The Anno Mitsumasa Museum is a museum in Tsuwano Town, Shimane Prefecture, dedicated to the works of Anno Mitsumasa, one of Japan’s internationally acclaimed picture-book artists and painters. Anno received the Hans Christian Andersen Award and was also recognized as a Person of Cultural Merit by the Japanese government.
More than simply a place to view artworks, the museum invites visitors into Anno’s imaginative world, where art, mathematics, science, literature, and storytelling come together. Its exhibitions and interactive facilities encourage visitors of all ages to look closely, think creatively, and discover new ways of seeing the world.
The museum building blends naturally into the historic streetscape of Tsuwano. Its exterior features white plaster walls and traditional Sekishu red roof tiles, creating an appearance reminiscent of a traditional Japanese sake brewery.
The calm, traditional design complements the surrounding castle-town architecture while giving the museum its own distinctive character.
Inside the entrance lobby, visitors are greeted by a unique tile design known as a “magic square”, created by Anno Mitsumasa himself. The geometric decoration reflects the artist’s fascination with mathematics and patterns and immediately introduces visitors to the playful and intellectual character of his work.
The museum has two exhibition galleries, displaying approximately 120 works at a time. The collection includes some of Anno’s best-known picture books, such as “Mysterious Pictures” and the “Journey in Pictures” series, as well as “A Picture Book of the Heliocentric Theory.”
The exhibitions also introduce his landscape paintings, book-cover designs, posters, and essays, demonstrating the breadth of his creative activities beyond picture books.
The exhibition displays are changed approximately every three months. This means that returning visitors can encounter different works and discover new aspects of Anno’s artistic world each time.
Anno Mitsumasa’s works are often characterized by delicate watercolor paintings and carefully observed details. Although his pictures may appear gentle and understated at first glance, closer observation reveals numerous details, visual puzzles, and unexpected discoveries.
His deep interest in mathematics, science, and literature can also be seen throughout his work. His art encourages viewers not simply to look at an image but to think about what they see and discover connections hidden within it.
The museum grounds include an annex and learning center where visitors can explore Anno’s creative ideas and the experiences that influenced his artistic career.
These facilities make the museum particularly enjoyable for families, offering opportunities to learn through observation, imagination, and hands-on experiences rather than through conventional exhibitions alone.
The museum’s 50-seat planetarium recreates the night sky above Tsuwano throughout the changing seasons. Visitors can enjoy the stars while learning more about the natural environment of the town and the world of astronomy.
The planetarium also presents original programs incorporating Anno Mitsumasa’s artwork and narration. Programs inspired by “A Picture Book of the Heliocentric Theory” combine astronomy and storytelling, creating an imaginative experience for both children and adults.
The “Old Classroom” recreates a wooden schoolroom inspired by classrooms from the early Showa period. Small desks and chairs are arranged throughout the room, creating a warm and nostalgic atmosphere.
For adults, the space can evoke memories of childhood and a simpler style of education. For children, it offers an opportunity to experience a classroom environment very different from those found in modern schools.
The museum library contains a wide selection of Anno Mitsumasa’s books, international picture books, and art books. Visitors can browse the collection and spend time exploring the books at their own pace.
On the second floor of the annex, a space recreating Anno Mitsumasa’s studio offers a glimpse into his creative environment.
Seeing the setting in which an artist worked provides another perspective on his illustrations and picture books. Visitors can imagine how ideas developed into finished works and gain a deeper appreciation of the thought and sensitivity behind his art.
Anno Mitsumasa was born in Tsuwano in 1926. From an early age, he dreamed of becoming an artist, while also developing a strong interest in mathematics, science, and literature.
After working as a teacher, he became an independent artist at the age of 35. At 42, he published “Mysterious Pictures”, marking his debut as a picture-book artist.
Anno’s distinctive visual style and imaginative approach attracted international attention, and many of his works have been translated and published in countries around the world.
His career extended beyond picture books. He was also active as a book designer and essayist, demonstrating his talent across several creative fields.
A recurring theme throughout his work is the joy of thinking and the pleasure of imagination. These ideas are reflected not only in his individual artworks but throughout the museum itself.
The Anno Mitsumasa Museum is designed to appeal to a wide range of visitors, from young children to adults. In addition to viewing original artworks, visitors can enjoy the planetarium, recreated classroom, library, and other learning facilities.
Families can share the experience of discovering how art can stimulate curiosity and imagination. Children may find playful details within the pictures, while adults can appreciate the mathematical, scientific, literary, and philosophical ideas woven into Anno’s work.
The museum therefore offers more than a conventional art exhibition. It is a place where art, education, imagination, and play come together in an approachable way.
The museum is exceptionally convenient to visit, located approximately one minute on foot from JR Tsuwano Station.
Its location makes it easy to combine with a walking tour of Tsuwano’s historic town center. Visitors can enjoy the museum before or after exploring the traditional streets, historic buildings, waterways, and cultural attractions of the former castle town.
The Anno Mitsumasa Museum is a special place where visitors can encounter art while rediscovering their own curiosity and imagination.
Anno’s gentle watercolors may appear simple at first, but careful observation reveals layers of detail and ideas connected with mathematics, science, literature, and everyday life. His works encourage visitors to slow down, look carefully, and enjoy the process of discovering something unexpected.
With its galleries, planetarium, recreated classroom, library, and studio, the museum offers an experience that goes beyond simply viewing paintings. When visiting Tsuwano, take some time to step inside and explore the rich and imaginative world of Anno Mitsumasa.
