What Is Joshinko?
Joshinko is a white rice flour (high quality powder of non-glutinous rice) made from ordinary rice (non-glutinous rice).
It’s made by drying polished rice and milling them. Mainly, joshinko is used as a confectionery material.
There are different types of white rice flour depending on the roughness of flour.
・Coarse one … Shinko or Nami-shinko
・Fine-grained one … Joshinko
・More fine-grained one … Joyoko
Out of these, I would say joshinko is the most common white rice flour especially when we speak of making Japanese sweets.
When making noodles and bread using rice flour, by the way, you will need special rice flour for it which often contains gluten.
For your information, the same method, made from glutinous rice is called mochiko.
How Is Joshinko Used?
Dango (Dumpling Ball)
Dango made with joshinko has a little harder texture than the one made with mochiko and shiratamako. There is less sticky feeling because it’s not made from glutinous rice but ordinary rice (non-glutinous rice).
This is a flat and rounded joshinko rice cake with sweet bean paste inside. The rice cake is wrapped in oak leaf which is called “kashiwa” in Japanese.
As for the leaves of oak, old leaves do not fall until the shoots grow. That is why kashiwa-mochi is eaten (offered to the god) on Children’s Day, May 5th as a symbol of prosperity of descendants.
It’s a Japanese traditional sweets, sweet rice jelly made by kneading rice flour with sugar and hot water, then pouring into a mold and steaming.

Some are made from ordinary rice (non-glutinous-rice), others are made from glutinous rice. Some powders are made by mixing these.
