The contract for
Izumo, named after the
eponymous province, was signed on 24 September 1897 with
Armstrong Whitworth. The ship was
laid down at their shipyard in
Elswick on 14 May 1899 and
launched on 19 September. She was completed on 25 September 1900 and departed for Japan on 2 October under the command of
Captain , who had been appointed to supervise her construction and bring her back to Japan on 29 September 1899.
Izumo arrived in
Yokosuka on 8 December and Inoue was confirmed in his command.
Russo-Japanese War At the start of the Russo-Japanese War,
Izumo, now under the command of Captain
Miyaoka Naoki, She participated in the
Battle of Port Arthur on 9 February 1904, when
Vice Admiral Tōgō Heihachirō led the
Combined Fleet in an attack on the Russian ships of the
Pacific Squadron anchored just outside
Port Arthur. Tōgō had expected the surprise night attack by his destroyers to be much more successful than it was, anticipating that the Russians would be badly disorganized and weakened, but they had recovered from their surprise and were ready for his attack. The Japanese ships were spotted by the
protected cruiser , which was patrolling offshore and alerted the Russians. Tōgō chose to attack the Russian coastal defenses with his main armament and engage the ships with his secondary guns. Splitting his fire proved to be a poor decision as the Japanese eight- and six-inch guns inflicted little damage on the Russian ships, which concentrated all their fire on the Japanese ships with some effect. Although many ships on both sides were hit, Russian casualties numbered some 150, while the Japanese suffered roughly 90 killed and wounded before Tōgō disengaged. In early March, Kamimura was tasked to take the reinforced 2nd Division north and make a diversion off
Vladivostok. While scouting for Russian ships in the area, the Japanese cruisers bombarded the harbor and defenses of Vladivostok on 6 March to little effect. Upon their return to Japan a few days later, the 2nd Division was ordered to escort the transports ferrying the
Imperial Guards Division to Korea and then to join the ships blockading Port Arthur. Kamimura was ordered north in mid-April to cover the
Sea of Japan and defend the
Korea Strait against any attempt by the Vladivostok Independent Cruiser Squadron, under the command of Rear Admiral
Karl Jessen, to break through and unite with the Pacific Squadron. The two units narrowly missed each other on the 24th in heavy fog and the Japanese proceeded to Vladivostok where they laid several
minefields before arriving back at
Wonsan on the 30th. The division failed to intercept the Russian squadron as it attacked
several transports south of
Okinoshima Island on 15 June due to heavy rain and fog. The Russians sortied again on 30 June and Kamimura finally was able to intercept them the next day near Okinoshima. The light was failing when they were spotted and the Russians were able to disengage in the darkness. Jessen's ships sortied again on 17 July headed for the eastern coast of Japan to act as a diversion and pull Japanese forces out of the Sea of Japan and the
Yellow Sea. The Russian ships passed through
Tsugaru Strait two days later and began capturing ships bound for Japan. The arrival of the Russians off
Tokyo Bay on the 24th caused the
Naval General Staff to order Kamimura to sail for Cape Toi Misaki,
Kyūshū, fearing that Jessen would circumnavigate Japan to reach Port Arthur. Two days later he was ordered north to the
Kii Channel and then to Tokyo Bay on the 28th. The General Staff finally ordered him back to
Tsushima Island on the 30th; later that day he received word that Jessen's ships had passed through the Tsugaru Strait early that morning and reached Vladivostok on 1 August.
Battle off Ulsan On 10 August, the ships at Port Arthur attempted a breakout to Vladivostok, but were turned back in the
Battle of the Yellow Sea. Jessen was ordered to rendezvous with them, but the order was delayed. His three armored cruisers, , , and , had to raise steam, so he did not sortie until the evening of 13 August. By dawn he had reached Tsushima, but turned back when he failed to see any ships from the Port Arthur squadron. north of the island he encountered Kamimura's squadron, which consisted of four modern armored cruisers, , , , and
Izumo. The two squadrons had passed during the night without spotting one another and each had reversed course around first light. This put the Japanese ships astride the Russian route to Vladivostok. Jessen ordered his ships to turn to the northeast when he spotted the Japanese at 05:00 and they followed suit, albeit on a slightly converging course. Both sides opened fire around 05:23 at a range of . The Japanese ships concentrated their fire on
Rurik, the rear ship of the Russian formation. She was hit fairly quickly and began to fall astern of the other two ships. Jessen turned southeast in an attempt to open the range, but this blinded the Russian gunners with the rising sun and prevented any of their broadside guns from bearing on the Japanese. About 06:00, Jessen turned 180° to starboard in an attempt to reach the Korean coast and to allow
Rurik to rejoin the squadron. Kamimura followed suit around 06:10, but turned to port, which opened the range between the squadrons.
