Why Silkworms

Sericulture, which originated over 5,000 years ago in China and later became a cornerstone of modern Japan’s economic development, now faces the threat of extinction. In partnership with Shinshu University, we have uncovered the potential of the silkworm as a high-value protein source. Because silkworms are raised solely on mulberry leaves, the resulting powder not only resembles matcha in color and aroma, but also offers various benefit for our health. This unique ingredient can be enjoyed as-is or used across a wide variety of food applications, making it a truly versatile innovation for the future.

100% Natural, Traceable, Made-in-Japan
