Kasagi (笠置?) was the lead ship in the Chitose-class protected cruiser in the Imperial Japanese Navy. It was the sister ship to the Chitose. It should not be confused with the later uncompleted Unryū-class aircraft carrier of the same name, or the Pacific War-era transport Kasuga-maru. It is named after Mount Kasagi, a holy mountain outside Kyoto.


Kasagi was designed and built in Philadelphia, in the United States by William Cramp and Sons (who had also built the Russian cruiser Varyag). Its specifications were very similar to that of the Takasago. It was the first major capital warship to be ordered by the Imperial Japanese Navy to an American shipbuilder.

Service record

For its shakedown cruise, Kasagi was sailed from Philadelphia directly to Great Britain, where its Armstrong cannons were installed. It arrived at Yokosuka on 16 May 1898.

Kasagi was commissioned too late to see service during the First Sino-Japanese War; however, it was used during the Boxer Rebellion to escort Japanese troops and supplies to mainland China. Future admiral Yamashita Gentarō served as executive officer on Kasagi between 1899 and 1900.

During the Russo-Japanese War, Kasagi was active from its base in Korea in the blockade of Port Arthur. It was in the same squadron as the ill-fated battleship Hatsuse, and assisted in efforts to save the crew of that ship when it was mined on 14 May 1904. Later, it fought at the Battle of the Yellow Sea. At the crucial final Battle of Tsushima, Kasagi was commanded by Yamaya Tanin.

After the war, Kasagi was assigned training duties, and made a long distance navigational training voyage from 16 October 1910-6 March 1911 to Hawaii.

During World War I, Kasagi was assigned to the Japanese 1st Fleet, and participated in the Battle of Tsingtao against the Kaiserliche Marine (Imperial Germany Navy).

Kasagi ran aground in heavy weather in the Tsugaru Strait between Honshū and Hokkaidō on 20 July 1916, suffering a major hull breach in the vicinity of its second smoke stack. It was formally written off on 5 November of the same year.
