Idemitsu Museum of Arts, Tokyo

The Idemitsu Museum of Arts is situated in the Marunouchi area of Chiyoda, Tokyo. It was established to showcase the extensive art collection amassed by Sazō Idemitsu, the founder of the Idemitsu Kōsan oil company, over a period of 70 years. This museum was founded in 1966 and is run as an incorporated foundation under the umbrella of Idemitsu Kōsan.

In 2019, the museum made a significant acquisition of 190 artworks, primarily paintings dating from the Edo period, from American collectors Joe and Etsuko Price. Some notable pieces from this acquisition include Itō Jakuchū's "Birds and Animals in the Flower Garden," Maruyama Okyo's "Tiger," and Sakai Hōitsu's "The Thirty-six Poetic Immortals," among others. The Prices are renowned collectors of Edo period paintings, and a portion of their collection is housed at the Los Angeles County Museum of Art.

The Teigeki Building, which currently houses the museum, is showing signs of aging and is scheduled for reconstruction. Consequently, the museum is set to temporarily close its doors in 2025 and reopen once the construction work is completed.

The museum's collection encompasses a wide range of Japanese paintings and East Asian ceramics, including modern works like paintings by Misai Kosugi and ceramics by Itaya Hazan. Additionally, Western paintings by artists such as Georges Rouault and Sam Francis are also part of the collection.

The museum boasts an impressive collection of approximately 15,000 cultural artifacts, with the Japanese government designating two items as National Treasures and 57 as Important Cultural Properties. One of these National Treasures is the Ban Dainagon Ekotoba. Additionally, the museum hosts several temporary exhibitions throughout the year.
