If we're going by the picture in the video, I just always figured it was right after a traditional festival of some kind (the 'matsuri' mentioned in the lyrics) and that's why she's wearing traditional dress (it's a common thing especially for girls). It's probably quite late since the matsuri has just ended so she hasn't bothered/had time to change her clothes. There's nothing to explicitly reference her going to a different country, 'saishuubin', translated here as 'last train' can indeed also refer to a flight, but even that doesn't imply she's leaving the country, since domestic flights inside Japan aren't particularly rare. Her carrying a suitcase might also just be that she happens to find it a convenient method of carrying her things when travelling.

Tl;dr: the girl in the picture isn't probably leaving the country and is just wearing traditional clothes because it is literally right after a traditional festival.
