Otagiri vintage Japan hand crafted stoneware coffee mug, mod flowers on pink

Vintage Japan stoneware pottery coffee mug... can't make out the complete mark on this one, but it's a nice heavy handcraft type of piece. It's late 70s or 80s vintage, at our best guess.

This measures 3 3/4" tall, and is in good clean condition without chips or cracks, clean and good without staining.
