The Nippon Maru is a historic Japanese training vessel now preserved as a museum ship, permanently moored in Yokohama harbor within Nippon Maru Memorial Park. Constructed by Kawasaki Shipbuilding Corporation in Kobe, she was launched on January 27, 1930, alongside her sister ship, Kaiwo Maru. Designed as a four-masted barque, Nippon Maru measures 97 meters (318 feet) in length with a beam of 12.95 meters (42.5 feet) and a draft of 6.90 meters (22.6 feet). Her gross tonnage is 2,286. Originally, Nippon Maru served as a training vessel operated by the Tokyo Institute for Maritime Training to prepare officers for Japan’s merchant marine. She was rigged with 32 sails covering 2,397 square meters (about 25,800 square feet) and was equipped with two 600-horsepower diesel engines for auxiliary power. During her active years as a training ship, she was manned by a crew of 27 officers, 48 seamen, and 120 trainees. During World War II, her sailing rig was removed, and she was repurposed to serve as a training and postwar transport motorship. In 1952, her rig was reinstalled, and she resumed her training voyages until she was replaced in September 1984 by her successor, also named Nippon Maru. Notably, she played a significant role in Japan’s maritime history as a symbol of training excellence and naval tradition. Beyond her maritime service, Nippon Maru has appeared in popular culture, notably in the 2008 film "Superior Ultraman 8 Brothers," where she is depicted as a monument transformed into an interstellar spaceship in an alternate timeline. Today, she stands as a preserved monument, representing Japan’s rich maritime heritage and the evolution of seafaring training vessels.
