The history of Tokyo, the largest metropolis in modern-day Japan, has its roots in ancient times when only scattered Stone Age settlements existed on these lands. However, the true counting of the city's chronology began in the 12th century. It was then that a local warrior, Edo Tara Shigenada, built the first fort here. The name "Edo" itself translates poetically as "entrance to the bay" or "estuary," emphasizing the strategically advantageous position of the small fishing village.
A major milestone was the year 1457, when the feudal lord Ota Dokan founded Edo Castle on the site where the Imperial Palace stands today. This fortress became the core of the future city, gradually expanding with residential quarters and trade routes. In 1590, control over the Kanto region passed to the prominent politician Tokugawa Ieyasu. Under his leadership, massive projects began to drain swamps and level hills, transforming the modest settlement into a powerful administrative center.
In 1603, with the establishment of the Tokugawa Shogunate, Edo effectively became the capital of the country, although Kyoto formally remained so. The city acquired its current name—Tokyo ("Eastern Capital")—only in 1869, when the Imperial Court finally moved to Edo Castle during the Meiji Restoration, marking the beginning of a new era of modernization.
