The twelve Type 41 guns of the "Ise" class were mounted in three pairs of twin-gun, superfiring turrets that were numbered one through six from front to rear. The first pair was forward of the main superstructure, the second pair was amidships, and the last ones were aft of the rear superstructure. The ships' secondary armament consisted of twenty Type3 guns in single mounts. Eighteen of these were mounted in casemates in the forecastle and superstructure and the remaining pair were mounted on the deck above them and protected by gun shields. Anti-aircraft defence was provided by four 40-calibre 3rd Year Type 8-centimetre (3 in) anti-aircraft (AA) guns in single mounts. The ships were also fitted with six submerged torpedo tubes, three on each broadside.
