Mori Building

Mori Building

Mori Building is a privately held Tokyo developer that pioneered Japan’s integrated megaproject model. Its 2003 Roppongi Hills complex placed offices, residences, retail, a museum, and a broadcast facility onto a single superblock, furnishing Goldman Sachs with its flagship Tokyo base. That template now repeats across the Azabudai Hills and Toranomon Hills districts, each layering cultural venues, international hotels, and transit hubs into mixed-use towers. The firm deploys its own balance sheet into long-duration urban consolidation. Its portfolio spans office, residential, retail, hospitality, and cultural real estate, with stage coverage from land assembly through stabilized operations. Recent commitments include a ground-up redevelopment at 346 Madison Avenue in New York with co-investor SL Green Realty Corp. (per the firm, May 2026), marking the group’s first US project. Overseas, Mori holds leasing positions in Shanghai and Jakarta, and operates golf facilities, spas, and country clubs in Japan. Mori Building also runs a dense cultural and hospitality infrastructure: the Mori Art Museum, Tokyo City View, Academyhills, and Andaz and Janu hotels under the Hyatt umbrella. Its philanthropic ventures remain embedded within the corporate structure rather than operating as a separate foundation. In May 2026, the firm announced a concurrent change in representative director, signaling a generational transition at the top. Mori Building differs from most Japanese real estate companies in its refusal to fragment prime districts into single-use silos. It assembles contiguous urban parcels over decades, constructs super-tall mixed-use towers, and retains them as operating assets — a vertically integrated posture that gives it unusual control over the tenant mix and long-term neighborhood economics of central Tokyo.
