About
You are the Grand Admiral of the Imperial Japanese Navy during World War II. With your effort, victory is within reach. Issue orders to battleships and other vessels to secure triumph. If things go well, a 500,000-ton battleship might even make an appearance. You can also design non-existent ships, such as a destroyer equipped with 46cm guns. To avoid copyright issues, generic images have been used for historical figures. For convenience, ships completed in 1944 are treated as available in 1941.
