Kanazawa Castle Park

**Stone wall variations:** The castle's stone walls showcase evolving masonry techniques over 300 years. The Ishikawa-mon Gate area uses nozura-zumi (野面積み, natural boulders fitted without cutting) from early 1600s — irregular, rough, but earthquake-resistant. The Hashizume-mon area displays uchikomi-hagi (打込接ぎ, roughly shaped stones with tighter fitting) from mid-1600s. The Kahoku-mon turret uses kiri-komi-hagi (切込接ぎ, precisely cut rectangular stones fitted seamlessly) from 1700s — the wall surface is nearly flat. Walking the castle perimeter and comparing these three styles is a lesson in castle engineering evolution. English signage explains each section's historical period and technique. **Reconstructed building interiors:** The Gojikken Nagaya (五十間長屋, 50-ken storehouse, 'ken' is a unit = 1.8m, so this is a 90-meter-long building) housed weapons, rice, and provisions. The interior is a vast open space with exposed wooden beams showing traditional joinery — mortise-and-tenon connections without nails or metal fasteners. Exhibits explain reconstruction methods and display architectural models. Climbing to the Hishi Yagura (菱櫓, diamond-shaped turret) upper floor provides views over the castle grounds and Kenrokuen. The interior tour is self-paced; allow 30–40 minutes to read exhibits and appreciate the craftsmanship. **Seasonal events and illuminations:** The castle park hosts seasonal illuminations during cherry blossom season (early April, 18:00–21:00) when 300+ cherry trees are lit and the castle buildings are flood-lit. Autumn illumination (mid-November) highlights maple foliage. The Gyokusen-inmaru Garden (玉泉院丸庭園, reconstructed 2015 on the castle's south side) is a formal daimyo garden with pond, waterfall, and multi-colored stone walls — this area has its own evening illumination (year-round, sunset–21:00, free entry). These illuminations transform the daytime historical experience into romantic nighttime spectacle, worth returning after visiting during daylight.
