I remember Stephen Burns working that up for a concert several years ago. I don't know if he recorded it but you might want to contact him about it if you don't get any other leads. His website it www.fulcrumpoint.org
Hakan did record it and it's on the "Emotions" CD....Good luck finding it. Marco Blaauw recorded it on his debut CD "Blue". Other then those 2.....non lo so. CG
I managed to dig one up the last time I was in Japan by Kiyonori Sokabe. It is a recording of only new music by Japanese composers, with the Takemitsu as the final track. It's on ALM/Kojima recordings. Good luck with the mute!
