Mitsubishi Estate is planning a 400 meter tall office building for an area just north of Tokyo Station. This is the largest development planned for the Otemachi/Marunouchi area, and when complete it will be the tallest building in Japan, exceeding the 300m tall Abeno Harukas in Osaka.
Mitsubishi is aiming to make the building an international centre for finance, and hope to attract both domestic and foreign financial institutions.
