[need your help] Japan journey songs

[Draggi]

Hello everyone.
Well, I only have 1 week left in Germany.
On Sunday, 29th I am going to live in Japan for one year.
To celebrate but also to be able to reconnect this time with all of my memories I would like to have a few songs that I am going to hear whenever I travel or have special moments, so that I can remember everything whenever I hear those songs.
They can be chill out songs, but also a bit ballad like or even pop songs.
Perhaps you have something special, like: every season is another song.
It's also okay when there are japanese "traditional sounds" in the song , like in EXILEs "Fireworks".
Please help me out with this.
Thanks in advance.
