Nitta-no-shō National Historical Site

Overview

The Nitta-no-shō National Historical Site brings together remains connected to the manor of Nitta-no-shō, once spread across present-day Ōta, Gunma Prefecture, and it holds designation as a National Historic Site. The area is known as the birthplace of the Nitta clan, a powerful medieval warrior lineage, and one distinctive feature — rare among medieval estates in eastern Japan — is that its history can be traced through old documents such as the Chōraku-ji and Masaki papers. In 2000, eleven locations tied to the Nitta clan were jointly designated a national Historic Site.

Highlights

• ●Scattered across the area, these remains trace back to the home base where the Nitta clan, a medieval warrior band, rose to power
• ●A distribution of remains comprising eleven nationally designated locations
• ●The survival of records such as the Chōraku-ji and Masaki papers makes this a rare case among medieval estates in the Kantō region
• ●An estate area spanning the Ōmama alluvial fan and the left-bank floodplain of the Tone River

History

The estate once stretched across nearly the whole of Nitta District in Kōzuke Province, together with parts of Seta and Sai districts and Hanzawa District in Musashi Province, and geographically it centered on the Ōmama alluvial fan and the left-bank floodplain of the Tone River. The area appears to have been known from ancient times: the Engishiki records a "Nitta post station of Kōzuke Province," while the Wamyō Ruijushō lists a "Nitta District Umaya district." In the medieval period the manor took shape as the home base of the Nitta clan, and documents such as the Chōraku-ji and Masaki papers remain valuable sources tracing that history.
