Place it at the cut where the Japan destination reveal appears, after a short travel montage and before the Bruh Soundboard Button, then end the sequence with a cheer sound if the reveal is good news for the group.
このサウンドについて
This six-second clip is built around the name Japón, presented as a short standalone sound button rather than a longer scene or song. It gives a listener a brief, offbeat jolt, like a random place name dropped into conversation for comic effect, and that abruptness is what makes it memorable in a feed.
