What they did, though, is change Tokyo from a fu (符) to a to (都). Tokyo is the only to, and there wasn't one before, they came up with it for Tokyo. There were other fus, but there are only two left nowadays: Kyoto-fu and Ōsaka-fu. Why do I mention this? Because Tokyo-to is written 東京都. Kyoto is written 京都. Remember that 東 means East. And yes, there are places in the east of Kyoto that carry the name 東京都 (higashi-Kyoto, higashi being another reading of the character 東). This has to be a troll.
