30 May 1942:
CruDiv 7 and DesDiv 8 rendezvous with the Transport Group and oiler NICHIEI MARU.
5 June 1942: Operation "MI" - The Battle of Midway:
The Commander-in-Chief of the Combined Fleet, Admiral (Fleet Admiral, posthumously) Yamamoto Isoroku (former CO of AKAGI) 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 the 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 the 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.
After learning about the collision, the Commander of the Second Fleet, Vice Admiral (later Admiral) Kondo Nobutake (former CO of KONGO) orders Vice Admiral Kurita to have DesDiv 8's ARASHIO and ASASHIO stay behind and escort MOGAMI and MIKUMA. Flagship KUMANO and SUZUYA are detached. The MOGAMI group proceeds westward at reduced speed.
A notice is published on board MIKUMA that the Midway attack has been abandoned and that CruDiv 7 will operate with BatDiv 1.
At 0534, retiring MIKUMA and MOGAMI are bombed from high altitude by eight Boeing B-17 "Flying Fortresses" from Midway, but they score no hits. At 0805, USMC Captain Richard E. Fleming's (MOH posthumously) Scout-Bombing Squadron 241's six Douglas SBD "Dauntless" dive-bombers and six Vought-Sikorsky SB2U "Vindicators" from the 2nd Marine Air Wing on Midway attack MIKUMA and MOGAMI but they only achieve several near-misses.
6 June 1942:
MIKUMA and MOGAMI are heading for Wake Island when they are attacked by three waves of 81 SBD dive-bombers from USS ENTERPRISE (CV-6) and the HORNET (CV-8). ARASHIO and ASASHIO are each hit by a bomb. MOGAMI is hit by six bombs.
MIKUMA is hit by at least five bombs in the forecastle, bridge area and amidships and set afire. The hit on the forecastle puts the forward guns out of commission. The hit near the bridge area sets off some ready service AA shells and causes considerable damage to the bridge and personnel. The hit amidships sets off several torpedoes and the resultant explosions destroy the ship. Captain Sakiyama is wounded severely. MIKUMA turns on her portside and sinks at 29-22N, 176-34E. 650 crewmen are killed.
ASASHIO rescues Captain Sakiyama. Later, he is transferred to SUZUYA for medical attention. MOGAMI, ASASHIO and ARASHIO rescue 240 survivors, then they depart for Truk.
Later, Admiral Kondo orders ASASHIO back to search for more survivors from MIKUMA and to scuttle her. She searches, but fails to find the cruiser.
8 June 1942:
MOGAMI rejoins CruDiv 7.
9 June 1942:
USS TROUT (SS-202) passes through a large oil slick and some debris, then rescues Chief Radioman Yoshida Katsuichi and Fireman, Third Class Ishikawa Kenichi of MIKUMA from a large wooden hatch cover. TROUT takes them to Pearl Harbor as POWs five days later.
12 June 1942:
Captain Sakiyama dies aboard SUZUYA. He is promoted Rear Admiral, posthumously.
10 August 1942:
Removed from the Navy List.
 Mt. Niitaka, located in Formosa (now Taiwan), was the highest point in the Japanese Empire at the time.
 See "Naval Alamo"for more about the 1942 naval battles off Java.
 It has been suggested, but not yet verified, that SUZUYA turned back and removed the remainder of MIKUMA's crew, including Captain Sakiyama. Then SUZUYA scuttled MIKUMA with torpedoes.
