Hey Daniel, really glad you responded, it is so interesting to get a feedback from a person who is so close to the culture mentioned above!
Started reading your articles — this topic is worth exploring, that’s for sure.
‘Seven Samurai’ is a terrific movie, I am sure you’ll love it. I’ve heard that it was recently remastered for HD quality, but I am not sure if it would be easier to find. Well, original quality is also ok. Just checked, by the way — in US iTunes store they have HD version available to buy or rent. Probably in Japanese they should have it too! Anyway, good luck finding it :)
Oh, and Japan is such a legendary country! Hope to visit it one day!
