Discovering the Plant Wisdom and Fermentation Culture of Taiwan’s Indigenous Amis People
Taiwan’s indigenous communities possess a rich knowledge of plants and fermentation that reflects their harmonious coexistence with nature.
On a recent trip, we visited an Amis village, guided by professors and students from Pingtung University of Science, along with a team from Japan’s leading Koji-maker. This journey opened a window into the incredible food culture and plant wisdom of the Amis people, blending ancient traditions with insights from modern science.
A Table Rich with Fermentation
The Amis people’s food culture is a paradise of fermentation. Their dining tables are filled with unique creations like matured pork sushi, pickled fish roe, salted pork offal, and fermented fish eggs. These dishes seamlessly combine the bounty of the sea and the mountains, offering a distinctive culinary experience.
Interestingly, the fermentation of meat and fish was also recorded in Japan’s Engishiki from the Heian period. It described “meat miso” (nikusho) and “fish miso” (gyosho), which have largely disappeared from Japanese cuisine. However, these traditions are still alive in the Amis villages, where wild boar meat is freshly prepared into a fermented paste or cured with salt, creating flavors rooted in sustainability and heritage.
Wild Plants and fermentation
One of the most striking aspects of the Amis culture is their deep understanding of wild plants. According to Wu Xueyue, principal of the Indigenous Vegetable School in Hualien and author of Vegetarian Doctrine, the Amis recognize over 200 types of wild plants, with more than 100 making regular appearances on their tables.
During my visit to the Indigenous Vegetable School, just a short walk from Hualien Station, I was amazed by their thriving garden of wild plants. Visitors can enjoy a guided tour of the garden. This hands-on experience highlighted the sheer diversity of wild plants used in their daily cooking, from herbs with medicinal properties to flavorful greens.
Nourishing Alcohol: Herb-Infused Rice Malt Wine
The Amis also good at creating unique fermented beverages. Their rice malt wine is crafted using 12 different types of plants, each selected for its medicinal benefits, aroma, and preservative properties. Unlike herbal tinctures, where plants are soaked in alcohol, the Amis incorporate these plants directly into the fermentation process, making the plants an integral part of the alcohol itself.
The result is a nourishing, health-boosting wine that combines the benefits of natural fermentation with plant-based medicine. This innovative approach to fermentation reflects the Amis people’s ability to blend practical knowledge with cultural traditions.
Wild Cooking Techniques
The Amis people’s cooking methods are as fascinating as their ingredients. One standout technique involves heating stones until they’re red-hot and then placing them into a bowl of soup made with wild herbs, served in a betel nut leaf bowl. The sizzle of the hot stones creates a fantastic display, releasing aromatic flavors into the soup and adding a wild, earthy touch to the meal.
Their resourcefulness extends to fishing methods as well, using plant-based toxins to stun fish and intricately woven bamboo nets to catch them—a perfect example of sustainable living that respects natural ecosystems.
Bringing Indigenous Knowledge to Japan
Inspired by these experiences, we’re organizing a fermentation camp in Nagano at the end of August. The goal is to recreate Amis-style fermented foods using Japanese wild plants. By understanding why the Amis chose specific plants for fermentation, we hope to adapt these techniques to local ingredients.
In addition, our ethnobotanical food workshops this month will feature recipes inspired by the Amis village. The menu includes:
• Taroko Tribe’s Wild Millet Porridge
• Amis-Style Stir-Fried Matured Pork Sushi
• Stone-Grilled Seafood Hotpot
• Paiwan Tribe’s Pork Millet Dumplings
• Amis Rice Malt Wine (Herb Koji)
• Seaweed Salad with Koregusu and Lime
These dishes will showcase rare fermentation ingredients brought back from Taiwan, along with easy-to-find alternatives for home cooking.

Visit small-scale fermented food manufacturers in Mikawa Aichi prefecture
Fermentation in Mikawa, Aichi prefecture
Aichi is now famous for a major producer of cars, Toyota company, and also steels, but actually, it is also cluster area of food producers. Mikawa, Aichi prefecture is one of the best places to produce koji rice mold. There are many breweries of fermented seasonings such as soy sauce, miso, vinegar sake and mirin. Indeed, Mikawa can be said to be a fermentation district.The reasons why there are so many fermented food manufacturers in Mikawa are:
- good climate
- blessed with nature (mountain, water sources and ocean)
- development of shipping industry in Edo period 17th century
- 5th biggest sake production site
Traditionally, sake was transported and sold in Edo (current Tokyo). Sake residues are recycled to make kasu-zuke (sake lee pickle), vinegar, and amazake (milky sweet sake).
It was really suitable for shipping companies to transport food products from Mikawa to Edo and to Osaka, since it is conveniently located in the middle of Japan in-between Edo(east) and Osaka(west), and compared to Osaka port, the tide flow is stable in Mikawa.

