Maybe try on cgpeers ?

I post again, maybe someone can help me, I've been looking for them for ages...
Documentaries/making ofs of Akira Kurosawa's films called
Toho Masterworks serie "It's Wonderful to create", Episodes 1 to 6 :
Sugata Sanshiro (25m)
The Most Beautiful (20m)
Sugata Sanshiro Part II (20m)
The Men Who Tread on the Tiger's Tail (23m)
No Regrets for Our Youth (22m)
One Wonderful Sunday (28m)

They should be included in the Masterworks Japanese edition DVD and/or Blu-ray of Kurosawa's films (they were made in 2003). The other episodes are either available on the Criterion editions or on the new Wild Side Digibooks of AK's films. Anyway, is there any place where there's a rip of the Masterworks Boxset ? Maybe on PTP or Asian DVD Club ?
Many thx in advance !
