Admiral (Fleet Admiral, posthumously) Yamamoto Isoroku (former CO of AKAGI), CINC, Combined Fleet, orders Midway to be shelled. CruDiv 7 is tasked to accomplish the shelling at 1050 (I). CruDiv 7 and DesDiv 8 are 410 miles away from the island, so they make a high-speed dash at 35 knots. The sea is choppy and the destroyers lag behind. At 2120, the order is canceled.
At 2138, flagship KUMANO spots surfaced submarine USS TAMBOR (SS-198). KUMANO signals a 45° simultaneous turn to starboard to avoid possible torpedoes. The emergency turn is correctly executed by flagship and SUZUYA, but the third ship in the line, MIKUMA, erroneously makes a 90° turn. Behind her, MOGAMI turns 45° as commanded. MOGAMI's navigator, LtCdr (later Captain) Yamauchi Masaki, watching SUZUYA does not see MIKUMA's movement. This results in a collision in which MOGAMI rams MIKUMA´s portside below the bridge. MOGAMI's bow caves in and she is badly damaged. MIKUMA's portside oil tanks rupture and she begins to spill oil, but otherwise her damage is slight.

25 October 1944: The Battle off Samar:
SUZUYA engages Task Group 77. 4. 3's “Jeep” carriers, but is attacked by ten TBM Avenger torpedo-bombers. A near-miss by a bomb causes the loss of her port propeller and her speed falls off to 20 knots. At 0830, Vice Admiral Shiraishi transfers his flag to SUZUYA from KUMANO that was damaged heavily in earlier attacks by aircraft.
At 1050, SUZUYA is attacked by 30 other carrier aircraft. A near-miss to starboard by a bomb sets off SUZUYA's No. 1 torpedo tubes loaded with oxygen-propelled Type 93 "Long Lance" torpedoes. At 1100, additional torpedoes start to explode. The fire and blasts damage the starboard engine rooms and the No. 7 boiler room. SUZUYA becomes unnavigable. At 1105, destroyer OKINAMI is ordered to assist SUZUYA. At 1130, Vice Admiral Shiraishi again transfers his flag, this time to TONE.
At noon, SUZUYA's remaining torpedoes and ammunition explode. At 1150, Abandon Ship is ordered. At 1315, SUZUYA turns on her starboard side. At 1322, she sinks at 11-45.2N, 126-11.2E. Captain Teraoka and 401 officers and men are rescued by OKINAMI.
20 December 1944:
Removed from the Navy List.
 Mt. Niitaka, located in Formosa (now Taiwan), was the highest point in the Japanese Empire at the time.
 It has been suggested, but not verified, that SUZUYA turned back and removed the remainder of MIKUMA's crew including Captain Sakiyama. Then SUZUYA scuttled MIKUMA with torpedoes.
