FAQ

"Learn all about the process of making miso, the fermented soybean paste that acts as a cornerstone of Japanese cuisine. "

Walk through the beautiful city of Matsumoto, famous for its original castle that towers over the downtown area. Among the old buildings of the city is a miso factory that’s been in operation since 1868. Tour through the miso factory that includes miso in every stage of the fermentation process. Soybeans, koji and salt are mixed and aged in cedar barrels. The miso here ages for three years, so you can see the difference between the newly made and aged miso. Your guide will explain the process of fermentation, and how the factory creates smooth and creamy high-quality miso. After the tour, enjoy a meal featuring the miso from the factory! Dishes featuring the different miso the factory produces highlight and complement the quality of the local ingredients. Of course, no miso meal would be complete without miso soup! This healthy dose of fermented soybeans is not only delicious, but also packed with amino acids that are good for your health.

Tour was quick and informative. The lunch afterwards was delicious and very filling, and the dining are was very peaceful with a beautiful view of a garden. We also got T-shirt's, an apron, and a jar of the 3 year miso. Would definitely recommend to experience!

I really enjoyed this experience. The tour itself was fairly short, but it was comprehensive. The lunch was delicious.

Brian FeltovichDecember 2025 • byFood

The tour is free if you come to the factory on your own but we enjoyed hearing about the process of making miso from the 6th generation of the founding family. Lunch was delicious and we received t-shirts and jars of miso as gifts. Maybe not worth the price but we had fun anyway.

There was some misunderstanding with tour guide, who didn't show up, but we got tour from person who runs the miso plant and had incredible lunch
