Nostalgic Song

The song takes me straight back to this kind of scene (view of
the houses across the road from our house in Tokyo).

I just clicked on this link, ah nostalgia (or natsukashii in Japanese). 

It is the Tokyo sunset song, the song we hear played over the loudspeakers every night we're in Tokyo. From what I gather, a song is played in most towns across Japan (read the article for the dual reasons), but the song differs from place to place.
