Here, there is a group of stone steles surrounding the Yakushi-do (hall dedicated to the healing Buddha), which is said to be the burial ground of the Shinobu Shoji family (the Sato family)

In addition to the tombstones of the brothers Sato Tsugunobu and Tadanobu, there are also tombstones for their father, Sato Motoharu, and their mother, Otowa. An old camellia tree located very close to Otowa's tombstone is"Otowa's Camellia,"and it is said that some of its flowers fall off without opening, symbolizing the grief of a mother who lost her two sons.

The Sato brothers' gravestone is currently protected by a fence, but in the past, people believed that carving the stone and drinking its contents would cure illnesses, in honour of the two brave samurai, and there are traces of carving that remain

The Sato clan is said to have originated with Fujiwara no Chizune, the second son of Fujiwara no Hidesato, who was a descendant of Fujiwara no Kamatari, who played an active role in the Taika Reforms. They ruled the Shinobu region (present-day Fukushima City to Date City) and are therefore known as the Shinobu Sato clan

It is said that Eisaku Sato, the Prime Minister of the Showa era, was also a descendant of Nobuo Sato

The Sato brothers Tsugunobu and Tadanobu, who were active as one of Yoshitsune's four heavenly kings

In 1180, Minamoto no Yoshitsune, the younger brother of Minamoto no Yoritomo, fled to Hiraizumi with a small number of retainers . Fujiwara no Hidehira of the Oshu Fujiwara clan took refuge with him, and Hidehira also had the brothers Sato Tsugunobu and Sato Tadanobu, relatives of the Hiraizumi Fujiwara clan , accompany Yoshitsune as his "assistants."

The Sato brothers assisted Minamoto no Yoshitsune and played a major role in the Genpei War, and are counted among Yoshitsune's "Four Heavenly Kings" in "Genpei Seisui Ki," one of the variant versions of the war chronicle "Heike Monogatari."

The tragic story of Basho's mother and two wives that brought him to tears

The Sato brothers continued to be active, but in 1185,the Battle of Yashimathe elder brother Tsugunobu was killed by an arrow while shielding Yoshitsune. In 1186, the younger brother Tadanobu was attacked while hiding in Kyoto and, despite his valiant efforts, was no match for the enemy's numbers and committed suicide.

Tsugunobu's end

The above is a description from "The Tale of the Heike," while "Azuma Kagami" states that he had already died in the Battle of Ichinotani, which took place on March 20, 1184

The Sato brothers were never able to see the land of Shinobu again. And their mother,Lady Otowa,grieved deeply upon learning of the deaths of her two sons.

It is said that when Tsugunobu's wife, Wakazakura, and Tadanobu's wife, Kaede, saw this , they suppressed their own grief, donned their husbands' armor, dressed as warriors, and appeared before Otowa, saying, "Tsugunobu and Tadanobu have returned in triumph," to cheer her up.

When Matsuo Basho heard this story, he was moved to tears, saying, "How can such a brave name have become known to the world?" Dolls of Wakasakura and Kaede dressed as warriors from this time are enshrined in the main hall of Ioji Temple
