Ancient Memories of Eastern Japan Carved in Japan's Oldest National Treasure Inscription
The Nasu Kokuzō Monument is one of Japan's oldest stone inscriptions, erected in 700 CE. This inscription, carved during the late Asuka period when Japan was transforming into a state governed by the Ritsuryo legal code system, records the transition of a local powerful clan leader to a central government official. It was designated as a National Treasure (Ancient Document) in 1952 as an extremely valuable primary historical source.
Memorial to a Father and Historical Transition Embedded in the Inscription
The inscription contains 152 Chinese characters describing the life of Nasu no Atai Ide, who was appointed from Nasu Kokuzo (regional governor) to Hyotoku (district supervisor), and the memorial sentiments of his son Ishimaro. The content, mourning the virtues of his father who received the official position of Hyotoku from Empress Jito in 689 CE (Eishō 1) and passed away in January 700, reflects the spiritual world of the time where Confucian filial piety merged with Buddhist concepts of reincarnation.
Outstanding Value as One of Japan's Three Ancient Monuments
The Nasu Kokuzō Monument is called one of "Japan's Three Ancient Monuments" alongside the Taga Castle Monument in Miyagi Prefecture and the Tago Monument in Gunma Prefecture. Its uniqueness lies in its character as a private memorial monument, while the other two are official administrative records. The characters carved in Six Dynasties style regular script beautifully emerge when illuminated, conveying the essence of calligraphic art from over 1,300 years ago.
Cultural Heritage Protected by Tokugawa Mitsukuni
This monument, discovered in undergrowth in 1676, was carefully protected by Tokugawa Mitsukuni, the lord of Mito Domain. Mitsukuni built a protective shelter in 1692 and established Kasaishi Shrine. Furthermore, he conducted Japan's first academic excavation at the nearby Samuraizuka burial mounds, establishing the area around the Nasu Kokuzō Monument as "the birthplace of Japanese archaeology."
Encounter with the Mystical Stone Deity
Currently, the Nasu Kokuzō Monument is enshrined as the sacred object of Kasaishi Shrine. Through advance reservation only (Tel: 0287-98-2501), visitors can face Japan's only stone deity while receiving detailed explanations from the shrine priest. This special experience, available for an admission fee of 500 yen, provides a precious opportunity to connect ancient and modern times.
Exploring the Historically Romantic Surroundings
The area around the monument features numerous historical sites including the Nasu Fudoki-no-Oka Yuzukami Museum, the nationally designated historic Samuraizuka burial mounds, and Komaru-san Horinji Temple known for its Saigyo Cherry Tree. Additionally, facilities such as Yuzukami Hot Springs and Tochigi Prefectural Nakagawa Aquatic Park provide enjoyment after historical exploration. The convenient access, about 30 minutes by car from JR Nasushiobara Station, adds to its appeal.
Beauty Through the Four Seasons
Visiting the Nasu Kokuzō Monument with spring cherry blossoms or autumn foliage is exceptional. Particularly from early to mid-April, the nearby Saigyo Cherry Tree is in full bloom, allowing visitors to enjoy the harmony of ancient historical sites and natural beauty. On weekday mornings, you can immerse yourself in ancient romance in peaceful tranquility.
