Furusato Saisei Nippon no Mukashi-Banashi - 3x34 - 「たぬきの糸車」「二つの月」「姥捨て山」- Followmy.tv

A raccoon comes to a woodcutter's house and learns to work a spinning wheel. On a moonlit night, a giant snake appears with two moons in tow and swallows a hunter. His daughters find out and swear revenge. A lord issues an order that anybody who turns 60 must be left in the mountains to die. A son tearfully takes his mom up to the mountains but can't bear to [do] it. He hides her beneath the floor (this tale is a renewal).
