High-Grade Midsize Office Building Completed in Jimbocho by Nippon Steel Kowa Real Estate

BIZCORE Jimbocho II, a high-grade midsize office building that Nippon Steel Kowa Real Estate had been developing in Kanda-Nishikicho 3-chome, Chiyoda Ward, Tokyo, was completed May 29, 2026. The property is the 11th project in the company’s BIZCORE series.

The property has nine floors above ground, with a typical floor plate of approximately 89 tsubo (approx. 3,200 sq. ft.). The first-floor common area includes refresh booths and private booths, and some floors will include setup office space. The property is located a four-minute walk from Jimbocho Station on the Tokyo Metro Hanzomon Line and Shin-Ochanomizu Station on the Tokyo Metro Chiyoda Line. It offers access to six stations and seven train lines, and BIZCORE Jimbocho, which the company completed in 2017, is located across the street.

The vacancy rate for midsize office buildings within a five-minute walk of Jimbocho Station with typical floor plates of 50 to 200 tsubo (approx. 1,800 to 7,100 sq. ft.) has continued to decline from 7.23% at the end of May 2023 and currently stands at 2.35%, indicating tight supply-demand conditions, according to editorial research based on estie Office Research. The company has continued to supply the series in central Tokyo, including the completion of BIZCORE Iidabashi in July 2025 and BIZCORE Nihonbashi in December 2025, and aims with this property to capture demand for high-specification midsize office space in the Jimbocho area, where supply and demand are tight. （see related article:Nippon Steel Kowa Real Estate Completes BIZCORE Iidabashi Office Project, Nippon Steel Kowa Real Estate Completes “BIZCORE Nihonbashi,” the 10th Building in Its High-Grade Mid-Size Office Series）
