Ships, being relatively small and close-quartered, have no true dojos. Instead, they have the armory, housed at the fore of the ship's hold. Containing all those materials a warrior would need to treat their weapons and armor against the salt as well as a tiny shrine to Bishamon, this small area can hold no more than four samurai in practice at a time. Ordinarily, those seeking exercise take it on the deck where room is greater but any true matches, including any duels that may need to be fought if tempers bypass good sense, take place here.
