Aso Shrine

**Reconstruction observation:** A small museum (rebuilt 2022) documents the gate's collapse and reconstruction with photos, architectural drawings, and a 1:10 scale model showing the joinery system. The explanation of why the original gate collapsed (ground liquefaction shifted the foundation) and how the new gate prevents recurrence (deeper foundation, flexible joint systems) is accessible even for non-engineers. **Ceremonial calendar:** Aso Shrine hosts the Onda Matsuri (July) — a rice-planting ritual involving shrine maidens carrying seedlings in a procession while singing traditional songs. The matsuri was suspended 2016–2022 during reconstruction and resumed in 2023. The continuity of ritual across reconstruction is Shinto's defining characteristic. **Architecture viewing:** The rebuilt gate is unpainted cypress — currently pale gold, it will gray naturally over decades. Viewing the gate now (fresh wood) vs. 50 years from now (weathered gray) represents seeing two different aesthetic states of the same structure. The Japanese concept of wabi-sabi applied to architecture.
