ww2dbaseThe Akagi was designed as a battlecruiser, much like her American Lexington-class contemporaries. She was converted into an aircraft carrier under the auspices of the 1922 Washington Naval Treaty at a hefty price tag of 53 million Yen (USD$36 million). Based on a battlecruiser, Akagi was a unique looking aircraft carrier. At the time of her construction, there were not many air craft carriers in the navies around the world, hence there were no "standard design" at this early stage, which resulted in her unique configuration: triple-flight deck, unconventional port-side island, and six 8-in guns. Already being the most expensive ship in the Japanese fleet, she underwent an expensive refitting in 1935 that gave her the full-length flight deck configuration that she would enter the Pacific War with. The American pilots identified her as a carrier with a boxy superstructure and an improbably high flight deck that towered six-stories above the main deck.

ww2dbaseAfter the 1935 refitting Akagi became the first Japanese carrier with a modern large flight deck, and it was the operational experiences aboard the Akagi that forged the Japanese naval airpower doctrine. She participated in every major action in the early part of the war, including Pearl Harbor, the attack against Port Darwin, operations in the Indian Ocean, and the Battle of Midway. Unfortunately, with her unique design came an unique weakness as well, and the weakness presented itself during the Battle of Midway. Aside from the fact that her anti-aircraft weaponry were of an older and slow-firing design, they were also positioned poorly. Her anti-aircraft batteries were positioned on the port and starboard sides of the ship, twenty or so feet below the flight deck, therefore guns on each side could only fire at targets on the same side of the ship. Additionally, port side guns are additionally blocked by the island, further reducing the effectiveness of the weapons. This was one of the many reasons why she was fatally attacked at Midway on 4 Jun 1942 at the hands of American dive bombers. The fatal shot was scored by American pilot Lieutenant Richard Best whose bomb landed at the aft edge of the middle elevator. "Nobody pushed his dive steeper or held it longer than Dick," commented Best's backseater James Murray. Best's 1,000-lb bomb crashed through the flight deck and exploded in the upper hangar, instantly killing many Japanese crewmen working in the enclosed hangar and hurling everything from men to aircraft over the edge of the flight deck. When Captain Taijiro Aoki abandoned the ship (he was the last to leave her), she had already been burning for nearly nine hours. He remembered later:

The dive bombers attacked my ship while we were still taking evasive action from the torpedo bombers. We were unable to avoid the dive bombers because we were so occupied in avoiding the torpedo attacks.... We only received two hits.... Akagi was sunk by torpedoes from a Japanese destroyer early next morning because, as a result of the two hits, the whole ship was on fire.

ww2dbaseAkagi took two bomb hits at 1026, tearing into below decks. The most damaging hit on Akagi came in the form of a near miss by Ensign Frederick Thomas Weber, which jammed the ship's port rudder, rendering her essentially unnavigable. Initially refusing to leave the ship, Admiral Chuichi Nagumo, in operational command, was finally convinced by Captain Taijiro Aoki to transfer his flag to another ship after explaining to the admiral that commanding a fleet would be impossible on a burning ship without working radio; they transferred to the light cruiser Nagara. Her engine somehow came back to life at 1203, but it was somewhat useless as she could only sail in circles to starboard due to rudder damage. At 1338, the Emperor's portrait was removed in preparation for abandoning ship, which commenced at 1350. Her hull remained afloat until 0200 the next morning when she was scuttled by two or three torpedoes from one or more of the Destroyer Division Four ships, Arashi, Nowaki, Hagikaze, and Maikaze; Akagi was the first Japanese capital ship in WW2 to be scuttled by her own fellow ships in the Pacific. As she went down, survivors aboard destroyers "Banzai! Akagi banzai!" from the safety of the destroyers.

ww2dbaseAkagi was supposed to have a sister ship, Amagi. The Amagi project was abandoned after her under-construction hull was damaged beyond repair during the Great Kanto Earthquake of 1923.

