It’s no secret that Japan loves fermented food. From miso soup to umeboshi, fermentation is a daily staple in Japanese cuisine. Every Japanese supermarket is stocked with a variety of gut-healing products.

If you’re not quite ready to stock up on natto, worry not, because there are lots of other ways to get the benefits of fermentation, including through dessert. So, what are the benefits of fermentation, where is it found in Japan and how can you enjoy the perks of fermented food through dessert?

What Are the Benefits of Fermentation?

A lot of bacteria in your body may not sound appealing, but when it comes to good bacteria, you need it to support your bodily functions. Fermented food can help stimulate good bacteria and promote better health. It aids digestion, helps you absorb nutrients and vitamins, improves mood and behavior, supports heart health and protects you from inflammation.

With all these benefits, who wouldn’t want to get on the fermented food train?

What is the Japanese Fermented Cuisine?

Although fermentation is a worldwide culinary phenomenon — products like yoghurt, beer, and cheese — fermented ingredients form the very base of Japanese cuisine. The fermentation process involved in making soy sauce, miso, mirin and sake is rooted in Japanese cultural heritage. Even though fermented food is not exclusive to Japan, according to health scientists, the abundance of fermented products might actually be part of the reason why Japanese people live as long as they do.

There are various forms of fermentation in Japan. The most commonly consumed is a microbe called koji, used in the production of nihonshu, shochu, miso, soy sauce and tsukemono pickles.

Besides food and beverages, fermentation is used in other areas of life, including the beauty industry. The famous skincare brand SK-II produced an essence with Pitera, a sake-brewing yeast ingredient that rejuvenates the skin.

When it comes to desserts, a mug of hot steaming amazake is a traditional Japanese winter drink. Its gastronomic history goes back 1,300 years, when it was a beverage for the upper classes. Various famous brands such as Lotte have also started incorporating fermented ingredients such as fermented butter into their sweets.

But there are some that take it even further. We’ve made a list of various shops in Tokyo where you can get more of your favorite desserts. The best thing is that they also happen to be healthy. From wagashi, traditional Japanese confectionary, to more Western delights such as donuts or cheesecake, fermentation is the new superfood for sweets.
