It is said that this shrine was visited by Minamoto no Yorinoshi in 1062 and by Minamoto no Yoshiyie in 1087 when he came to pray for success in conquering the east lands. Also, after Minamoto no Yoritomo lost the battle of Mt. Ishibashi, he dedicated his manor to the Isejingu Shrine as well as relocating a part of the spirit from Isejingu Shrine and building the Shinmeigu Shrine. Both of these are from articles from the Moukejinja Shrine, and it is unclear whether they are alluding to the Amatsushinmeijinja Shrine or the Moukejinja Shrine.

It is said that the site of the estate of Kudo Yoshitaka - who was appointed the role of guarding the coastline/sea of Tojo in the Kamakura Period - was made into a temple after the Religious Opression of Komatsubara. It is the family temple of Yoshitaka Kudo (Buddhist name: Myoryuinnichigyoku) who was martyred in the Religious Opression of Komatsubara. From the scattering of Kawarake and potteries from medieval times, and the structure of manor's foundation in this area, it can be estimated that the site of Kudo's estate was located lower than where the current temple is.

Kuzugasaki castle is a typical seaport castle in the period of Civil War, which is built on a location where they can overlook the marine traffic of both Amatsukominato and Kamogawa. Built in single-fence style, there are remains of dry moats, earthen bridges, koshiguruwa (defense areas), etc. It is said that in 1572, Masakitaizen Noritoki (lord of Otaki Castle) attacked and destroyed Kuzugasaki Castle, which was then being guarded by Tsunodatangokami Kazumoto (other stories exist). The grave of Tsunoda Kazumoto, who was killed in that battle, still remains at the foot of the castle.

In 1739 when Japan was still closed the country to the rest of the world, a Russian ship led by Spangberg sailed into Funyunohama port for the first time. They anchor their black ship offshore, landed on boats and had two large barrels filled with water.
The locals then greeted the Russians with sake, takuan (pickled white radish) and cigarettes, and were given one Russian silver coin and beads in return.

Near the end of the Edo Period, when the government had an national isolation policy, it constructed cannon bases in many areas to counteract the foreign black ships as well as ordering pine trees to be planted along the seashore to put the coastal villages out of sight from the black ships. These are called Pines of National Defense. They are currently recognized as trees that shield the wind and sand, but those are the real reason why there are so many pine trees near on coast. When World War II broke out and petrol was in short supply, the pines were rooted from the coast, and pine tree oil was refined to be used as a substitute for gasoline. The pine tree forests on the coastline can indeed be called Pines of National Defense in two ways.

This is the family temple of the Tojo clan that was built in 1279 by Tojo Kagenobu as Enmeizan-Nanmyoji temple at Hoshoji Temple. It is said that after Kagenobu died, they built a temple on the burial site and all the chambers built by Kagenobu were merged together. When the Tojo family name died out, the temple welcomed the priest Unreihonryu-Osho and was renamed Soto-sect Eimeiji Temple due to the influence of the Satomi family. It was damaged by the great tsunami of Genroku and was relocated from Azanemoto to the current location.
