100% Earthquake-Resistant Housing Executive Committee

What 100% Earthquake-Resistant Housing Executive Committee does

The 100% Earthquake-Resistant Housing Executive Committee (一般社団法人耐震住宅100％実行委員会, Ippan Shadan Hojin Taishin Jutaku 100% Jikko Iinkai) is a Tokyo-based Japanese general incorporated association (nonprofit) founded in 2014 as an informal group by N-CN Corporation and formally incorporated on September 1, 2017. Its stated mission is to advance 100% earthquake-resistance in Japan's wooden housing stock, addressing the fact that roughly 81% of Japanese wooden houses do not undergo structural calculation and are therefore vulnerable to collapse in major earthquakes.

The organization operates three integrated product/service pillars. First, TAISHIN100 Standards is a proprietary seismic certification combining allowable-stress structural calculation with seismic grade 3, validated through WallStat collapse simulations using actual Kumamoto earthquake wave data — 8,500 properties are registered as of January 2026. Second, 木質耐震シェルター70K (Wooden Earthquake Shelter 70K) is a room-based laminated-wood shelter built with SE構法 (engineered wood frame) technology, available in 4.5-, 6-, and 8-tatami sizes and priced from 700,000 to 1,000,000 yen (ex-tax) for partial seismic reinforcement without full-house retrofit — 53 installations and 12 community-donated units had been completed by January 2026. Third, the organization is registered with the Ministry of Land, Infrastructure, Transport and Tourism (Registration No. 10, March 2020) to certify existing homes under the 安心R住宅 (Anshin R Housing) system, with 102 homes certified as of January 2026.

The organization generates revenue through corporate membership fees (100,000-200,000 yen annually per member company; 222+ member builders across all major Japanese regions), 木質耐震シェルター70K product sales (sold and installed exclusively through member builders), TAISHIN100 Standards registration and design-document archival fees, and Anshin R Housing certification fees. Go-to-market relies on a hybrid model: a nationwide member-builder distribution channel, direct-to-homeowner sales inquiries, government and municipal partnerships (Yokohama City Hall, Kawasaki City Hall, Ehime Prefecture Ikatacho subsidy program), community-awareness campaigns that donate free shelter units to qualifying community facilities (five phases, 2022-2024), and annual public symposiums at Tokyo University. The organization has no parent company, no external investors, and no disclosed fundraising activity, operating as a member-funded industry association.

Core offering

The organization is a Japanese non-profit industry consortium that promotes 100% earthquake-resistant wooden housing in Japan through three pillars: the proprietary TAISHIN100 Standards certification system (combining allowable stress structural calculation with seismic grade 3, validated by WallStat simulation), the 木質耐震シェルター70K (Wooden Earthquake Shelter 70K) room-unit laminated wooden shelter built on SE構法 technology, and 安心R住宅 (Anshin R Housing) existing-home certification as an MLIT-registered body. Its 222+ member construction companies install and sell the shelter nationwide and adopt the standards.

Product overview

The organization operates three core product/service pillars: (1) 木質、耐震シェルター70K — a room-unit earthquake-resistant shelter product using SE構法 laminated wood frames available in three sizes, sold and installed through member builders nationwide; (2) TAISHIN100 Standards — a proprietary certification system combining allowable stress structural calculations with seismic grade 3, incorporating WALLSTAT simulation validation, with a companion application system for registrations and design document archiving; and (3) 安心R住宅認定制度 — a used-home certification system approved by the Ministry of Land, Infrastructure, Transport and Tourism (Registration No. 10), enabling the '安心R住宅' mark on qualifying existing homes. The three products address different segments of the earthquake-resistant housing lifecycle: existing-home seismic reinforcement (shelter), new-home seismic certification (standards), and used-home market safety (安心R住宅).

Broad incumbents

• セキスイルーフ (Sekisui House Group construction affiliates): Japan's largest homebuilder with proprietary seismic technologies (e.g., beta system, structural calculation-based design). A potential threat as a vertically integrated competitor with vastly greater capital, R&D resources, and brand recognition in the new-home seismic standards space.
• 既存住宅流通促進協議会 (Used Housing Distribution Council): Industry body promoting the circulation and certification of existing homes in Japan. Closely comparable to the committee's Anshin R Housing certification stream at a broader industry-policy level, including MLIT-registered certification bodies.
• パナソニック ホームズ (Panasonic Homes): Major Japanese homebuilder with proprietary seismic-resistance technology (e.g., metal-frame composite structures). Competes for the high-performance-seismic-home customer segment and is a potential partner or competitor in standards advocacy.
• 大和ハウス工業 (Daiwa House Industry): Major Japanese homebuilder with established seismic safety technology and proprietary structural standards. Competes in the same end market (seismic-ready wooden and hybrid homes) and could enter the retrofit/shelter space.
• 日本木造住宅産業協会 (Japan Wood Housing Industry Association): Established nationwide industry association for wooden housing manufacturers. Operates at broader industry level (standards, policy advocacy, R&D) but shares the mission of promoting wooden housing quality and safety. Provides structural comparison as a larger, more established equivalent organization.
• 耐震補強協議会 (Seismic Reinforcement Council): Industry body promoting seismic retrofit for Japanese buildings. Comparable in mission (promoting earthquake-resistant housing) but with broader scope including non-wooden buildings. Represents alternative standardization bodies in the same policy space.

Emerging players

• WALLSTAT (京都大学 生存圏研究所 中川研究室): Wooden house collapse simulation software developed by Kyoto University Research Institute. The committee uses WallStat for TAISHIN100 Standards validation; the underlying technology is a peer IP-layer enabler for advanced seismic verification across the industry.
• ジャパンベストレスキューシステム (Japan Best Rescue System): Diversified home-services and disaster-response company in Japan. Provides empirically related 'home repair' and emergency services comparable to the partial-seismic shelter/retrofit category, though oriented around consumer-facing home emergency response rather than certification.

Direct peers

• JBN (Japan Builders Network) / 全国工務店協会: National federation of small and medium-sized construction companies in Japan. Closely comparable business model: member-based industry organization for residential builders, offering training, technical standards, and certification. Competes for the same member-builder mindshare.
• N-CN Corporation (エヌ・シー・エヌ): Strategic co-development partner providing SE構法 engineered wood frame structural technology for the 木質耐震シェルター70K. Shares headquarters at Akasaka Eight One Building and provides structural materials, technical support, and product components. The committee's product offering is essentially built on N-CN's IP.
