Two recent additions to Rising Decals impressive Japanese aircraft repertoire (but get them while you can!) are 72-046 The Birds of the Manchukuo in 1/72nd scale and 48-015 Zero in 1/48th scale.
The Manchukuo set is a neat and colourful package that provides markings for four Ki-27 "Nates" and two yellow Ki-9 biplane trainers. Two of the Nates and both Ki-9's have the distinctive 'Gokoku' fuselage legends and all six aircraft have tail markings. One of the Nates has had the former JAAF fuselage Hinomaru removed leaving a patch of bare metal that will make an interesting painting proposition. The 3rd Hikotai example is depicted with a yellow fuselage band which I think might just have been an over-painted former JAAF white senchi-hiyoshiki "combat stripe", a marking not carried in Manchukuo service.
The Zero set in 1/48th has some interesting examples including a dark green A6M2 with interesting triangular tail marking, an A6M2 bomb carrier, two A6M2 in field applied blotch and mottle camouflage schemes, an A6M2 with 'Houkoku' presentation markings and two 'Houkoku' adorned A6M3, one with yellow wing leading edge IFF strips and red fuselage chevrons. Plenty here to choose from and ideal for dressing up those older kits in the stash like the Fujimi or Tamiya A6M2 or the Tamiya A6M3. A similar but expanded Zero set in 1/72nd scale is due soon.
AZ Models are about to release a 1/72nd scale 'Kikka' IJN jet in three boxings - actual, what-if day fighter and a what-if nightfighter - with oblique cannon.
