Vintage 70s-80s Japanese bedsheet with mushroom design

Vintage mushroom mattress cover from Japan. Elastics on corners to secure on the mattress. These could be removed to use as flat sheet. tag has faded but I think it should fit on a single bed. Orange, yellow, purple and green mushrooms, flowers and bees on a cream background. Thick fabric is very soft and feels a bit like flannel. few faint stains and a bit of piling- see last picture measures approximately 92" x 72"
