Japanese battleship Ise
On 12 April 1922, while at Yokohama, "Ise" hosted a delegation which included the Prince of Wales (the future King Edward VIII), who was accompanied by his second cousin, the future Lord Mountbatten of Burma. Captain Kanna Norikazu relieved Nagasawa on 1 December. The ship aided survivors of the Great Kantō earthquake in September 1923. From the early 1920s through the late 1930s, "Ise" mostly cruised off the coast of China. Little detailed information is available about her activities during the 1920s, although she helped sink the obsolete destroyer during gunnery training on 10 August 1926. The ship was overhauled in 1928–1929, during which her forward superstructure was enlarged and her aviation facilities improved.
