Tradition and innovation. Lush greenery and a modern building. People and information….
It is a place where various philosophies intersect and become one. What we have aimed for is a new Marunouchi landmark.
We at Mitsubishi Estate Co., Ltd started with “Marunouchi Park Building” and “Mitsubishi Ichigokan”, which comprised the first project of the second stage of our plan to rebuild the Marunouchi district, and now we are aiming to further expand and intensify the reconstruction here and spread these effects throughout Otemachi, Marunouchi and Yurakucho.

The logo mark is modeled on a motif of accumulated bricks and the initials of Brick Square- “BS”. The crossing curves and straight lines represent the mixture of history and modernity, nature and people, and art and business. At the same time the logo represents interactions being born as a new value is projected to the future: the value of the Marunouchi Park Area and the Square itself. The logo type emphasizes “roundness”, “smoothness”, and “space”, and embodies the Brick Square themes of “Timeless Comfort” and “Marunouchi Comfort”.
The colors employed include a brick color for the logo as well as black, chosen for its universality.
The base logo arrangement uses for the logo type imagery of accumulated bricks, and above this is placed a small version of the logo. The arrangement was made with the idea of the “accumulated history of Marunouchi” as well as its “continuing evolutionary development” in mind.

Enclosed by the Marunouchi Park Building, Mitsubishi Ichigokan Museum, Tokyo and the Annex, the tranquil Ichigokan Square is another unique aspect of space utilization that sets the Marunouchi Park Building apart. Beautifully landscaped trees and flowers along the small inviting paths are soothing balm for weary eyes, while an outdoor cafe and art exhibits provide a welcome break for body and soul. At night, gas lamps which have been reproduced from authentic Meiji-era designs gently illuminate the plaza.
The Ichigokan, which was dismantled in 1968 (Showa 43), will be reborn as the Mitsubishi Ichigokan Museum a century after the birth of the Marunouchi office district. Approximately 2.3 million red bricks will be laid, about the same amount as the time of the museum’s original establishment, and the original form of the Meiji and Taisho-era building is reproduced using drawings and materials from that time.
Based on the era when the Ichigokan was established, the Mitsubishi Ichigokan, while focusing on modern art mainly from the nineteenth century, will hold exhibits with themes that are relevant to present times.
The first-floor corner room facing Babasaki Street and Daimyo Koji Crossing is a space that was used as a bank office from the Meiji Era that has been completely reconstructed for use as an open-space cafe with a vaulted ceiling taking up two floors. This is a place where guests can experience the past. Making the best use of the redbrick interior, shops around the cafe will offer a variety of artistic goods for those with refined tastes.
The museum’s logo comes from a design by Kazunari Hattori. Expressing the philosophy “Rebuilding the Mitsubishi Ichigokan and looking back on its origin, we will create a museum for the future”, the museum boasts a brilliant design that is both classic and modern, conceived with a symmetry evocative of Mistubishi’s three-diamond symbol, with “Mitsubishi” at the head, supported by “Ichigokan” and “Museum”.
Collection and Commemorative Opening Exhibition
The main portion of the collection consists of some two hundred posters and lithographic prints by the 19th century French artist Henri de Toulouse-Lautrec. This collection, which is of great importance to the world, was taken by Lautrec from his personal collection and given to Maurice Joyant, an art gallery owner who was Lautrec’s friend.
The Commemorative Opening Exhibition will be “Manet and Modern Paris” (opening April, 2010). We are planning to organize an exhibit on the second half of the 19th century, focusing mainly on Édouard Manet (1832-1883), who took a great deal of inspiration from the evolving modern city of Paris. The exhibit of some one hundred works will include oil paintings, architectural drawings, photographs and other works by Manet and his contemporaries.
