How many Takemitsu piano recordings are there?

I love Toru Takemitsu's pieces for solo piano dearly, more than any of his other work. It is strange to me that so few recordings are on the market of this great material. I have seen (and own) the Woodward and the Serkin performances, and I know that there was a box set a few years back, but I have not been able to find a complete one. Does anyone know of any other performances at all?
