Powerful and strong, the Kaiyo Maru is blessed with excellent firepower and crew morale.

The Kaiyo Maru is an impressive vessel: her sheer size sets her apart from other ships. Her coal-fired engine is the main source of propulsion. She is slow moving but incredibly strong, a strength which is backed up with excellent firepower. Her range and accuracy are both good, and the rifle-armed crew members have exceptional morale. Her size means she is most effective in open sea battles rather than close quarter coastal and port battles. The Kaiyo Maru was constructed in the Netherlands at the shipyards of Cornelis Gips and Sons. At the time of launch she was the largest wooden warship ever built in a Dutch shipyard and cost the Shogun and his government 831,200 guilders. She arrived in Japan in 1867 just before the Boshin War. In the autumn of 1868, the original Kaiyo Maru was one of seven ships that carried troops loyal to the Shogun, along with the French military advisor Jules Brunet, to the island of Hokkaido. It was here that they established the Republic of Ezo, the leaders petitioned the Imperial Court to allow them to continue the ways of the samurai on the island. Their request was turned down. This move was swiftly followed by a fleet carrying 7,000 men and, after a crushing defeat at the Battle of Hakodate, the short lived Ezo Republic was no more.
