It would be just too easy if they were identical, mon ami.
The short version is that Kimikawa and Kunikawa Maru had their catapults mounted on sponsons on the aft starboard side, so that the catapult sits right on the edge of the deck. Kamikawa and Kiyokawa Maru had their catapults just inboard of the deck edge, on a deck mounted turntable. Further, all four sisters had different arrangements of the a-c trolley tracks, as seen in the composite arrangement of drawings by Motoyuki Iwashige, and arranged by Luca Ruffato from a discussion on j-ships a couple of years ago. Below (ignore the Sanyo Maru illustration).
Aoshima has released Kimikawa and Kunikawa Maru with identical layouts. However, they have differentiated the layouts between Kamikawa and Kiyokawa Maru.
I'm sure you are thrilled by this news.
Wow... This just ruined my day.. I was like wow I really like these I think I'll build a class of these! ... Nope! I don't know how I'll scratch build the trolley and rails.. Looks like my Kunikawa will be renamed Kimikawa :/.
