Japanese aircraft carrier Kaga

Kaga (Japanese: 加賀; named after the ancient Kaga Province) was an aircraft carrier built for the Imperial Japanese Navy (IJN). Originally intended to be one of two Tosa-class battleships, Kaga was converted under the terms of the Washington Naval Treaty to an aircraft carrier as the replacement for the battlecruiser Amagi, which had been irreparably damaged during the 1923 Great Kantō earthquake.
