The Marunouchi district is located in the heart of Japan, sandwiched between the Imperial Palace and Tokyo Station. It is a sophisticated area that spans about 1.2 square kilometers.

Four centuries ago during the Edo period, Marunouchi was the site of Edo Castle--home of the shogun--and the entire area was surrounded by a circular moat. The characters maru-no-uchi literally mean “inside the circle”, so the round moat is how the district got its name. The various parcels inside the moat were once occupied by daimyo mansions, but these were cleared out during the Meiji Restoration of 1868 when the land was taken over by the national government. When the government decided to sell it in 1890, the entire parcel was purchased by the second head of the Mitsubishi company, who saw the need for a modern business district that would put Japan on par with the nations of the West. Marunouchi was transformed from an elite samurai quarter to a business hub of red-brick buildings bearing the nickname “The London Block.”

Tokyo Station opened its doors in 1914, and Marunouchi was soon home to many modern American-style buildings as well. This inspired a new nickname: “The New York Block.” Following the Second World War and Japan’s economic boom, modern office buildings began to replace the red-brick structures as area continued to evolve in response to the changing lifestyles leading up to the 21st century.
Before long, the office district diversified into a hub of cosmopolitan exchange, complete with shops, restaurants, museums, hotels, facilities for conferences and events, and more.
The greenspaces adjacent to the Imperial Palace now boast the highest concentration of five-star hotels in Japan. There are also numerous restaurants showcasing the talents of Japan’s top chefs. Marunouchi gives visitors access to unique venues, art museums housing exquisite collections of Japan’s national treasures, jogs through the beautiful Imperial Gardens, and countless other charms.
With so much to offer, the area has become the location of choice for organizers of meetings, incentive tours, conventions, and exhibitions (collectively known as MICE events).
