3 Koji-Based Food Experiences in Yamaga – From Miso Soup to Miso Caramel
We head to the Kamoto area of Yamaga to introduce three must-try stops for miso, soy sauce, and koji-based treats—yes, even miso caramel desserts!

Hi there! I’m Tabeena, your active, food-loving local explorer 🐝
This time, we’re off to Yamaga’s Kamoto region—a historic rice-growing area full of flavor and tradition.
We’ll visit three unique spots specializing in miso, soy sauce, and kōji (the fermentation starter essential to Japanese cuisine). These places combine centuries of tradition with modern flair—and one of them even serves sweet miso caramel desserts!
Let’s gooo! 📷
Himiko Shoin (卑弥呼醤院)




Himiko Shōin’s signature miso is known for its rich depth of flavor—thanks to the careful cultivation of kōji, a technique refined since the late Edo period when the business started as a sake brewery.
This time-intensive fermentation process is passed down through generations and still done by hand today. The result? Miso and soy sauce with a deep yet gentle umami taste.
Inside, the Sakura-Sakura Café offers 16 varieties of miso soup—all made without additives, letting the natural flavors shine.

Marukame Hakko Cafe (発酵café マルカメ)




Operating since 1870, this long-running soy sauce and miso maker launched a stylish café in 2019, blending tradition with innovation.

Kiya prides itself on using local ingredients and aims to bring the joys of fermented food to modern lifestyles without sacrificing authenticity.
