I was puzzled too. Here's what I came up with.
Going from the Maya reference, "Flyhawk" who I only hear good things about, makes a 1/700 replacement deck for the Aoshima model of that particular ship.
The deck looks like the IJN decks I've seen on models of their "smaller" surface vessels, where the deck is a dark red linoleum with brass straps criss-crossing it and holding everything together.
Here's a build of another kit at the same scale, in this case Pit Road.

I predict success here.
