The ships were also each armed with four torpedo tubes in a single quadruple rotating mount amidships for Type 93 (Long Lance) torpedoes; one reload was carried for each tube. The first batch of ships were each equipped with two depth charge throwers for which 54 depth charges were carried.

She returned to Japan and was repaired from 8 November to 16 December 1942. On 19 January 1943, she was torpedoed by USS ''Nautilus'', which flooded a boiler room and her starboard engine room, killing 14 and injuring 64. She was able to steam at 20 knots, and had to resort to emergency steering. She returned to Truk and had to spend from February 2 to 11 March alongside the

She was cut in half and the bridge and forward turrets were removed to lighten ship and replaced with a temporary "wave-cutter" bow. A temporary bridge was constructed behind the mainmast. She was repaired from July to October, receiving the bow from her incomplete sister ship, '' Shimotsuki''. She participated in the
