Shortly after she was commissioned,
Ibuki was sent on a voyage to
Thailand to attend the
coronation ceremony of the Thai king
Rama VI Vajiravudh.
Ibuki served in
World War I, participating in the hunt for the
German light cruiser in 1914. She escorted a convoy of 10 troop transports carrying the main body of the New Zealand Expeditionary Force, crossing the
Tasman Sea with the
British protected cruiser and armoured cruiser to
Albany,
Western Australia in November 1914. Together with the
Australian light cruiser ,
Ibuki escorted the
Australian Imperial Force (AIF), consisting of 20,000 men and 7,500 horses, across the
Indian Ocean.
Ibuki was the only protection for the ANZACs when
Sydney participated in the
Battle of Cocos. The commander of
Ibuki, Captain
Kanji Katō 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. ==Fate==
