The radical and the meaning of this kanji are almost the same! The radical is sword, but we're learning Japanese, so can you name a Japanese sword? That's right, the most common is a katana, which happens to be the meaning of this kanji as well.
So now you have this sweet katana in your hands and you're swinging it around like an idiot. Feel free to make whooshing noises as you swing it around. To become a master katana wielder, you decide to travel to とうきょう (That's Tokyo!). とうきょう has the best sword and katana schools in the world, so it makes sense to travel to とうきょう.
