If you mean the equip themselves it's only +3, if you mean their Firepower stat then that's likely because they are on land so have higher accuracy due to not being tossed around by the sea so they can aim their plunging fire much easier. Every ship in the IJN apart from Yamato and Musashi was vulnerable to plunging fire from 5" guns, even Nagato's deck armour was only 6" at it's thickest giving a reasonable chance of penetration anywhere else. Sometimes even that wasn't enough because Japanese armour wasn't as well made as US or UK armour because of a combination of a lack of resources and metallurgy that wasn't as advanced as their opponents.
