Izumi Garden is located in the Roppongi neighborhood of Minato ward, one of the five wards composing Tokyo’s downtown core. The neighborhood, known for its nightlife and expatriate community, is characterized by a hilly topography. The 3.2-hectare (7.9 ac) site area above Roppongi i-chome (“i-chome” means first street) was owned by 60 proprietors and long-term leaseholders. These complications long prevented the site from being redeveloped for better land use.
