'BORDER5', the Certification Site for Top 5% Well-Managed Condominiums, Unveils Renewal

Sakura Jimusho Co., Ltd. (Shibuya-ku, Tokyo / President: Naoya Yamamoto), a "real estate expert" providing comprehensive real estate consulting for individuals, home inspections, and consulting for condominium management unions, has renewed its condominium management evaluation site "BORDER5." The renewal strengthens its function as a platform connecting management unions with prospective buyers. Additionally, as of April 2026, the site's Editor-in-Chief position was handed over from current Chairman Rinka Onishi to President and CEO Naoya Yamamoto. Please feel free to contact us for inquiries or interview requests regarding this matter. Evaluating "Community" and "Disaster Preparedness" Overlooked by Existing Systems BORDER5 was launched in 2019. The national "Management Plan Certification System" (17 items) and the industry association's "Appropriate Condominium Management Evaluation System" (30 items) both focus primarily on operational aspects and building facilities, with almost no evaluation items for community vitality and disaster preparedness. BORDER5 fills this gap with its unique 40 items across 4 axes. Four Management Capabilities Evaluated by BORDER5 - Union Operation Capability: Metrics regarding smooth management union operations - Maintenance & Financial Capability: Metrics regarding financial soundness and repair standards - Community & Livability Capability: Metrics regarding the cultivation of independent communities and livability - Disaster Preparedness Capability: Metrics regarding the cultivation of independent disaster prevention organizations and evacuation/mutual aid standards Listing is possible by scoring 16 or more points in basic items and 12 or more points in bonus items (top 5%). Screening is free and requires annual renewal. Driving the "Visualization" of Management Forward Through the Renewal - Expansion of Listed Condominiums: In addition to certified condos, some condos with a track record of using our consulting services are newly listed. - Unification of Evaluation Standards: The distinction between large-scale and small/medium-scale condos has been abolished, unifying the standards. - Strengthening of Information Dissemination Functions: Added features allowing management unions to publicize their unique initiatives by posting documents and external links.
