For centuries, Japanese families have turned to kudzu root for its gentle, natural properties. But modern life—processed foods, busy schedules, and daily stress—can make it hard to get the quality our bodies deserve. That's why Ohsawa, a family-run Japanese company founded in 1959, created this specific formula. They source only 100% organic Japanese kudzu root, grown in pristine soil without pesticides, and process it using a traditional, low-temperature method to preserve its natural potency. Every 150g block is certified organic by JAS (Japanese Agricultural Standard) and produced in a GMP-certified facility in Japan, ensuring purity you can trust. It's become a top-ranked thickener and health staple in Japanese households for its reliability and clean results.

Ohsawa Organic Japanese Kudzu Starch Block is a premium gluten-free thickener composed of a single, pure ingredient: 100% organic kudzu starch derived from the root of the kudzu plant (Pueraria lobata). This starch is included as the sole component due to its exceptional thickening properties, which activate when heated in liquids, creating a smooth, translucent gel without altering flavors. The purpose of this ingredient is to provide a natural, plant-based alternative to conventional thickeners like cornstarch or flour, making it suitable for gluten-free, vegan, and allergen-conscious diets. Kudzu starch offers several benefits: it is easily digestible and may support gastrointestinal health due to its prebiotic qualities, it contains trace minerals like calcium and iron, and it imparts a silky texture to sauces, soups, and desserts without lumps. Sourced from organically cultivated kudzu in Japan, this product ensures purity and sustainability, aligning with holistic culinary practices.
