Ibuki (伊吹) was the

Honshū. On 28 August 1912, the Ibukis were re-classified as battlecruisers
.

Design and construction

Problems with her turbine engines delayed the construction of Ibuki, and construction began almost two years later than her sister ship, Kurama, which used standard reciprocating engines. Ibuki was built at Kure Naval Arsenal and was laid down on 22 May 1907, launched on 21 October 1907, and commissioned on 11 November 1907.

Operational history

Shortly after she was commissioned, Ibuki was sent on a voyage to

ANZACs, consisting of 20,000 men and 7,500 horses, across the Indian Ocean
.

At 8.55 the whole fleet moved ahead - thirty-six transports and three escorting cruisers. Two days later, the Ibuki with the great liners Ascanius and Medic carrying troops from South and Western Australia, was found waiting beside the route on the high seas, half-obscured by a rain squall. The two transports took up their places on the line. The Ibuki moved into the Melbourne's position on the starboard beam, while the Melbourne dropped immediately astern of the convoy. The whole fleet then headed for the Cocos Islands.

— C.E.W. Bean, [2]

Ibuki was the only protection for the ANZACs when Sydney participated in the

Kanji Katō[3] had wanted the honor of engaging Emden, but despite being a superior ship to Sydney was ordered to stand down and stay with the convoy. This was later celebrated by the Royal Australian Navy as the "samurai spirit of the Ibuki" whenever Imperial Japanese ships visited Australia in subsequent years.[3]

Fate

After the war, Ibuki fell victim to the

Honshū
and Hokkaidō.
