The monument on Fuji mound

　"Fuji mound" is located between Minamiyama in Kori and Arakado, and east side of a prefectural road, Oguchi-Iwakura line. It is surrounded by farmland and residential area. This mound is also called as Fuji tomb and said to be a tomb of a powerful family lived in late 5th century. This is assumed to be same generation as Futago (twin) tomb.
It lost its original form, and at present, its length is 30 m and the height is 6.5 m.

　This area is Nobunaga's second son's birthplace and Ikoma mansion was his base. There was a castle, which functioned as fortress to prepare for the attacks. In 1584, two years after Nobunaga's suicide in Honno Temple, the battle of Komaki occurred. Ienaga Ikoma, the 4th generation of Ikoma family, participated in the battle in Ise district, by the order of Nobukatsu, the son of Nobunaga. Ienaga entrusted the task to protect his land to his son Toshitoyo while he was gone. But since Toshitoyo was too young, his relative Ukon took care of it instead. The Shogun, Ieyasu Tokugawa was worried about this area and visited Ikoma mansion with Nobukatsu. They climbed up the mound, and observed his enemy's (Hideyoshi 's) region. From the top of the mound, they could see all around. Therefore, they could plan a strategy for attacking there.

　Later, Toshikatsu, the 6th generation of Ikoma, established a monument on the mound to hand down the family history and achievements to posterity. The monument is hexagonal and an epigraph is carved on the surface, and the basement is turtle-shape stone. It became popular as "the monument on Fuji mound", and later, specified as a cultural property of Konan City in March 1975.
