Myoko (??) was the name-ship of the 4-member Myoko class of heavy cruisers of the Imperial Japanese Navy—the other ships of the class being the Nachi, Ashigara, and Haguro.
The ships of this class displaced 13300 tons, were 204 metres long, and were capable of 36 knots (67 km/h). They carried one aircraft and their main armament was 10 8 inch (203 mm) guns.
Myoko was laid down at the Yokosuka Naval Arsenal on October 25, 1924, launched and named on April 16, 1927, and was commissioned into the Imperial Navy on July 31, 1929. She was named after a mountain in Niigata prefecture.
She survived the war as a floating battery in Singapore Harbor, and was subsequently towed to the Strait of Malacca and scuttled off Port Swettenham, Malaya near submarines I-501 and I-502.
