🗺 Territory

Edo Period（c. 1600–1868）
Core: Japanese archipelago (~377,000 km²)

The Tokugawa shogunate controlled the main islands—Honshu, Kyushu, Shikoku, and parts of Ezo (Hokkaido, limited early control). Authority was exercised through a feudal domain system (han) under centralized shogunal oversight. External expansion was minimal; influence remained internal with tightly restricted foreign contact via Nagasaki.

Meiji Period（c. 1868–1912）
Expansion: ~680,000 km²+

Following the Meiji Restoration, Japan centralized the state and rapidly expanded. Hokkaido was fully integrated, the Ryukyu Kingdom annexed (Okinawa, 1879), Taiwan acquired after the First Sino-Japanese War (1895), and Korea annexed (1910). Japan emerged as an expanding imperial power.
