This song uses the Japanese Insen scale, which has the same notes as the Phyrgian chord and is used to tune the Koto (a Japanese string instrument).
This song also uses 3 time signatures, god-knows-how-many tempo changes and a bunch of lowpass modulation that caused the track to peak at 32 dB TPM until i moved everything by a few milliseconds.
Most of the song is in 5/4, but i've listed all the tempo markings in pastebin.com/j8JEvuKk
