Zozan Shrine is a historic Shinto shrine in Matsushiro, Nagano City, dedicated to Sakuma Zozan, a prominent thinker, scholar of military science, and reformer of the late Edo period. A samurai of the Matsushiro Domain, Zozan was known for studying Western learning and introducing new scientific and political ideas to Japan during a period of dramatic change.
The shrine stands on the site of Sakuma Zozan’s former residence, preserving numerous historic structures, monuments, and other traces associated with his life. Several buildings, including the main sanctuary, are registered Tangible Cultural Properties of Japan, while the garden known as Kokoro-no-Ike is registered as a Nationally Registered Monument.
The origins of Zozan Shrine can be traced to 1913, when a memorial ceremony was held marking the 50th anniversary of Sakuma Zozan’s death. Yokota Hideo, a native of Matsushiro who later served as Chief Justice of the Great Court of Cassation, the predecessor of today’s Supreme Court, played a central role in promoting the idea of establishing a shrine dedicated to Zozan.
Permission to establish the shrine was granted in 1931, and Zozan Shrine was officially founded on November 3, 1938. The site of Zozan’s former residence was selected as the location, giving the shrine a particularly strong connection to the man it commemorates.
In much of Japan, Sakuma Zozan’s name is commonly pronounced Sakuma Shozan. In Nagano Prefecture and especially in the Matsushiro area, however, the traditional local pronunciation is Sakuma Zozan. The shrine therefore uses the name Zozan Shrine.

Kogitei was originally an annex of the secondary residence of Mochizuki Mondo, a senior retainer of the Matsushiro Domain. It is also known as a place where Sakuma Zozan spent time under house arrest.
The present building was moved from elsewhere in Matsushiro in 1978 and is designated a Nagano City Tangible Cultural Property.
En’u-tei is a small traditional teahouse where Sakuma Zozan spent the final two months of his life before he was assassinated.
The building was moved to the shrine from Nakagyo Ward in Kyoto. Its name evokes the beauty of scenery veiled in rain and reflects Zozan’s appreciation of atmospheric natural landscapes.
The site of Sakuma Zozan’s former residence is one of the most important places within the shrine grounds. Today, only the well from the original residence remains, together with a stone monument marking the birthplace of Sakuma Zozan.
The site was designated a Nagano Prefectural Historic Site in 1960, allowing visitors to experience the place where one of the most influential intellectuals of the late Matsushiro Domain spent part of his life.
The shrine grounds contain several monuments commemorating Zozan’s writings and ideas.
Monument to Bogaku-fu: This stone monument bears a poem celebrating the beauty of nature and was moved here from Suginami, Tokyo, in 1973.
Monument to Oka-fu: A poetic inscription dedicated to the beauty of cherry blossoms.
Monument to Seikenroku: A stone inscription preserving teachings and writings associated with Sakuma Zozan.
A bronze statue of Sakuma Zozan was erected in 2010 to commemorate the 200th anniversary of his birth. The statue was created by sculptor Isao Tabata.
In 2018, additional bronze statues were unveiled, including figures representing Sanada Yukitsura, lord of the Matsushiro Domain, as well as notable personalities associated with the final years of the Edo period, including Kobayashi Torasaburo, Yoshida Shoin, Katsu Kaishu, Sakamoto Ryoma, and Hashimoto Sanai.
Together, these statues create a striking historical setting and help visitors visualize the network of intellectuals, political figures, and reformers who shaped Japan during the turbulent years leading into the Meiji era.
One of the most peaceful features of Zozan Shrine is its traditional garden and pond known as Kokoro-no-Ike, meaning “Pond of the Heart.” The garden was registered as a Nationally Registered Monument in 2008.
Surrounded by historic buildings and greenery, the garden changes its appearance with the seasons. It provides a tranquil place to pause and appreciate the atmosphere of Matsushiro while reflecting on the history of the late Edo period.
Sakuma Zozan was a samurai of the Matsushiro Domain and a scholar of military science, Neo-Confucianism, and political thought. He lived during the final decades of the Edo period, when Japan was confronted with growing pressure from Western powers and intense debate over how the country should respond to a rapidly changing world.
Zozan studied Western science and military technology and advocated learning from Western countries while strengthening Japan. His ideas placed him among the intellectuals who helped introduce new forms of knowledge during the transition from the Edo period to modern Japan.
His formal name changed during his lifetime, and he was known by the courtesy name Shuri. His posthumous honorific rank of Junior Fourth Rank was conferred in 1889, reflecting the high regard in which his contributions were later held.
The precise origins of the Sakuma family are described differently in historical traditions. One theory traces the family to Sakuma Daigaku, who is said to have served the Sengoku-period warlord Murakami Yoshikiyo. Another tradition connects the family to the lineage of the Kammu Taira clan.
Although the details of the family’s early ancestry differ, these traditions point to Sakuma Zozan’s roots in a long-established samurai lineage.
Zozan Shrine is located in the historic Matsushiro district of Nagano City, an area closely associated with the former Matsushiro Domain and the Sanada family. The shrine can be combined with visits to other important sites in the area, including Matsushiro Castle, Bunbu School, the Former Sanada Residence, and the Sanada Treasures Museum.
It is also within easy reach of other sites that reveal the complex history of modern Japan, including the underground wartime facilities known as the Matsushiro Imperial Headquarters Ruins.
From Nagano Station, take an Alpico Kotsu bus on routes 30 or 48 and get off at Matsushiro Hachijuni Bank-mae. From Shinonoi Station, take a Kawanakajima Bus on route 130 and get off at Konya-machi.
By car, the shrine is approximately 5 minutes from the Nagano Interchange on the Joshin-etsu Expressway. Parking is available, and tour buses can also access the site.
Zozan Shrine offers a quiet way to explore the history of Sakuma Zozan and the dramatic transformation of Japan during the final years of the Edo period. Built on the site of his former home, the shrine brings together historic buildings, gardens, monuments, and statues connected with Zozan and the people of his era.
For travelers interested in Japanese history, Shinto, traditional architecture, and the intellectual changes that preceded the Meiji Restoration, Zozan Shrine provides an especially meaningful stop in Matsushiro. Combined with the area’s castles, former samurai residences, schools, museums, and temples, it offers a fascinating glimpse into the people and ideas that shaped Japan’s transition into the modern age.
