Some kaibokans had 81cm mortars, and some transport ships had obsolete artillery pieces with ASW ammo (see AnimeFreak40K  and me above why that didn't really worked), but not 120mm mortars or Type 4 rockets. Maybe some patrol crafts or river monitors had mortars as supplementary weapons, but that's it as far as mortars are concerned.

Artillery rockets were too few and too late in war to find serious naval application. They are suited best for supporting landing operations, and late in war Japanese were on the defensive and didn't really had opportunity to unleash rocket artillery barrages. Besides that wouldn't be much of barrage - I've seen number 500 for total production of Naval Type 4 rockets floating around. Not launchers, mind you, just ammo for them. For comparison single LCT(R) could carry upwards 1000 of RP-3, and allies had dozens of them.

But since we are deep into alternative history anyway, those make sense as weapons of choice for pushing against Abyssal land installations.
