Ko meaning light or shine is the mark found on the bottom of this bowl. It also has Japan written on the bottom of the porcelain bowl. You could use this bowl not only for rice but also eat your cereal every morning or a snack bowl such as ice cream and popcorn. The scene is of a younger person reading to one of their elders. Colors are red, blue, yellow and green with lots of gold trim. It has some Japanese writing on the back but have no idea what it says. Overall size is 4 ½" in diameter at top with a base diameter of 1 ¾" and it stands 2" tall. There are no cracks or chips. My guess at age would be the 1960's.
