Tsurumaru Storehouse (Tsurumaru Tsuchizo)

The Tsurumaru Storehouse, known in Japanese as the Tsurumaru Tsuchizo, is one of the very few genuinely old buildings to survive inside Kanazawa Castle, a rare Edo-period relic amid a park that is otherwise composed of superb but modern reconstructions. Built in 1848, in the closing decades of Maeda rule, it stands on the eastern side of the castle grounds in the area known as the Tsurumaru, and it has endured where so much else was lost to the fires that repeatedly swept the fortress. In recognition of its authenticity and rarity, it is designated an Important Cultural Property.

The building is a dozo, a traditional fireproof earthen storehouse, its thick walls built up in layers of clay and plaster over a timber frame to protect the valuables within from the flames that were the perennual terror of Japanese castle towns. Inside the Maeda domain, such storehouses guarded armour, weapons, documents and treasures, and their robust, fire-resistant construction is precisely why this one outlasted the grander halls around it. Its two storeys, small barred openings and heavy, sober walls speak to a purely practical architecture, a striking contrast to the ornamental gates and turrets elsewhere in the castle, and a reminder that a great fortress was as much a place of storage and administration as of defence and display.

Today the storehouse is open to visitors and houses displays that explain its history, its construction and the excavations and studies that have illuminated the castle's past. Standing inside its cool, dim interior, running an eye over the aged timbers and thick earthen walls, gives a tangible connection to the daily workings of the Maeda domain that the reconstructed buildings, for all their craft, cannot quite match. It is a quiet, often overlooked corner of the park, and precisely for that reason it rewards the curious visitor who seeks out the real over the rebuilt.

The Tsurumaru area also offers some of the best views within the castle, looking out over the ramparts and terraces toward the city and the hills beyond, and the walk to reach it takes you across the broad, peaceful expanse of the castle grounds, away from the busier gates. In every season the setting is lovely, framed by cherry blossom in spring, maples in autumn and snow in winter, when the white walls of the storehouse merge with the pale sky.

To find it, enter Kanazawa Castle Park, reached by the Kanazawa Loop Bus to the Kenrokuen-shita or Otemon stops, and walk toward the eastern side of the grounds near the Higashinomaru terrace. Entry is free within normal park hours. Allow around twenty-five minutes to look through the storehouse and its displays and to enjoy the surrounding views, and treat it as a rewarding footnote to a fuller exploration of the castle and its magnificent reconstructed turrets nearby.
