About Kaiwo Maru

Kaiwo Maru is the most famous sailing ship in Japan, along with the Nippon Maru. Kaiwo is Japanese for “King of the Sea”. She has lived up to this name by providing the means for arduous traditional sea training. Kaiwo Maru was built in 1989, replacing the former KAIWO MARU which was engaged in the training of merchant marine cadets for over half a century.

She has a sailing rig which looks the same as the old one but is superior in performance because of state-of-the-art naval design, adopting a feathering propeller and other advanced technologies to improve its sailing performance. In the past, the training ship was built to be used only for practical training of merchant marine cadets. However, more recently it is utilized as a classroom at sea and allows for an experiential voyage for general youth and ordinary citizens who become trainees. They won’t be career seamen but will gain valuable knowledge about the ship and the sea, and come to appreciate and respect good seamanship..
