This is a real wooden deck, designed as an exact replica of the deck on the real IJN battleship Yamato! It's pre-cut and ready for use. Note, though, that because it matches the real Yamato's deck, it will need some alteration if used on a kit that differs slightly from the real Yamato; for instance, the deck of Tamiya's 1/350 kit is slightly different from that of the real thing, so this wooden deck will need some alteration if used with that kit.
