Sasebo Naval District
All of the "Myōkō"-class cruisers were assigned to the Sasebo Naval District, forming "Sentai"-4 of the IJN 3rd Fleet, and trained as a unit during the 1930s. During a naval review off Kobe on 26 October 1930 stack gases caused problems on the bridge, resulting in a lengthening of the forward smokestack by two meters.
