estie Launches June 2026 Edition of Real Estate Market Trends Report 'Estie Market Report'

estie Inc. (Headquarters: Minato-ku, Tokyo; CEO: Ei Hirai; hereinafter “estie”), a company supporting business decisions with Japan’s largest commercial real estate data and industry-specific AI, has launched the June 2026 edition of its latest real estate market trends report, the 'Estie Market Report,' summarizing analysis data from 'estie Office Research.'

This edition continues to investigate the latest supply-demand balance trends for office properties in Tokyo’s five central wards (Chiyoda, Chuo, Minato, Shinjuku, and Shibuya). The submarket focus is on the 'Ichigaya-Kagurazaka' area.

Overview of the June 2026 'Estie Market Report'

In May 2026, the total available floor area in the five central wards was 18,717 tsubo (down 38.5% month-on-month), while the area of leases finalized reached 42,044 tsubo (up 34.8% month-on-month), significantly exceeding new listings. As a result, the total available stock decreased by 7.6% month-on-month to 284,927 tsubo.

By ward, Minato Ward recorded 7,199 tsubo of new listings and 17,675 tsubo of leases finalized (up 36.0% month-on-month). As the largest market in the five central wards, its available stock decreased by 8.6% month-on-month, indicating strong absorption. In Chuo Ward, new listings dropped by 65.0% month-on-month, while leases finalized surged by 72.3% month-on-month, reducing the available stock by 9.2% month-on-month, significantly tightening supply.

In the spotlighted 'Ichigaya-Kagurazaka' submarket, there were almost no new listings in May 2026. However, lease finalizations occurred consecutively, led by KS Building (740 tsubo) and THE PORTAL iidabashi (341 tsubo), causing a sharp reduction in available stock. With limited new supply, the absorption of existing spaces has tightened supply-demand conditions in this area.
