Japan Offsite Construction Association's Achievements in Noto Earthquake Featured in Forestry Agency's Wood Utilization Case Studies

The Japan Offsite Construction Association (Location: Chiyoda-ku, Tokyo; Representative Director: Toshinari Nagasaka) is pleased to announce that it was featured as one of the primary organizations involved in the supply of wooden temporary housing in the publication 'Utilization of Wood in Emergency Temporary Housing (Case Studies)' created by the Forestry Agency in April 2026 for local governments nationwide.

This document is scheduled to be widely distributed to disaster management officials in municipalities across Japan.

Background and Overview of Publication The Forestry Agency promotes the use of wood and timber in emergency temporary housing to maintain the health and peace of mind of disaster victims and to revitalize local economies. A collection of case studies has been created for disaster prevention officials in prefectures and municipalities nationwide, and our association was introduced as a major organization contributing to the supply of wooden emergency housing.

Our Initiatives Featured in the Collection The collection introduces construction records from Nanao City, Wajima City, and Noto Town in Ishikawa Prefecture during the 2024 Noto Peninsula Earthquake, accompanied by actual construction photos.

The main features of the 'Offsite Construction' promoted by our association include:

1. Rapid Relocatability and Reusability Buildings are constructed in offsite factories and transported to the site by truck. This allows for easy separation from foundations and rapid repeated relocation by transporting units.

2. High Residential and Environmental Performance By adopting timber frame construction (Jiku-gumi) and 2x4 construction (Wakumigami), the housing complies with the energy-saving standards taking effect in April 2025.

3. Promotion of Social Stockpiling We build and operate an information platform for operational support during normal times and disaster response times regarding the social stockpiling of offsite construction.

Comment from Representative Director 'Our association aims to improve residential welfare during disasters and achieve regional revitalization aligned with new work-life styles by researching and developing offsite construction and promoting social stockpiling. We believe being featured in the Forestry Agency's case study collection is proof that our efforts contribute to building a resilient disaster prevention system through public-private collaboration. We will continue to strive for technical development and human resource cultivation to contribute to a safer and more secure society.' — Toshinari Nagasaka, Representative Director, Japan Offsite Construction Association
