The mole has a knife ready for your arrival. You get out of your airplane, you step on the ground and... ouch! You stepped right on the knife, and there's the mole, sticking it out of the ground. "I checked the schedule for your arrival!" it squeaks happily, and disappears.

Your arrival to とうきょう is now ruined. And your next stop is now going to be an arrival at a とうきょう hospital to get this mole knife out.
