Having repeatedly seen and enjoyed this video and having visited many sites in Japan, where scenes were filmed, I find it a classic portrayal of historical life in feudal Japan.
Visiting the various castles (many hundreds of years old and still in superb condition), plus ryokan, bath-houses and Samurai homes of great vintage, this video set so well displays the atmosphere of the times that one can visualise the battles and human struggles/relationships as one tours.
Much, much better, than the 2 hour movie.
