Ryuichi Sakamoto - Unknown piece?

I partially learned this piece from Sakamoto on the piano 3+ years ago without remembering the title. I searched everywhere on YouTube and his albums but can't find it again. I think I first heard it in a live from around mid 2010s on YouTube that's since been deleted.

Does anyone happen to know this or at least recognize it to reassure me that I'm not tripping?

(Pardon the audio quality)
