  • Seikado was founded in 1892 (Meiji 25) by Yanosuke Iwasaki, the second President of Mitsubishi, and then expanded by his eldest son Koyata, the fourth President. It is home to roughly 200,000 volumes of classical Japanese and Chinese texts, including seven National Treasures, and 84 Important Cultural Properties, as well as around 6,500 antique items from the Orient.

    This new art museum, Seikado Bunko Art Museum, has opened in Marunouchi, a place with strong ties to Mitsubishi. Visitors can see firsthand and up close the National Treasure “Yohen Tenmoku (Inaba Tenmoku)”, as well as ceramic works, paintings, tea ceremony utensils, swords sculptures, and other works of art in an expansive range of genres and styles.

Exhibitions & Events

  • The “Perfect Guide to Japanese Swords,” Revived:
    Studying the Great Swords of the Kamakura Period

    Exhibition Period
    Saturday, June 22 - Sunday, August 25, 2024

    “The Absolute Beginner’s Introduction to Japanese Swords”, a past hit in Setagaya’s Okamoto area, is back again!

    The Japanese sword, often called the “soul of the samurai”, has been used as a weapon and also appreciated as a work of art for around 1,000 years. Now that we’re in the midst of a surge in the popularity of swords, if you don’t want to find yourself saying, “They all look the same,” or, “I don’t know where to look,” or you want to take a fresh look at the basics of the Katana, then this is the introductory course for you!

    This exhibition, the first of its kind in Marunouchi, showcases nine National Treasures and Important Cultural Properties from the museum’s own collection, as well as ancient masterpieces from times ranging from the Heian Period (794-1185) to the Nanbokucho Period (1336-1392), with a particular focus on the Kamakura Period (1185-1333), which is known as the “Golden Age of Japanese Swords”. Furthermore, there will also be a special display of seven standing wooden statues of the Twelve Divine Generals, which are Important Cultural properties and some of the most famous examples of Buddhist statues from the Kamakura Period.

What is Seikado?

  • Seikado, which is celebrating the 130th anniversary of its founding, has relocated its art gallery from the Okamoto district of Setagaya to the first floor of Meiji Seimeikan (completed in 1934 (Showa 9), National Important Cultural Property located in Marunouchi alongside the Imperial Palace moat.
    The works beckon visitors with their mutually complementary beauty in four exhibition rooms face each other in a way that surrounds the foyer (atrium in the central lobby), where natural light shines in through skylights in the high ceiling, in a space with stately beauty that makes generous use of marble in a manner typical of the contemporary stylings of the early Showa Era.
    In the middle of the third decade of the Meiji Era, Yanosuke Iwasaki was working on a project to build a district of Mitsubishi office buildings in Marunouchi, with the hopes of creating a “museum” in one corner of the area. The dream of the founders, held for more than 100 years, are now coming to fruition.
