Zozan Shrine

A Shrine Built for a Bakumatsu Thinker

Zozan Shrine (象山神社, Zōzan Jinja) is a Shinto shrine in Matsushiro-machi, Nagano City, Nagano Prefecture, founded on November 3, 1938 to enshrine the late Edo-period scholar Sakuma Shozan; its six shrine buildings were listed together as Registered Tangible Cultural Properties on December 26, 2005.

Sakuma Shozan (1811 to 1864) was born into a samurai family of the Matsushiro domain. He moved from Confucian studies to Dutch learning and Western gunnery, and the students who passed through his Edo academy included Katsu Kaishu, Yoshida Shoin and Sakamoto Ryoma. When Shoin tried to stow away on an American ship in 1854, Shozan was implicated and confined to Matsushiro for nine years. Released at last, he went to Kyoto and was cut down by assassins there in 1864.

A note on the name. The character pair 象山 is often read Shōzan, and you will see the scholar's name written that way in many English sources. The shrine itself, and the reading recorded in the Agency for Cultural Affairs database, use Zōzan.

The idea of a shrine took shape at the 50th memorial of Shozan's death in 1913. Yokota Hideo, a Matsushiro native who had served as chief justice of the Great Court of Cassation, championed the project. Support came from every municipality in Nagano Prefecture, the Shinano Education Association, schools and educators across Japan, and permission to found Zozan Shrine was granted in 1931. The deity was installed 74 years after Shozan's death.

Next door is the site of Shozan's birthplace. The Sakuma house was abolished after his murder and the residence disappeared soon afterwards; the shrine notes that only a well remains.

How the Zozan Shrine Grounds Fit Together

All six registered buildings date from 1938, the founding year, and their registration numbers run consecutively from 20-0221 to 20-0226. Each was registered separately, but they are best understood as parts of one building campaign.

The approach ends at the south-facing worship hall and prayer hall, with the main hall behind it. In the middle of the grounds, toward the west, the treasure hall and the ema hall both face east. On the south side stands the west-facing shrine office, and the saikan sits to its northeast.

The registrations fall into two groups by criterion. The main hall, the worship hall and prayer hall, the saikan and the shrine office were judged to be models of form. The treasure hall and the ema hall were registered for their contribution to the historic landscape, which is to say for the part they play in the ensemble.

Sizes vary a good deal, from the 30 square meter treasure hall to the 229 square meter shrine office. The saikan has a Sangawara-buki tile roof and the other five are listed as Dōban-buki copper. One record disagrees with itself: the ema hall's structure field in the national database says steel sheet, while the description on the same page says copper.

Two older buildings arrived later. The Kogitei is an annex from the lower residence of the Matsushiro retainer Mochizuki Mondo, where Shozan lived during his confinement; visiting activists are said to have debated the state of the country in its upstairs room. It was moved to Zozan Shrine in 1978. The En'utei is a tea room said to come from the Kyoto house on Kiyamachi where Shozan spent his last two months. After restoration work, a tea gathering was held there on October 12, 2025.

At the entrance to the birthplace site lies the Kokoro no Ike pond, fed by the sensuiro, a network of channels that carried water through Matsushiro's samurai gardens. The flow reaches the pond after passing through gardens upstream and continues on to another residence garden below.

Festivals at Zozan Shrine

Zozan Shrine holds its main festivals twice a year. For the 2026 fiscal year the spring festival is scheduled for April 11 and the autumn festival for October 11. A memorial rite takes place on July 11 and a birthday rite on February 11.

Because Shozan is honored as a patron of learning, many visitors come to pray for exam success. Prayer ceremonies are held daily, but the shrine asks people to phone ahead so a time can be arranged.

Visiting Zozan Shrine

Entry to the grounds of Zozan Shrine is free. Amulets, goshuin stamps and prayer bookings are handled between 9:30 a.m. and 4:00 p.m.; the phone number is 026-278-2461. The shrine's website does not give gate hours, so if you plan an early morning or evening visit it is worth calling first.

By public transport, start at JR Nagano Station. From stop 3 at the Zenkoji exit, take an Alpico bus bound for Matsushiro High School, ride about 30 minutes to Matsushiro Hachijuni Ginko-mae, and walk about 10 minutes. The Sanada Treasure Museum is also about 10 minutes away on foot. Drivers should allow about 2 to 2.5 kilometers from the Nagano interchange on the Joshin-etsu Expressway; there is parking.

All six registered buildings are seen from outside, and no public opening of the interiors is advertised. The shrine's website says nothing either way about photography, but please hold off during festivals and prayer ceremonies. What to look for at each building, and where to stand, is covered on the individual pages.
