The International House of Japan

The International House of Japan, also known as “I-House,” is home to a non-profit organization founded in 1952 to promote intercultural exchange. I-House is located in the heart of the mixed-use Roppongi Hills complex, close to many of the major Tokyo embassies. The venue offers a number of banquet halls and rooms on nearly 11,000 square meters of land, including an auditorium and seven additional meeting rooms. A tranquil facility in the heart of the city, all banquet rooms adjoin the large, 19th century garden, enabling guests to mingle freely both indoors and out. There are also a cafe and a restaurant.
