壱岐島
In 1921, "Katori", escorted by "Kashima", carried Crown Prince Hirohito on his tour of Europe where he met King George V. Both ships were disarmed in 1923 and later scrapped to comply with the terms of the Washington Naval Treaty. All of their guns were turned over to the Imperial Japanese Army for use as coastal artillery; two of "Katori"s main-gun turrets were installed around Tokyo Bay and on Iki Island in the Strait of Tsushima. The rest of their guns were placed in reserve and scrapped in 1943.
