Japanese expeditions refer to various historical journeys undertaken by Japan, particularly during the Age of Exploration and the Meiji Restoration. These expeditions aimed to expand trade, gather knowledge, and establish diplomatic relations with other nations. Notable examples include the Black Ships led by Commodore Matthew Perry in 1853, which opened Japan to Western trade. In addition to maritime expeditions, Japan also engaged in military campaigns, such as the Sino-Japanese War and the Russo-Japanese War. These conflicts were significant in establishing Japan as a formidable power in Asia, showcasing its military capabilities and leading to territorial expansion.
