The Shinjuku Sumitomo Building, the pioneer of skyscrapers in the Shinjuku subcenter, experienced a rebirth in 2020. It has a large all-weather event space on the premises, as well as a wide variety of restaurants that can be used for a range of occasions, from breakfast to dinner, and specialty stores, making it a convenient and enjoyable place to eat out and shop. We welcome everyone to enjoy it on a daily basis, as well as on their special occasions.
