With a wide variety of excellent 1:700 scale plastic kits of IJN Japanese destroyers available, the question comes on what items deserve to have their plastic parts replaced with brass photo-etch. One piece of equipment readily jumps to mind, the depth charge racks. With Lion Roar set R7029 you have the set necessary to accomplish this refit.
The set comes with stern racks, different pattern side racks including loading davits and Y guns. Lion Roar even throws in depth charge end caps that are relief-etched. All the modeler has to do is cut the depth charge cylinders from plastic rod and fit the caps.
