Mitsubishi Ichigokan Museum

Mitsubishi Ichigokan Museum is an art museum in the Marunouchi district of Tokyo, Japan, housed in a reconstructed Victorian-era brick building. The structure contains three floors above ground and two basement levels that serve as exhibition spaces.

British architect Josiah Conder designed the original structure in 1894 as one of Tokyo's first Western-style office buildings. It was demolished in 1968 and then reconstructed in 2009 using historical building materials and techniques with careful attention to detail.

The name refers to the first building Mitsubishi erected in Japan, reflecting the company's connection to Western architecture during the Meiji era. Visitors today see rotating exhibitions focused on 19th-century European artists, particularly French poster art and painting.

The museum sits roughly five minutes on foot from Tokyo Station's Marunouchi South Exit. The galleries are open Tuesday through Sunday, with Wednesday to Friday offering longer opening hours.

The courtyard features plants that were common in Victorian-era British gardens, including roses and lavender. This planting complements the historical character of the building and creates a quiet atmosphere amid the business district.
