"Tsukuba" was laid down on 14 January 1905, launched 26 December 1905 and commissioned on 14 January 1907 at Kure Naval Arsenal, with Captain Takenouchi Heitaro as her chief equipping officer and first captain. Shortly after commissioning, and with Admiral Ijuin Gorō on board, "Tsukuba" was sent on a voyage to the United States to attend the Jamestown Exposition of 1907, the tricentennial celebrations marking the founding of the Jamestown Colony. She then traveled on to Portsmouth, England and returned to Japan via the Indian Ocean, thus circumnavigating the globe.
