#8: Edo → Tokyo (Japan)
When Emperor Meiji moved his court east in 1868, he didn’t just relocate a capital; he renamed the future. The old city of Edo, a samurai stronghold, became “Tokyo,” meaning “Eastern Capital.” It was symbolic of a country turning toward modernization after centuries of isolation. The change mirrored Japan’s transformation from feudal to industrial, from inward to outward-looking.
It’s hard to imagine the megacity by any other name. Tokyo became the shorthand for progress itself; an idea as much as a place.
