In the Iino district of Futtsu City, within the alluvial plain in the lower reaches of the Koito River, there is a group of burial mounds built from the middle to the end of the Kofun period, between the 5th and 7th centuries.
A total of 49 tumuli have been identified, including 11 anteroposterior circular mounds, 7 square mounds, 19 circular mounds, and 12 mounds of unknown shape, of which 23 are currently known.

The Uchiurizuka tumulus cluster is a valuable site for understanding the way of the chiefs of the Kanto region at that time, and the Uchiurizuka tumulus cluster was designated as a national historic site on September 20, 2002.
On June 20, 2025, the Subcommittee on Cultural Properties of the Council for Cultural Affairs of the Government of Japan newly recommended seven tumuli （ Uenozuka tumulus, Kujozuka tumulus, Sanjozuka tumulus, Kamezuka tumulus, Furuzuka tumulus, Warimizuka tumulus, and Inariyama tumulus ） to the Agency for Cultural Affairs to be designated as National Historic Sites. On September 18, 2025, they were officially recognized as National Historic Relics.
However, the reality is that not many people, including local Futtsu citizens, know much about the location of the Uchinarizuka tumulus group.

Therefore, we asked a guide from the Lifelong Learning Division of Futtsu City to guide us around the tumulus group, and we hope that this tour will help to increase knowledge and interest in the Uchiurizuka tumulus group, which is also a national historic site.
We will also provide Futtsu City's specialty "Teppo-maki" for lunch, which has been certified as a 100-year food by the Agency for Cultural Affairs, to give visitors a cultural experience of food.
