The form of imperialism that Commodore Perry's arrival in Japan created was gunboat diplomacy. This refers to the use of military force or the threat of force to achieve diplomatic objectives. Perry arrived in Japan with a squadron of warships and demanded that Japan open its ports to foreign trade, using the presence of his powerful naval vessels as leverage to negotiate on behalf of the United States. This ultimately led to the opening of Japan to Western influence and trade.
