A covered Japanese dish from my Aunt Rose

Any information about my little "melon covered sugar" dish would be appreciated! It has a little slot on the handle end that a spoon handle would fit through.

It is a precious gift from my old aunt Rose who does not remember where or when she received it. Just "a long time ago".

Was it originally part of a larger collection of items such as it is or ??

Thank you,
