Sake is a useful tool for promoting local industry, but sake consumption has been decreasing year by year. In Gunma prefecture, the Gunma industrial technology center has playing a central role in breeding original sake yeast. Furthermore, for quickly corresponding with the needs from market, JAEA have tried breeding of sake yeast by ion beam breeding technology for development of distinctive sake yeast and its practical use while closely coordinating with the Gunma industrial technology center. As a result, the high ethyl caproate producing novel sake yeast were obtained.
