Combat experience in the First Sino-Japanese War of 1894–1895 convinced the Imperial Japanese Navy of weaknesses in the Jeune Ecole naval philosophy, which emphasized torpedo boats and commerce raiding to offset expensive heavily armoured ships, and Japan embarked on a program to modernize and expand its fleet in preparation for further confrontations.
In particular, Japan promulgated a ten-year naval build-up programme, with the construction of six battleships and six armoured cruisers at its core.
These ships were paid for from the £30,000,000 indemnity paid by China after losing the First Sino-Japanese War.

As with the earlier Fuji and Shikishima-class battleships, Japan lacked the technology and capability to construct its own battleships, and turned again to the United Kingdom for the four remaining battleships of the programme.
Mikasa, the last of these ships, was ordered from the Vickers shipyard in Barrow-in-Furness in 1898 at the cost of £880,000 (8.8 million yen at that time).
Although she closely resembled several of the other ships ordered in this program, she was the only ship in her class.
