Mitsubishi Building

The Mitsubishi Building is a modern office structure in Marunouchi with expansive windows and contemporary architectural features across its multiple floors. Inside, the building contains office spaces, conference facilities, and numerous dining venues spread throughout its interior.

Completed between 2004 and 2006 by Takenaka Corporation, the structure marks a significant expansion of Mitsubishi Corporation's presence in Tokyo's financial district. It was built during a period when major corporations were strengthening their foothold in Marunouchi.

The building serves as a hub for business activities and international conferences, shaping how the Marunouchi district functions as Tokyo's main financial center. Its role extends beyond corporate offices to hosting major gatherings that bring people together from around the world.

Direct connections through underground passages link the building to multiple subway lines and JR Tokyo Station for convenient access. These passages are especially helpful during bad weather, allowing visitors to move around the area without going outside.

The structure houses approximately twenty restaurants across its levels, offering diverse dining options for visitors and workers. Its conference halls accommodate up to 2,000 people in the main banquet space, demonstrating the versatility of this complex.
