J1planning Acquires “UZ Building” in Kanda-Surugadai, Chiyoda-ku

In April 2025, J1planning Co., Ltd., a Tokyo-based real estate investment firm, acquired the “UZ Building” in Kanda-Surugadai, Chiyoda-ku, from Nao Office Co., Ltd.　

Completed in September 1998, the reinforced concrete property comprises six stories above ground and one basement level, with a total gross floor area of approximately 128.7 tsubo (approx. 4,256 sq. ft.). Each floor offers about 15 to 20 tsubo, catering to demand for compact office spaces.

The building is located just a one-minute walk from Shin-Ochanomizu Station (Tokyo Metro Chiyoda Line) and three minutes from Ogawamachi Station (Toei Shinjuku Line), with JR Ochanomizu Station and Awajicho Station (Tokyo Metro Marunouchi Line) also within walking distance. The area, characterized by a high daytime population, maintains stable demand from small- and medium-sized offices and professional service tenants.

J1planning, headquartered in Tokyo Midtown Hibiya, focuses on a value-add strategy targeting small to mid-sized income-producing buildings in central Tokyo. In Chiyoda-ku, the firm has been actively acquiring older properties (over 20 years old) for renovation and repositioning, reflecting a broader trend of upgrading such assets to enhance their long-term value.
