美味しいお酒日本酒?焼酎)を造るために重要な原料のお米について着目しています。イネの栽培时の気象条件がお酒の製造工程に及ぼす影响やお酒の品质に影响を及ぼす原料成分を研究しています。

Our research focus is the understanding of the properties of the ingredient rice grains and water for sake making to make high quality of sake and shochu. We are investigating the influences of meteorological conditions during rice growing on sake making process, and the compounds affecting sake quality.

醸造に関わる微生物(酵母麹菌)の机能解明、育种、醸造环境で働く酵素の研究をしています。また、微生物由来の酵素の机能を明らかとし、新しい利用方法や大量生产する技术についても研究しています。

I am studying microbiology(yeast and koji-mold)for brewing. In particular, the main targets are elucidation of functions, breeding, and enzymatic research. I am also interested in exploring new enzymes, developing new uses, and mass-producing enzymes.
