Tamiya, Hasegawa, and I believe Fine Molds, all make 1/350 IJN Destroyer kits. With the lingering bad blood between China and Japan and Dragon really not covering many Japanese subjects in any of their kit lines, I would not hold my breath for them to cover that subject area.
Trumpeter has recently released several RN/RCN 1/30 destroyers, so at least they now finally exist in injection plastic. And yes, it would be nice to see any of the mainstream 1/350 kit makers release an Italian Navy WWII Destroyer class or two in injection plastic.
