Japan Office Real Estate Market Size - Share Outlook, Growth Analysis Report and Forecast Trends 2026-2030

Japan's office real estate market is concentrated primarily in Tokyo, which commands one of the largest and most prestigious office markets in the Asia-Pacific region. The Greater Tokyo Area alone accounts for the majority of national office stock, with premium Grade A buildings concentrated in central wards such as Chiyoda, Chuo, and Minato. Osaka serves as the secondary hub with a significant regional market, while smaller but growing office clusters exist in Nagoya, Fukuoka, and Yokohama.
