Japanese sources universally give the date for "Kongō"s keel-laying as 24 September 1875—the same as that for the awarding of the contract—but historian Hans Langerer describes this as improbable, arguing that no shipyard would order enough material to begin construction without cash in hand. "Kongō" was launched on 17 April 1877; the wife of a secretary in the Japanese Legation cut the retaining rope with a hammer and chisel. Completed in January 1878, "Kongō" sailed for Japan on 18 February under the command of a British captain and with a British crew because the IJN was not yet ready for such a long voyage. She arrived in Yokohama on 26 April and was classified as a Third Class Warship on 4 May. On 10 July a formal ceremony was held in Yokohama for the receipt of the ship that was attended by the Meiji Emperor and many senior government officials. The ship was opened for tours by the nobility, their families and invited guests for three days after the ceremony. On 14 July, the general public was allowed to tour the ship for a week.
