As you may surmise, the series is about a swordsman/gambler traveling around feudal Japan, who happens to be blind.
Some (I think nine) of these films were originally released on DVD by Animeigo, though they went out of print a while ago. When I went to Animeigo’s site to look that up, I noticed that their release of the Lone Wolf & Cub series is also out of print. Could that title likewise be in line for the Criterion treatment?
Release date for Zatoichi is November 26. The listing says it includes 9 Blu-rays and 18 DVDs (don’t know how that breaks down). No word yet on pricing.
