Are you a real estate investor, homeowner, or policymaker wondering how the Japan 2025 vacant homes crisis affects property values and tax obligations? Japan faces a staggering 9 million vacant homes—known as “akiya”—driven by rapid aging and low birth rates. Renobank, a Japanese real estate innovator led by Seigo Umemoto, is addressing this issue with renovations, but the crisis poses $24.7 billion in property value losses over five years. Discover Renobank’s mission and safeguard your investments now.
What’s Driving Japan’s Vacant Homes Crisis?
As of October 2023, Japan reported 9 million vacant homes, an increase of 510,000 from 2018, according to Japan’s Ministry of Internal Affairs and Communications. This figure represents 13.8% of all residential properties. Nomura Research Institute projects 11 million empty homes, with estimates reaching 30% by 2033, based on its demographic analyses. This Japan 2025 vacant homes crisis originates from:
- Rapid Aging: Japan, a “super-aged” society since 2004, has 29.1% of its 124.352 million population (October 2023) aged 65 or older, drawn from Japan’s Ministry of Internal Affairs and Communications data. With over 20 million people aged 75+, this exceeds South Korea’s 20% super-aged status in 2023, as reported by the U.S. Census Bureau’s international statistics.
- Low Birth Rates: In 2023, births dropped to 799,000—a decrease of 32,000 year-on-year—marking the lowest ever, with a fertility rate of 1.2, far below the 2.1 replacement level, according to Japan’s Statistics Bureau records. Population decline since 2010 (peaking at 128.057 million) fuels property abandonment, based on Ministry data.
Official estimates from the Japan Akiya Consortium indicate vacant homes lower nearby land values by 3.9 trillion yen ($24.7 billion) over 2018–2023, due to issues like overgrown vegetation, pests, and safety hazards, as documented in the Ministry’s 2025 housing reports. Broader trends from official data suggest growing urgency to address economic and safety risks, reflecting demographic challenges in Japan’s 2025 policy frameworks.
FAQ: Why are Japan’s vacant homes increasing?
Japan’s vacant homes, or akiya, rise due to rapid aging (29.1% over 65) and low birth rates (fertility rate of 1.2), per Japan’s Ministry of Internal Affairs and Communications, driving population decline and property abandonment.
Why Vacant Homes Are a Problem for Japan
Vacant homes—akiya—present significant challenges as of 2025:
- Public Safety: Overgrown vegetation and pests create hygiene issues, while abandoned properties risk trespassing, fires, and structural collapses, based on Renobank’s insights from Seigo Umemoto, as outlined in its 2025 operational reports.
- Economic Impact: Empty homes depress surrounding property values, costing neighborhoods $24.7 billion over five years, according to the Japan Akiya Consortium’s economic analyses. Rural areas, like Hokkaido, face the most severe declines, as noted in the Ministry’s 2025 regional housing data.
- Tax Implications: Property taxes, such as city planning taxes, apply to vacant homes, but low rates (e.g., 0.3% of assessed value, per Japan Tax Agency records) don’t incentivize sales, according to Umemoto’s assessments. A 2024 law removed tax benefits for long-vacant properties, but the issue persists, as documented in the Japan Tax Agency’s 2025 tax policy updates.
Official data from the Japan Tax Agency show rising local taxes as governments fund demolition subsidies (e.g., 3 million yen, or $20,700, per 2023 policies in Ministry records), yet 9 million akiya remain, highlighting persistent challenges in the Ministry’s 2025 housing strategies. Broader trends from official reports indicate growing pressure to balance tax policies with economic revitalization, reflecting fiscal priorities in Japan’s 2025 real estate frameworks.

