Fukumitsuya’s Fermentation Research Lab has been engaged in researching beneficial ingredients and rice fermentation of sake. Carrying on the traditional fermentation technique, the lab harnesses the insights gained from numerous investigations of yeast cultivation into better product development.

Fermentation is old biotechnology whose safety has been proven over a few thousand years. However, we do not yet fully understand the mechanism of this natural process. Its great potential is still largely unexplored.

KOME LAB was born from the lab’s endless pursuit for innovation. We are committed to make available quality beauty and wellbeing products with proven ingredients derived from fermentation. It is our pledge that we will never compromise on the quality.

Innovation creates tradition and generates new innovation. The possibilities are endless. Fukumitsuya as a leader in rice fermentation, will continue to conduct research and development on fermentation-based products.

Our challenge continues.
