Sarukani-gassen saru to kani no gassen

An early animated short based on the Japanese folktale. There is some confusion as to which version is which, as there are other animated takes on the tale: 1927s "Yasuji Murata’s Monkey and the Crabs", and 1939s "Monkey and Crabs" or ‘Shin Sarukanigassen’ from Kenzô Masaoka
