Joren-ji Ossuary by OOOarchitecture Replaces Aging Concrete with Local Cedar

architecture-design · 2026-04-26

Addressing Japan's declining population and evolving burial practices, Joren-ji Ossuary has replaced an old reinforced-concrete structure with a new timber edifice crafted from locally sourced cedar. This 78 m² project, designed by OOOarchitecture, was finalized in 2024 and introduces a modern approach to sacred architecture that emphasizes continuity over nostalgia. The leading architects involved are Yo Sato, Ryohei Baba, and Hikomaru Wada. Yasutsune-gumi served as the general contractor, while structural engineering was handled by Takashi Baba Structural Design Office. The project was curated by Miwa Negoro, with photography by Yosuke Harigane.
