A week or so back there were some questions about Japanese subminitions and how many types there were. In several years of research I have found information on the following Japanese designs:
1/3rd kg submunition, HEAT three tail variations
.4kg submunition, aka: Bolo Bomb, Para Bomb or Para Cable Bomb
1/2 kg, two body variations, three fuze variations
1 kg submunition, HEAT
1 kg HE (Naval)
1 Kg submunition, incendiary - appears to be a loose copy of the German 1kg, only one rough photo found to date
Steel Phosphorus pellets for 30 and 60kg incendiary bombs
HE submunition for 70mm Anti-aircraft barrage mortar
This is all I have found to day, with the possible exception of the 1kg incendiary all appear to have been considered as standard items. I've attached photos of some of mine from the collection. L-R 1kg HEAT, 1/3rdkg HEAT (2), 1kg HE, two 1/2kg HE with fuze variations. The second photograph is of the small HE submunition for the barrage mortar, mine does not have the parachute attached. I have also attached a historic photo found in the US National Archive showing the uncovering of a dudded dispenser of the 1kg HEAT submunitions, located in New Guinea.
