Modifications
1943: Two 5.5" guns removed. Torpedo armament increased to 4x4 mounts.  Light antiaircraft increased to 22 25mm/60 AA guns and 2 13mm/76 AA guns and Type 21 radar installed.

1944-9: Isuzu converted to antiaircraft cruiser with 3x2 5"/50 DP guns, 11x3, 5x1 25mm guns, and 2x2 torpedo tubes.


The Nagaras were completed in 1922-25 and resembled the earlier Kumas except for their 24” (61 cm) torpedo armament. Though these were not originally capable of firing the deadly Long Lance, which required special equipment to handle their pure oxygen supply, the class was in the process of having its torpedo tubes updated at the outbreak of war.  The conning tower was left unarmored to make room for aircraft handling facilities.

In late 1944, Isuzu was converted to an antiaircraft cruiser intended to serve as the flagship of an antisubmarine group.
