From the past and to the future


Edo Period
Edo Castle has been the center of Japanese politics, economy and culture since the Edo period.
The business district of Marunouchi used to be lined with residences of feudal lords from various countries who protected Edo Castle and supported the prosperity of the shogunate.


Starting from zero

Acquisition of Marunouchi and the dream of becoming a major business district

The history of Marunouchi started from 1890 when Yanosuke Iwasaki, who was the president of Mitsubishi,
acquire Marunouchi area by the request of the Meiji government.
At that time, the Marunouchi area, which was a wilderness with grown thick grass, was called "Mitsubishigahara."
However, in the background of the acquisition, there was the conviction of Yanosuke that 
"In order for Japan to follow the path of a modern nation, we needed to create a business center like New York or London".

1890s - 1950s

First development

Dawn of a full-fledged business center

Mitsubishi Ichigokan, the first modern office building in the Marunouchi area,
was completed in 1894. After that, a three-story office building made of red bricks
built one after another. The cityscape, reminiscent of London,
was called "Iccho London".
