Hoshino Natural Bread Starter is a traditional Japanese bread starter made using brewing-inspired fermentation methods with naturally collected yeast, Japanese wheat, rice, koji, and water.
Founded in 1951, Hoshino describes this as one of its long-trusted signature products, valued for bread with a moist, chewy texture and a deep, fragrant flavour. It can be used across a wide range of breads, including sandwich loaves, sweet buns, French-style breads, and pastries, and it is especially appealing for bakers who enjoy taking more time to build flavour.
For bakers exploring shokupan, café-style buns, or naturally expressive homemade bread, it offers a distinctly Japanese fermentation character rooted in rice and koji culture.

Good to know
This is not an instant yeast. Before baking, you first prepare a live starter by mixing the bread starter into warm water at about 30°C, then letting it ferment at about 28°C for 24 hours. Once ready, the starter should be refrigerated, stirred before use, and used within about 1 week. Hoshino notes that this extra step is part of what helps create the characteristic aroma, texture, and depth of flavour.
Why bakers choose it
Hoshino is a great option for bakers looking for a more traditional Japanese approach to bread fermentation. Its rice-and-koji base gives it a distinctive identity, while the slower starter process makes it especially attractive to those who enjoy breadmaking as a craft rather than simply the fastest route to a finished loaf.
Storage
Store airtight in the refrigerator. After preparing the live starter, keep it refrigerated and use within 1 week.
