Nagomi Town in Tamana District, Kumamoto Prefecture, is an idyllic farming area in the middle reaches of the Kikuchi River. It is known for the excavation of a precious National Treasure iron sword from Etafunayama Kofun, its signature historic site, drawing attention as a place of great importance in ancient history. It is a village full of hidden charm where you can enjoy the romance of antiquity and the rural scenery unique to the Kikuchi River basin.

Etafunayama Kofun, Where a National Treasure Iron Sword Was Excavated

The signature historic site of Nagomi Town is Etafunayama Kofun, a keyhole shaped burial mound thought to have been built from the late 5th to early 6th century. The mound is about 62 meters long. An iron sword unearthed in excavations from 1873 onward bears an inscription of 75 characters in silver inlay, and as an extremely important material for understanding ancient Japanese history, the excavated items were designated a National Treasure in 1965. Together with an iron sword from Inariyama Kofun in Saitama Prefecture, this inscription is a valuable clue to the relationship between the Yamato government and the provinces of that era. The area around the mound is developed as a history park, where you can enjoy a walk while reflecting on antiquity.

A History Park That Conveys Ancient Life

Nagomi Town has facilities where you can touch the romance of antiquity. A facility exhibiting excavated items and related materials from Etafunayama Kofun lets you learn about the relationship between ancient Kyushu and the Yamato government.

It is a valuable place of learning where families can experience history.
