robot home began regularly publishing its Rental Market Report based on executed rental housing contracts, with Q1 2026 published as Vol. 1. The report covers 7,381 contracts that began between January 2025 and March 2026.
The key findings for this issue were that average rents across all locations rose by ¥2,866 per month on a 25-square-meter basis, up 4.4% year on year, exceeding the prior-year level across all building-age categories. The overall rent index was 104.4, calculated with Q1 2025 as 100, while new and relatively new properties led the increase, rising to 111.2. The estimated annual increase in asset value was equivalent to approximately ¥5.3 million per 10-unit building.
The asset value conversion was calculated by capitalizing the increase in monthly rent at an assumed yield of 6.5%. Similar estimates put the increase at approximately ¥14.2 million for new and relatively new properties and approximately ¥4.4 million for properties aged 11–15 years, indicating an uplift effect even for older condominium units.
The report will be published quarterly, with the next issue scheduled for November 2026. The company stated that it will support data-driven real estate management by regularly publishing market data, including the rent index.
