Modifications

By 1945 the ships had 9 to 14 25mm/60 gunsand their speed was down to 12 knots

The Idzumos were obsolete armored cruisers, veterans of the Russo-Japanese War of 1905, and very heavily protected for 8" gun cruisers. They were serving as coastal defense ships with China Area Fleet at the time of the Pearl Harbor attack, and may possibly have had their armament reduced to a few 6"guns by then.
