Step into a world of tradition and flavour at a soya sauce and miso brewery founded in 1911. Located in Oonomachi, Kanazawa—a historic port town known since the Edo period as one of Japan’s top five soya sauce-producing regions—Yamato Soya Sauce & Miso has been crafting fermented foods for over a century.

To share the wonders of koji (the magical fermentation starter) and the beauty of fermentation culture, Yamato established Koji Park, an interactive facility offering hands-on tours and tastings for visitors from Japan and abroad.

Wander through time as you explore the historic landmarks such as the charming red brick boiler, iconic chimney that seems to carry the scent of roasted wheat on the breeze, and traditional wooden storehouses that have been adapted to production spaces and shops—all set against the scenic backdrop of Kanazawa Port and the distant Hakusan and Tateyama mountain ranges. It’s the perfect blend of history and photogenic charm—just 15 minutes by car from Kanazawa Station.
Before or after the activity, enjoy shopping at the on-site product showroom, indulge in a cheesecake treat, or explore doburoku (cloudy sake) brewery.

Included in the activity are:
*Learn about the magic of Koji (12:00-12:30)
An entertaining and informative introduction to fermentation and the magic of koji. You will learn: 1. What’s koji, 2. The Secret of Fermentation, and 3. How to promote intestinal health.

*Koji Park Tour & Miso Soup Making & Doburoku Tasting (12:30-13:15)
A guided tour of the facility (Outside tour may not be available depending on weather conditions, in which case we will issue a full refund to the guest). Make your own miso soup using simple recipes and two types of miso pastes aged from 6 to 12 months—compare the flavours and discover your favourite. Taste two types of doburoku, a fermented rice drink packed with koji, yeast, and lactic acid bacteria—a true superfood.
