Ugokie Kori no Tatehiki

If you like really old Japanese animation (and you know, even if you don't) watch those two little movies and see how much have changed in the field of animation during last 85 years. Both Ugokie Kori no Tatehiki and Kobu-tori are about some supernatural events shown in a half-joking form. Both black and white. 

Movies from late-20s and early-30s, I guess you should watch more than one of them to get the feeling of this era in animation. And being 10-15 minutes long they let you binge on them pretty easily. Ugokie Kori no Tatehiki and Kaumori are fairytale-like stories featuring samurai and talking animals. They have western feel to them (guess because they look somewhat like early american animation), and yet they are very Japanese, having traditional Japanese music playing as the movies tell us their strange stories. 

For those looking to expand their horizons with early anime.
