This very impressive Kurosawa box set is being released by The Criterion Collection in December. A word from Criterion about the set:

In 2010, the film world will celebrate a momentous event: the hundredth birthday of Akira Kurosawa, whose influence on cinema has been incalculable and whose staggering catalog of masterpieces—from Rashomon to Seven Samurai to Kagemusha —has remained fresh and timeless with each passing year. To do our part, we’re presenting a deluxe, linen-bound collector’s set, AK 100: 25 Films by Akira Kurosawa, just in time for the holidays. AK 100, the most extensive set of the filmmaker’s works ever released in this country, also includes five films new to Criterion collectors: four early rarities never before released here on DVD (Sanshiro Sugata; Sanshiro Sugata, Part Two; The Most Beautiful; and The Men Who Tread on the Tiger’s Tail) and his poignant final film, Madadayo. And as a companion to the films, we’ve created a hardbound, illustrated, ninety-six-page book featuring new writing by Stephen Prince and Donald Richie. Supplies are limited, so preorder your copy of what is sure to be the cinematic gift of the season now. Happy viewing!
