Mitsui O.S.K. Lines is inviting today's kids, the future of Japan, onboard the Nippon Maru, to have fun while learning about ships, maritime transport work, the ocean around Japan, and the ocean environment. Over the course of four events we have been able to provide this learning experience for more than 600 children, out of the 2,540 who applied. For both the volunteers and shipping company that supported the cruise, it has also been a good opportunity for self-examination and improvement.
