Ikoma (生駒) was the second vessel in the two-ship Tsukuba class of armoured cruisers in the Imperial Japanese Navy.

[2] These were the first major capital ships to be designed and constructed entirely by Japan in a Japanese shipyard, albeit with imported weaponry and numerous components.

Shortly after commissioning at the Kure Naval Arsenal, Ikoma escorted the United States Navy’s Great White Fleet through Japanese waters on its around-the-world voyage in October 1908.

From 1 November 1914 to 17 January 1915, Ikoma was based out of Hong Kong, Singapore and Townsville, Australia, protecting British colonies and shipping from German commerce raiders.

Ikoma was a victim of the Washington Naval Agreement of 1922 and was scrapped at Mitsubishi Heavy Industries Nagasaki shipyards in compliance with that accord.
