The Tenryus were completed in 1919 in Navy yards following careful study of the British Caledons. They
were Japan's
first modern light cruisers and
established the precedent of designing such as destroyer
flotilla leaders. Their machinery even consisted of three sets of
destroyer turbines. Succeeding classes of light cruisers closely followed their pattern. However, the Tenryus
were rapidly outclassed by the very destroyers they were intended
to
lead. Their protection was inadequate, being designed only against 4"
(102mm) U.S. destroyer shells, and their range
was inadequate
for Pacific
service. Two of their boilers were of mixed design, capable of burning
either oil or coal. The ships cost ¥4,550,000 apiece.
