Ishikawa-mon Gate (石川門) 🎥 360°
Lead roof tiles, masugata defense, and Kenrokuen views — a surviving Edo-era masterpiece
Ishikawa-mon is one of Kanazawa Castle's signature gates and among the few castle structures that still survive today. Positioned on the castle's karamete (rear/secondary) side, it faces toward Ishikawa District, which is how it got its name. In the Edo period, it was counted as one of the three principal entrances known as the "San Gomon."
The structure you see today was rebuilt in 1788 (Tenmei 8) after a fire in 1759 (Horeki 9). Ishikawa-mon comprises multiple defensive elements — a turreted gate, adjoining turret, Korai-mon (outer gate), and a taiko-bei (earthen-and-plaster "drum" wall) — arranged in a robust masugata (box-shaped) layout. The roof uses lead tiles, and legend holds that, in wartime, their lead could be melted down to make bullets.
After Maeda Toshiie moved his base to Kanazawa Castle, the fortifications were systematically strengthened and this gate grew in importance. Because the castle served as the Maeda lords' seat of power, the placement of gates and turrets and the overall defensive scheme likely balanced both prestige and military function.
- Masugata Layout & Gate Ensemble: Multiple gate elements — Korai-mon → turreted gate → adjoining turret — convey a layered, heavy-duty defense
- Lead-Tiled Roof: Tiles made with lead are said to have been repurposed for bullets in wartime; the weathered, whitish patina is part of the appeal
- Night Illumination: Seasonal/time-dependent lighting amplifies the atmosphere after dark
- Context in the Landscape: Sited within a panorama that unites Kenrokuen and the castle's stone walls

Sannomaru North Garden (三の丸北園地) 🎥 360°
Open lawn, surviving stonework, and a feel for the castle's original scale
Sannomaru North Garden is an open, plaza-like space on the north side of the Sannomaru area where surviving stone walls and fences blend with greenery to create a calm, contemplative scene. Walking here gives you a feel for the castle's overall scale and the weight of its masonry. It's also a spot where you can sense how the castle's kuruwa (baileys) — Honmaru, Ninomaru, and Sannomaru — were arranged. While no major buildings remain, the stone walls, earthworks, and spatial composition help you imagine the castle's original extent — making this an ideal stop along your walking route.
- Surviving Stonework & Fences: Examine the castle's wall structures running along the garden's edge
- Open Spatial Views: The broad, open grounds reveal the internal organization of the castle; the contrast of greenery and stonework is striking
- Seasonal Nature: Spring greens and cherry blossoms, and autumn foliage, create vivid contrasts with the ruins
