THE HEAD OFFICE · GRAND HARBOR · OSAKI, 2018
A harbor where every journey begins
In 2018 the SEGA SAMMY Group brought its head offices, until then scattered across Tokyo, into Sumitomo Fudosan Osaki Garden Tower and named the space “GRAND HARBOR”. Visitors cross a “pier” to a reception counter, wait in a lounge styled as a ship's CABIN, and meet in rooms named after port cities from A to Y. Each floor is about 5,290 m², laid out with as few walls as possible, and executives sit in the open office instead of private rooms.