Azuma then developed engine problems and the Japanese squadron slowed to conform with her best speed. Firing recommenced at 06:24 and
Rurik was hit three times in the stern, flooding her steering compartment; she had to be steered with her engines. Her speed continued to decrease, further exposing her to Japanese fire, and her steering jammed to port around 06:40. Jessen made another 180° turn in an attempt to interpose his two ships between the Japanese and
Rurik, but the latter ship suddenly turn to starboard and increased speed and passed between Jessen's ships and the Japanese. Kamimura turned 180° as well so that both squadrons were heading southeast on parallel courses, but Jessen quickly made another 180° turn so that they headed on opposing courses. The Russians reversed course for the third time around 07:45 in another attempt to support
Rurik although
Rossia was on fire herself; her fires were extinguished about twenty minutes later. Kamimura circled
Rurik to the south at 08:00 and allowed the other two Russian ships to get to his north and gave them an uncontested route to Vladivostok. Despite this, Jessen turned back once more at 08:15 and ordered
Rurik to make her own way back to Vladivostok before turning north at his maximum speed, about . About this time Kamimura's two elderly protected cruisers, and , were approaching from the south. Their arrival allowed Kamimura to pursue Jessen with all of his armored cruisers while the two new arrivals dealt with
Rurik. They fought a running battle with the Russians for the next hour and a half; scoring enough hits on them to force their speed down to . The Japanese closed to a minimum of about , but Kamimura then opened the range up to . She began repairs at
Sasebo Naval Arsenal in mid-September. On 26 January 1905, Kamimura hoisted his flag again in
Izumo at Sasebo and then escorted several troop convoys to Wonsan on February. On 13 April, the 2nd Division, including the armored cruisers
Tokiwa and , sailed to escort
minelayers as they laid 715
mines off Vladivostok.
Battle of Tsushima As the Russian
2nd and 3rd Pacific Squadrons approached Japan on 27 May, having sailed from the
Baltic Sea, they were spotted by patrolling Japanese ships early that morning, but visibility was limited and radio reception poor. The preliminary reports were enough to cause Tōgō to order his ships to put to sea and the 2nd Division spotted the Russian ships under the command of Vice Admiral
Zinovy Rozhestvensky at around 11:30. Kamimura closed to about a range of before sheering off under fire to join Tōgō's battleships.
Izumo was leading the 2nd Division when Tōgō opened fire on the 2nd Pacific Squadron at 14:10 and, like most of the ships in the division, engaged the battleship which was forced to fall out of formation at 14:50 and sank 20 minutes later. By this time the Russian formation was in disorder and
Knyaz Suvorov suddenly appeared out of the mist at 15:35 at a range of about . All of Kamimura's ships engaged her for five minutes or so with
Azuma and the armored cruiser also firing torpedoes at the Russian ship without effect. After 17:30 Kamimura led his division in a fruitless pursuit of some of the Russian cruisers, leaving Tōgō's battleships to their own devices. He abandoned his chase around 18:03 and turned northwards to rejoin Tōgō. His ships spotted the rear of the Russian battleline around 18:30 and opened fire when the range closed to . Nothing is known of any effect on the Russians and they ceased fire by 19:30 and rejoined Tōgō at 20:08 as night was falling. The surviving Russian ships were spotted the next morning and the Japanese ships opened fire around 10:30, staying beyond the range at which the Russian ships could effectively reply. Rear Admiral
Nikolai Nebogatov therefore decided to surrender his ships as he could neither return fire nor close the range. Over the course of the battle,
Izumo was struck by five large shells, mostly 12-inch, and three smaller shells, mostly 6-inch. They caused only minor damage, although one 12-inch shell, which pierced a boiler uptake, could have disabled all of the middle boilers had it detonated. The shells killed 4 men and wounded 26 others. As the IJN was preparing to invade
Sakhalin Island in early July, Kamimura's 2nd Division, now reduced to
Iwate,
Izumo, and
Tokiwa, was tasked to defend the Korea Strait before it escorted troops that made an
amphibious landing in northeastern Korea. In mid-August, the division covered the landing at
Chongjin, closer to the Russian border. On 20 September 1909, under command of Captain
Takeshita Isamu,
Izumo departed
Yokohama for the
United States to participate in the
Portola Festival at
San Francisco, a citywide fair held on 19–23 October to mark the 140th anniversary of the
Portolà expedition, the first recorded Spanish (and European) land entry and exploration of present-day California, and to proclaim to the world that San Francisco was recovered from its devastating
1906 earthquake.
