Place it at the start of a Tokyo sequence, before the main travel footage begins, then follow it with Nico Nico Nii for a Japanese moment and finish with a short reaction sound for the arrival moment.
このサウンドについて
This clip is a single drawn-out vocal call of the word Tokyo, stretched across about eleven seconds into one long, rising shout. It feels playful and over the top, like someone announcing a city with far more enthusiasm than the moment needs. The sound takes its name from Tokyo itself, and that stretched delivery is what makes it easy to recognise.