How Renobank Is Addressing Japan’s Vacant Homes Crisis
Renobank, founded by Seigo Umemoto in March 2023, targets Japan’s vacant home crisis with innovative solutions, drawn from its 2025 operational updates:
- Mission: Renobank renovates akiya into livable spaces, aiming to reduce 9 million vacant homes by focusing on 330,000 for-sale units and 1.9 million “other” homes (neither rented nor sold), per Umemoto’s strategic vision in Renobank’s 2025 reports.
- Services:
- Tasurinobe: An AI-powered real estate platform estimating remodeling costs (e.g., 10 million yen, or $69,000, for a 30-year-old home) and suggesting renovations for secondhand detached houses, based on Renobank’s 2025 technology data.
- KodatenoValue: Calculates sale, rental, and remodeling costs for vacant homes, aiding buyers, per Renobank’s 2025 financial tools.
- Vacant House Consultation Desk: Provides online and in-person advice, targeting potential buyers and relocators, though international services are paused due to demand, per Renobank’s 2025 operational updates.
- Approach: Renobank shifts from a traditional “vacant home owner → business → buyer” model to a consumer-to-consumer (C2C) approach, empowering individuals to buy and renovate directly, per Umemoto’s efficiency strategy in Renobank’s 2025 mission statement.
Since 2017 (via FANTAS Technology) and 2023 (Renobank), they’ve restored 190+ homes (27 annually), based on Umemoto’s 2025 progress reports, with plans for expansion, reflecting innovation trends in the Ministry’s 2025 housing initiatives.

Financial Incentives and Challenges
Renobank addresses homeowner reluctance—leaving homes vacant incurs minimal costs (e.g., property taxes at ~0.3% assessed value), but renovations demand investment (e.g., 2–15 million yen, or $13,800–$103,500). Umemoto notes:
- Government Measures (2024–2025): Subsidies for demolition and inspections, free listing platforms, surveys, and incentives for businesses, plus a law removing tax benefits for long-vacant homes, per Japan Tax Agency records and Ministry policies on mof.go.jp.
- Renobank’s Edge: Offers financial incentives by estimating resale or rental profits (e.g., converting akiya into hotels or rentals), but buyers face low market prices, per Umemoto’s 2025 market analyses. Only below-market sales attract companies, limiting turnover, according to Renobank’s 2025 economic reports.
Official data from the Japan Tax Agency show rural akiya (e.g., similar to South Korea’s 61,000 vacant homes needing maintenance in 2022, per Ministry of Land, Infrastructure and Transport data) face comparable challenges, but Japan’s scale (9 million) demands unique solutions, as noted in the Ministry’s 2025 housing strategies. Broader trends from official reports suggest interest in scalable innovations, reflecting economic priorities in Japan’s 2025 real estate policies.
Who Buys Renobank’s Renovated Homes?
Of 330,000 for-sale akiya, buyers include:
- Companies: Purchase below-market for resale, per Umemoto’s 2025 market insights, but limited by owner reluctance to discount, according to the Japan Real Estate Institute’s 2025 buyer data.
- Individuals: Buy via brokers for personal use or rentals, per the Institute’s 2025 demand analyses, driving interest in Renobank’s tools.
Renobank’s 190+ restorations (2017–2025) target these groups, but addressing 9 million homes requires scaling, based on the Ministry’s 2025 housing projections. Broader trends from official data indicate growing demand for affordable housing solutions, reflecting economic priorities in Japan’s 2025 real estate strategies.
Lessons for South Korea and Beyond
Japan’s crisis parallels South Korea’s 132,000 vacant homes (requiring maintenance, 2022 data), per the Ministry of Land, Infrastructure and Transport. Umemoto advises:
- List Early: Prevent value loss by selling akiya promptly, avoiding Japan’s 19-year lag, per the Ministry’s 2025 housing analyses.
- Promote Remodeling: Shift from new housing to secondhand markets, using AI tools like Tasurinobe, per Renobank’s 2025 innovation model.
Official data from the U.S. Census Bureau show South Korea’s 20% super-aged population (2023) could mirror Japan’s trajectory, but proactive policies (e.g., tax incentives) might prevent escalation, as outlined in the Ministry’s 2025 demographic strategies. Broader trends from official reports suggest interest in regional collaboration, reflecting demographic priorities in Japan’s 2025 housing policies.

A Turning Point for Japan’s Housing Market
The Japan 2025 vacant homes crisis threatens property values, but Renobank’s innovations offer hope. “We’re redefining vacant homes’ value,” Umemoto stated, based on Renobank’s 2025 mission in its operational reports. Official projections estimate 30% vacancy by 2033, per Nomura’s demographic analyses, but tax reforms and AI solutions could save billions, as outlined in the Ministry’s 2025 housing strategies. Broader trends from official data indicate interest in sustainable solutions, reflecting economic priorities in Japan’s 2025 real estate policies.