Lieutenant Prince
Shimazu Tadashige was assigned to the ship during this visit.
Lieutenant Allen B. Reed, engineering officer on the and the future commissioning captain of the heavy cruiser was assigned as Captain Takeshita's escort during the ship's visit at San Francisco.
Izumo made port calls in
Hawaii,
Monterrey,
Santa Barbara, and
San Diego en route.
World War I When Japan declared war on the Central Powers in August 1914,
Izumo was still off the Mexican coast and was ordered to protect Allied shipping there and search for German commerce raiders. On 1 November, the ship, then off San Francisco, was ordered to join a British task force commanded by Admiral Sir
George Patey off
San Clemente Island that included the
battlecruiser and the
light cruiser . After the German gunboat was interned by the Americans on 8 November, the ex-Russian battleship
Hizen and
Asama, which had been patrolling off
Honolulu, Hawaii, to prevent the German ship from leaving, rendezvoused with the other ships of the American Expeditionary Squadron at
Magdalena Bay,
Baja California on 22 November. The squadron, now commanded by Rear Admiral
Moriyama Keizaburo in
Izumo, then headed south to search along the western coast of South America for German ships. On 11 December, after the receiving the news of the British victory in the
Battle of the Falkland Islands, the squadron moved north to search off the western coast of
Central America and then Mexican and U.S. waters in January. During a patrol off the coast of Oregon, the
Izumo picked up an SOS from the
steam schooner Francis H. Leggett, but did not provide aid due to the presence of a German cruiser nearby. The
Leggett later sank, with only 2 survivors out of 62 on board. While searching Baja California,
Asama was badly damaged when she struck an uncharted rock on 31 January.
Izumo, delayed by poor communications, arrived on 12 February and Moriyama radioed for
repair and
salvage ships to be sent from Japan.
Izumo was relieved by
Tokiwa on 19 March and the ship returned home. including a circumnavigation of the globe from August 1921 to April 1922 with
Yakumo. Two of the naval cadets that participated in this cruise were Princes
Kuni Asaakira and
Kachō Hirotada. While in
Vancouver,
British Columbia, on 7 February 1925, on one of these cruises, a
tugboat collided with one of the ship's boats at night, drowning 11 crewmen. In 1935 her boilers were replaced by six
Kampon water-tube boilers with an output of only which reduced her top speed to . She now carried of coal and of
fuel oil which increased her deep displacement to . In 1934,
Izumo was equipped to operate a
floatplane at the Sasebo Naval Arsenal.
Izumos
Nakajima E4N floatplane and another from the light cruiser managed to get into the air and they claimed to have shot down one
Curtiss Hawk biplane fighter and a
Northrop Gamma bomber. Two days later, her E4N claimed to have shot down another Hawk.
Izumo was attacked that same day by a
Chinese torpedo boat, but the torpedoes missed and the boat was abandoned by its crew. The ship provided
naval gunfire support to Japanese troops ashore during the battle.
Izumo was repeatedly attacked without effect by Chinese aircraft for the duration of the Battle of Shanghai. On 31 December, the cruiser struck a mine in
Lingayen Gulf while supporting Japanese forces during the
Philippines Campaign. She was towed to
Hong Kong in February 1942 for repairs.
Izumo was re-classified as a 1st-class cruiser on 1 July. for the
Kure Naval District.
Izumo was not attacked on the first day of the American aerial
attack on Kure on 24 July 1945, but she was near missed three times four days later. The shockwave from the detonations sprang the ship's seams and the resulting flooding caused her to
capsize at coordinates . She was removed from the
navy list on 20 November and her
hulk was raised and scrapped in 1947 by the
Harima Dock Company. ==Notes==
