Joshinko, also known as non-glutinous rice flour, is a staple ingredient in Japanese cooking that has been used for centuries to make traditional sweets and savory dishes. Unlike glutinous rice flour, which creates a sticky and chewy texture, joshinko is made from regular short-grain rice and results in a smoother, lighter, and less elastic consistency. Its versatility makes it popular for making rice cakes, dumplings, and various wagashi (Japanese confections). For anyone interested in Japanese cuisine or gluten-free alternatives, learning about joshinko is both useful and fascinating.
What is Joshinko?
Joshinko is a finely milled flour derived from polished non-glutinous rice, also called uruchimai in Japanese. This type of rice is the same kind commonly eaten as steamed rice in Japan. The flour is white in color, smooth in texture, and has a subtle flavor that blends well with sweet or savory ingredients. Unlike mochiko, which is made from glutinous rice, joshinko does not become chewy when cooked. Instead, it produces a firmer bite, which is ideal for specific recipes.
How Joshinko is Made
The process of making joshinko involves washing and soaking the rice before grinding it into a fine flour. The flour is then dried and packaged for cooking. This method ensures that the flour retains its natural properties without the stickiness associated with glutinous rice. Because of its neutral taste, joshinko works well in both traditional and modern recipes.
Difference Between Joshinko and Mochiko
It is important to distinguish between joshinko and mochiko, as both are rice flours but behave differently in recipes. Mochiko is made from glutinous rice and creates chewy, stretchy textures like those found in mochi. Joshinko, on the other hand, results in a firmer, less elastic texture.
- JoshinkoMade from non-glutinous rice, creates smooth and firm textures, commonly used in manju and dango.
- MochikoMade from glutinous rice, creates sticky and chewy textures, often used in mochi and daifuku.
Choosing the right type of rice flour is essential to achieve the intended result in Japanese cooking. Substituting one for the other may completely change the texture of the dish.
Traditional Uses of Joshinko
Joshinko has a rich history in Japanese cuisine. Some of the most popular uses include
- DangoSmall rice dumplings often served on skewers and flavored with sweet soy sauce or covered with anko (red bean paste).
- Kashiwa MochiRice cakes wrapped in oak leaves, traditionally eaten during Children’s Day celebrations.
- ManjuSteamed buns filled with sweet red bean paste, where joshinko provides a smooth outer dough.

These foods highlight the versatility of non-glutinous rice flour in both sweet and savory contexts. Its ability to hold shape makes it perfect for molded confections and dumplings.
Modern Adaptations
Beyond traditional recipes, joshinko is now being used in contemporary cooking. Bakers often experiment by mixing it with wheat flour for unique bread textures, while home cooks use it as a gluten-free thickener for soups and sauces. Its adaptability makes it a valuable ingredient in kitchens worldwide.
Cooking with Joshinko
Working with joshinko is relatively simple, but it requires some technique to achieve the best results. Typically, joshinko is mixed with water to form a dough, which is then shaped and steamed or boiled. The resulting product has a firm yet tender bite. Because it lacks the stickiness of glutinous rice flour, the dough is easier to handle, making it a great starting point for beginners exploring Japanese sweets.

Joshinko in Global Kitchens
Although it originates from Japan, joshinko has gained popularity in international cooking. Chefs and home cooks around the world experiment with it in pastries, dumplings, and even fusion dishes. Its neutral taste allows it to pair well with both Asian and Western flavors, making it a valuable ingredient for creative recipes.
Common Substitutes
If joshinko is not available, alternatives like rice flour from other regions can sometimes be used. However, the texture may differ slightly. Glutinous rice flour is not a suitable substitute due to its sticky nature, but regular rice flour from Asian grocery stores may provide a similar result.
Tips for Buying and Storing Joshinko
Joshinko is often available at Japanese grocery stores, Asian supermarkets, or specialty food shops. When buying, look for finely milled, white rice flour specifically labeled as non-glutinous. To preserve its freshness, store joshinko in an airtight container in a cool, dry place. It can also be kept in the refrigerator or freezer for longer shelf life, especially in humid climates.
