Yokohama Boat Theatre is one of the only boat theatres in Japan where the company offers a variety of plays. Emphasizing the festive aspect and the commemorative function of theatrical arts letting its spectators revisit their history and identity, the company keeps creating contemporary plays inheriting the essence of performing arts that Japan has been nourishing throughout its history within Asian countries. For this purpose, we especially work on expressing the universe that the Japanese language conceives with its sound, symbolic, choreographic body languages, as well as expressions using masks and dolls in order to let the meanings speak themselves through objects, invoking the imagination of spectators. Yokohama Boat Theatre was founded by the director Takuo Endo in 1981. The company transformed a wooden barge on a river in Yokohama into a theatre, and presented numerous festive plays in the boat theatre such as Oguri Hangan Terute Hime (The Tale of Oguri and Princess Terute) and Mahabharata -The Death of Young Abhimanyu-. Oguri Hangan Terute Hime was performed not only in Japan but also in Asian countries, the U.S, as well as in Europe, and have been internationally recognized. From 2001 on, having transformed a steel barge into a theatre moored at the port of Yokohama, the company presented numerous aspiring plays such as Praise for Kenji, a masked play based on the works of Japanese novelist and poet Kenji Miyazawa, Koi ni Kuruhite (Madly in Love) based on Japanese oral tradition Aigo no Waka, historically performed by wandering Buddhist preachers called sekkyoshi inspired by Japanese ancient ritual 'nagashibina' (letting dolls float away into a river to avoid bad lucks for children) and Indian Pava Kathakali, as well as Farewell America, Endo's autobiographical, poetic drama depicting his dilemmatic, evasive state of mind within comical and tragic transitions of people's beliefs in Postwar Japan. After the director Takuo Endo passed away, Saya Yoshioka took over as the new director, inheriting the company's raison d'être and has been experimenting the art of fusioning masked plays and puppet theatre. The newly-led company has presented Shiroi Kagee (White Shadow Puppet), taking Yoshiro Ishihara as its theme, the poet who had suffered in the Internment in Siberia as war prisoner after World War II, and Inu (The Dog), taking its source from a novel portraying covetous affection between a village girl, a young Muslim officer and a depraved Brahmin during the turbulent war times in Medieval India. We also presented in Tokyo as well as several regions in Northeast Japan Gokuraku Kingyo　(Goldfish in Paradise), written by the former director Endo, inspired by folktales from various regions in Japan. In November 2023, we presented Oguri Hangan Terute Hime (The Tale of Oguri Hangan and Princess Terute) with newly-formed compositions, directions, and casts. In order to make the current boat theatre a more public-friendly art place, our supporters are now working on the project to maintain and manage the boat theatre in a more sustainable manner.
