Kanaisawa-hi is a Nationally Designated Special Historic Site located in Takasaki City, Gunma Prefecture. Erected in 726 (the 3rd year of the Jinki era), this natural stone monolith is made of pyroxene andesite, measuring approximately 110 cm in height, 70 cm in width, and 65 cm in thickness. It was established by the Moke clan, an ancient powerful family, to pray for the repose of their ancestors and the prosperity of their lineage based on Buddhist principles. The monument is recognized as one of the 'Three Monuments of KÅzuke' (alongside the Yamagami-hi and Tago-hi monuments) and holds an extremely significant position in Japan's ancient history.
The monument dates back to the early Nara period in 726. It serves as a crucial historical document illustrating how the then-cutting-edge Buddhist philosophy became rooted in local community faith. The inscription records the names of the bloodline members of the Moke clan (the patrons) and the composition of their religious groups. Notably, the characters for 'Gunma' inscribed on this monument are considered the oldest known usage of the name within the prefecture. Furthermore, the inscription provides clues to the political and social structures of the era, reflecting the implementation of the Taiho Code (701) and the administrative system (Kokun-gun-ri system), as well as the influence of government decrees regarding character notation. The Moke clan is believed to be the descendants of the 'Sano Moke,' a local power base for the Yamato Court.

The greatest attraction is the 112-character inscription carved into the surface of the natural stone. The ancient characters are etched into the textured, weathered surface of the pyroxene andesite, showcasing the cultural standards of the time through its unique form and the use of raw natural stone. To ensure its preservation, the monument is housed within a protective structure, allowing visitors to observe how carefully such precious heritage is maintained. It stands as a monumental piece of history alongside the Yamagami-hi and Tago-hi monuments, representing the heritage of the KÅzuke Province (modern-day Gunma).
Kanaisawa-hi is an outdoor historic site accessible regardless of the season. However, the monument is protected by a shelter. The surrounding environment is very quiet, making it ideal to visit during bright daylight hours to fully appreciate the weight of history. You can spend a peaceful moment feeling the breath of ancient times amidst the natural scenery.
While the Kanaisawa-hi is a site for quiet contemplation, the surrounding area offers historical exploration. For example, the roughly 5km route from the Yamagami-hi to the Kanaisawa-hi is a path dotted with monuments related to Manyo-style poetry, allowing you to walk through a historical context. Observing the ancient script and seeing how words were carved in antiquity is a rewarding experience for history enthusiasts.
The area around Kanaisawa-hi is dotted with historical remains. In particular, the Yamagami-hi and Tago-hi monuments, known as the 'Three Monuments of KÅzuke,' are essential to understanding the history of this region. Visiting these sites together provides a deeper understanding of the ancient clans and the spread of religious faith.
