing along to pilgrim hymns different for each fudasho stop. Ishimido temple is the 18th fudasho stop of the Awa 34-Kannon visiting pilgrimage tour. "Ishimido mairite oki wo nagamureba, fune ni takara wo tsumuzo ureshiki" (When visiting Ishimido and looking out at the sea, it is nice to see shipping treasures.)

An area called Futago (meaning "twin") in Soro is said to have derived from the fact that, when the warrior Hatakeyama Shigetada was staying in the home of Hatakeyama Shiroemon, he had futago (twin) girls with Shiroemon's daughter. It is said that the kanzashis (ornamental hair pins) of these twins were dedicated to Kazajinja Shrine. Kazajinja used to be located near the coastline, but was relocated to the present area after it was damaged by the great tsunami of Genroku. A part of a medieval Hokyoin pagoda is laid in the shrine premises.

It is said that Minamoto no Yoritomo, who fled from the battle of Ishibashiyama in 1880 September 3rd, had planned to stay the night at the home of Amimoto Hachibei in Kaisuka but had to flee to Niemon-jima Island because Miura Yoshizumi tipped off information of the attack on Nagasa Tsunetomo. It is said that, when Yoritomo left the island, granted the island the name of Hirano and its ownership as well as fishing rights. Ever since, the owner of the island has called themselves Niemon for generations. On the island, there is an elevated sea cave where Yoritomo is said to have took refuge in, and a boulder from where Saint Nichiren prayed to the morning sun.

It is thought that the Acheron worship is the belief that the ghost of a child who built a tower of pebbles for his parents but was unsuccessful every time because a oni (demon) kept coming and destroying it, until one day a Jizo-Bosatsu came and saved the child _ this belief was morphed with Jizo-bosatsu worship of Buddhist and Acheron gods worship of folk beliefs. The Amazura Shore of Acheron (the Saiin Shore of Archen) was a small shrine, but since it grew in the number of Jizos dedicated to it, it was relocated to the elevated sea cave. The Amazura Shore of Archen is a place linking with a re-burial system, which is a ryobo (double graves) system cemetery.

The building of Saitokuji Temple was washed away by the great tsunami of Keicho, but was restored and reopened in 1606 by Choku. It is told that the bronze Buddhist statues of standing Amida-nyorai and standing Ryowakiji, which were stored in Hodoin　Temple - whose chamber was also washed away by the great tsunami of Keicho - were relocated to Saitokuji. This was made during the Nanbokucho Period to Muromachi Period, imitating the main Buddhist statue of Zenkouji Temple in Nagano.

In Kamogawa, there are many tales relating to Minamoto no Yoritomo. The story of when Yoritomo visited Tayuzaki, he saw hoof marks on rocks, so he was convinced there must be a horse around there somewhere and found a horse in a cave which later became his great horse Surusumi - is entertaining as a simple folk tale, along with the legends of Mangizaka and Hatakakematsu (flag-hanging pine). To say that Niemonjima Island is the only place where it tells the true facts relating to Yoritomo is not an overstatement. However, it is fun to visit the Yoritomo legends, separating them from historical facts.

It is said that the mountain of Kuzuryu, which is a semi-independent hill in Emi, is the site of a castle relating to the Satomi clan. This site retains the appearance of the castle well, including the square-shaped lumber end, the divided zones with fences and koshiguruwa (defense area just outside fences) created by moats and earth mounds. Holding the movement on the coastline as well as areas vital to marine traffic is a feature distinctive of castles in Kamogawa, and this Negoya castrum is also thought to be one of such port castles. Near the sea, there are remains of district names such as "Kofunatsuki" and "Ofunatsuki", and documents indicating the fact that coastline settlements in Emi Village were partly put in charge of Satomi's marine army.

There were Tengu (mythical creatures) masks in each of Komogawa's mountain shrines where the Tengu legend is told, but very few remain in the present day. Mt. Mineoka is rich in Tengu legends and there are many tales of Tengu hunting human food, but in Mt. Takatsuru, the legend there is not of Tengu doing bad things but is a tale that humans tried to capture Tengu but were unsuccessful, and as they set fire to the mountain to drive Tengu away, Tengu disappeared and a series of unfortunate incidents followed so a small shrine was built on the top of the mountain to commemorate Tengu.