9 Mar 1942 Akagi returned to Staring Bay, Celebes, Dutch East Indies after the fall of Java.
26 Mar 1942 Akagi departed Staring Bay, Celebes, Dutch East Indies with the Striking Force (less Kaga) together with Battleship Division 3, Cruiser Division 8, and Destroyer Squadron 1 for "Operation C", the raid into the Indian Ocean.
5 Apr 1942 Commander Mitsuo Fuchida of Akagi commanded a 125-aircraft raid against Colombo, Ceylon. Akagi's aircraft helped in the sinking of HMS Cornwall and HMS Dorsetshire.

25 Apr 1942 Captain Taijiro Aoki relieved Captain Hasegawa as the commanding officer of carrier Akagi.
27 May 1942 Akagi departed Hashirajima, Japan at 0600 hours for Battle of Midway as flagship of Vice Admiral Nagumo's Carrier Striking Force (Carrier Divisions 1 and 2).
4 Jun 1942 Akagi launched strikes against Midway Atoll. She was subsequently attacked by numerous enemy land and carrier-based aircraft. At 1026 hours, she was attacked by three aircraft from USS Enterprise, suffering one direct hit amidships in the vicinity of the island, starting a fire in the hangars. A second hit ripped through the fantail and exploded under the port quarter. The third bomb released at her was a near-miss port-side forward. Although normally the damage would had been moderate, the vessel was currently engaged in preparing a strike, with the result that the single bomb hit induced explosions among armed and fueled aircraft within hangars and start a raging aviation gasoline fire. Since she was in a maximum turn at the time, Akagi's rudder was damaged, and soon jammed at 20 degrees to port, leaving her going in wide circles. Unable to command the fleet from her now, at 1046 hours Vice Admiral Chuichi Nagumo transferred flag first to Nowaki, then to Nagara. Akagi's engines worked erratically, with the ship starting and stopping, but she went dead in the water for good at 1350 hours. By 1600 all non-essential personnel had left the ship, though Captain Aoki and a damage control party remained aboard. The vessel burned through the evening and next night, but remained afloat.
5 Jun 1942 Akagi was scuttled by direct order of Combined Fleet chief Admiral Isoroku Yamamoto. At 0520 hours, she sank bow first after two or three torpedo hits out of four fired into her starboard side by Arashio, Hagikaze, Maikaze and Nowaki. She sank in position 30-30 N, 178-40 W. More than 1,070 survivors were rescued, including her skipper Taijiro Aoki, who had replaced Hasegawa in the spring, though he had to be ordered off the ship. Only 263 petty officers and men were lost. Survivors were subsequently transferred from destroyers to Mutsu, one of the battleships in Yamamoto's Main Body. Akagi became the first Japanese capital ship to be scuttled by own ships in the Pacific War.
25 Sep 1942 Akagi was removed from the Japanese Navy List.

The IJN flagship at Midway was Yamato
Akagi was the flagship at Pearl Harbor
8. Commenter identity confirmed David Stubblebine says:

I can find no sources supporting Yamato as the Japanese flagship at Midway, all sources agree that Akagi was the flagship. Nagumo was in overall command and he was aboard Akagi (the very definition of a flagship).

Yamamato was in overall command, the operation was his baby. He was aboard the Yamato.

After James Brown (above) revived this topic, I must walk back by comment of 7 May 2014 that Nagumo was in overall command at Midway aboard Akagi. I had always understood that Yamamoto was the fleet commander aboard his flagship Yamato, which is correct, but I had mistakenly understood that he and Yamato remained in Japan while Nagumo sailed to Midway, which is not correct. Yamamoto and Yamato indeed sailed with the First Fleet, Main Body which stayed 600 miles behind the carrier force commanded by Nagumo. As such, as others have stated all along, Yamamoto aboard Yamato was in overall command of the Japanese forces at Midway while Nagumo aboard Akagi was in tactical command of the carrier force.
