The kit instructions show the single landing craft provided to be mounted on the deck. I am then curious what is leading you to believe there were any folding landing craft? All the info I have found says one, or two, landing craft were carried on the deck, as unlikely as that might seem.
The kit's instructions are contained here: https://www.1999.co.jp/eng/m/10223410
They show that--if you want to add the landing craft-- you put part C24 over the exterior cargo space, and mount the craft to it. C24 is not a folded up landing craft. It is a mounting plate for the landing craft.
This link has general info on the subs, and shows a drawing of them with two landing craft mounted (and aft guns removed) : http://www.navypedia.org/ships/japan/jap_ss_d1.htm
The specific type of landing craft supplied in the kit looks like a Moku Daihatsu landing craft. Some details on that here: https://www.barrageminiatures.com/boats/207--moku-daihatsu-class-landing-craft-156-28mm.html

Note that the Moku Daihatsu was a 15 meter craft, while the specs call for 14 meter Daihatsu (the standard steel type.) However, that is not what the kit supplied item looks like. To me, it looks like a Moku Daihatsu. FWIW
(Can tell you nothing of the round object at the bow. Has been asked here before with no answer provided.)
Hi, i am building Aoshima 1/350 IJN Type D Submarine. but i am really confused about the whole landing craft concept. And the lack of information of these submarines.
The boats were supposed to carry two landing crafts for tranferring cargo ashore.
- So fahr so good.
But it is really difficult to learn anything about these Landing crafts, - as fahr as i can tell these were of a special collapsible tybe, which when collapsed and laying mirrored on the side, would fit into a wide slit in the deckstructure in the rear of the submarine.
But i do not know if this is a fact or these landing crafts were simply attached on top of the deck, (which for me seems very unlikely!)
This is never the less how it is shown in the Aoshima manual.
An other mystery is the strange round object below (or in fact part of) the bow of the submarine. Maybe it could have something to do with the listening device located behind?
any help would be most welcome!
