The sail training ship "Nippon Maru" was launched 85 years ago this January 27th, and on April 29th marked the thirtieth anniversary of its opening to the public in Yokohama. While still active the ship was used to train seafarers, but since coming to Yokohama it has continued to contribute to ocean education for youth through its on-board training Ocean Classroom. The Yokohama Port Museum, operating in conjunction with the Nippon Maru, has been carrying out educational outreach programs focusing on the ocean, port, and ships for elementary level students since its opening in 1989.
