Japan's vacant house crisis prompts new third‑party referral service

Japan faces a record‑high vacant‑house problem, with about 9.02 million empty homes—13.8 % of the housing stock—according to the latest Ministry of Internal Affairs and Communications survey. Many of these properties become vacant after inheritance, as heirs struggle to decide whether to sell, rent, demolish or keep them, while the Ministry of Finance sees inheritance‑tax revenues surge to ¥3.8 trillion in fiscal 2026.

To address the difficulty families have in raising the issue, idea株式会社 launched a “third‑party referral” system. Friends or relatives can, with the owner’s consent, introduce the heir to the company, which then handles valuation, disclosure and transaction without requiring the introducer to act as a sales agent. The service operates in Tokyo, Kanagawa, Chiba and Saitama, charging a flat referral fee ranging from ¥30,000 to ¥100,000 depending on the sale price. The initiative aims to lower barriers for heirs who lack real‑estate expertise and to reduce the growing number of abandoned properties.

Commentators also note alternative approaches such as lease‑back arrangements, where seniors sell their homes but continue living in them under a long‑term rental contract, potentially easing both housing and tax pressures.
