On behalf of the Japan Oil Chemists’ Society (JOCS), I am delighted to welcome researchers and professionals from around the world to WCOS 2027, the 3rd World Congress on Oleo Science, taking place in Hakodate, Hokkaido, Japan, in September 2027. 

This congress holds special significance as it marks the 75th anniversary of JOCS, an institution dedicated to advancing oleo science and fostering global collaboration.

Hokkaido’s breathtaking summer landscapes and refreshing climate provide an inspiring backdrop for this gathering, while Hakodate—an enchanting blend of history, culture, and natural beauty—sets the stage for vibrant scientific exchange and collaboration.

WCOS 2027 brings together leading experts in oleo science, an interdisciplinary field encompassing Oils, Fats, and Lipids Science, Biotechnology, Oleo Materials and Nanotechnologies, and Colloid and Interface Science. This congress provides a unique platform for researchers to collaborate across these disciplines, fostering innovative solutions and shaping the future of oleo science.

We warmly invite you to join us in Hakodate, Japan, for this exciting global congress, where new knowledge will be shared, valuable connections will be made, and innovative ideas will take shape. Let’s advance oleo science together!

Convenient Access & Stay Connected!

The congress venue is just 20 minutes by bus from Hakodate Airport, with direct flights available from Tokyo, Osaka, and Nagoya. Alternatively, you can enjoy a scenic bullet train journey from Tokyo, experiencing Japan’s natural beauty along the way. Our official website will be continuously updated—bookmark this page to stay informed about the latest conference details.

Oleo science is a dynamic field dedicated to understanding the functions and properties of oils, fats, and lipids from plants, animals, and microorganisms. Research in this area drives innovations that enhance health, sustainability, and industrial applications. For decades, JOCS has been at the forefront of oleo science, fostering breakthroughs in edible oils and fats, cosmetics, soaps, and detergents.
