Information regarding IJA Maru Yu submarines

[Harvey 2]

Hi all, 

Currently building Fujimi's 1/350 IJA Transport Submarine Maru Yu as Maru Yu 1. The kit features a transparent side piece to allow for an interior but gives little to detail ot with. I'm attempting to scratch build as much as I can but there is scarce information outside of one or two images on the internet. Wondering if anyone knows what points 2 and 3 are in the blueprints I've found. 2 looks like crew quarters but I couldn't be sure.

Any information or links at all regarding this submarine would be greatly appreciated.

Thanks.