Hacho miso
Hatchō Miso has been made in Okazaki area for a long time since 1645. It's made from just soy bean and salt without using rice or wheat mold, which is very unique to Aichi Prefecture.
Steamed soybeans are mixed with bean koji (fermented soy) and formed into miso balls. The miso ball koji are mixed with salted water and put into a big wooden barrel to be fermented for 2 years.
The unique point of Hacho miso is to use around 500 river stones with a weight of 3 tons are put on top in conical shaped mounds, after sealing the miso ball into the wooden barrels.
There are two company in Okazaki to produce Hacho miso until now, and there is factory tours to learn about this unique miso ball fermentation culture in Aichi.
You can taste Hacho miso in the restaurant. The flavor is very thick and dense, and it goes well with tonkatsu miso and also oden.
Mikawa mirin
The history dates back to 600 years ago. Mirin became popular among especially women, since mirin is sweeter and with less alcohol than sake. It's used for teriyaki sauce (sweet sauce for stewed chicken, yakitori), for boiled fish, and sometimes small amount of mirin can be also used instead of sugar.
I have visited Sumiya Bunjo Shoten and Sugiura Mirin. Both are family-run small-scale mirin producers, which produce

Sugiura Mirin
vinegar
Japanese vinegar, called "su" is made from rice. Can you imagine how rice will be vinegar? In Mikawa, there is a great vinegar museum, where you can learn the activities of microbes, which convert sugar into alcohol, and alcohol into vinegar.Mitsukan, a large scale vinegar manufacturer was once a sake brewery.
Miyamoto koji mold producer

Koji (fermentation starters, comprising aspergillus or other microorganisms cultured on the surface of soybeans, rice, or barley grains) plays an essential role in the fermentation process.
Miyamoto koji ten produces multiple types of koji all year around (rice koji, mugi wheat koji, bean koji). It also produces miso during winter season from December to March.
Fermentation learning
Aichi is the perfect place to learn about fermentation culture and Japanese seasonings. There are many family-run traditional producers of miso, tamari shoyu, mirin, sake and vinegar, which keep their traditional way of brewing.Please visit Aichi and learn Japanese knowledge of fermentation.

Walking the Sreets of Fushimi Sake Town
When you hear the name Fushimi town in Kyoto, what comes to mind? To mention a few, it is a town well known for the thousands of vermillion “Torii” of Fushimi Inari Shrine, a destination for Japanese saké connoisseurs and lovers, and noted for its street names taken after famous warlords in Japanese history. For centuries, locals and visitors alike would gather during the New Year holidays at Fushimi Inari Shrine to pray for peace and prosperity.
Mornings begin early in Fushimi. Even before sunrise, white smoke can be seen rising from saké breweries. That's when we know that saké production is in progress and as the aroma fills the air. For the residents of Fushimi , "Saké" is a part of life as well as livelihood. Many of the parents whom we befriended during our children's kindergarten and primary school years worked for saké companies. Every early winter these parents would share “Saké Kasu” 酒粕 (lees from saké production) made by the different nearby breweries. At a glance, “Saké Kasu” may look similar. The truth is each has its own unique flavor crafted by the brewery that produces it.
In Fushimi, we live in the mixture of touristy and local life. There are shops focusing on tourists but there are many family owned shops specializing in all kinds of things where the locals frequent. To name a few, we have shops for fish, eel, pickled vegetable, lantern, traditional betrothal gift, tatami mat, traditional sweets and tea.

Fermentation experience at a farmer's kitchen and soy sauce brewery in the Yamanobe ancient trail
Nature’s Way - When it comes to food
The Yamanobe Trail which runs through the countryside of Nara, is thought to be one of the oldest roads in Japan. Part of this road winds its way through the eastern edge of the Nara Basin, an area dotted with kofun - ancient burial places of Japanese royalty. Among these is said to be the final resting place of Queen Himiko, who ruled these lands more than a thousand years ago.
Soy sauce brewery Daimon Shoyu
Daimon Soy Sauce Brewery has been passed down through the women in Maki’s family, along with a passion for natural brewing methods. While much modern soy sauce is made in sterile factories, and has many additives to keep the flavor stable for a long period at room temperature, Daimon Soy Sauce is made using traditional techniques in enormous wooden barrels using koji bacteria that is cultivated in-house. As a daughter and mother, Maki is proud to use high quality ingredients and traditional techniques to produce a safe and healthy products for her family and people everywhere.
As soon as we entered the brewery we were hit by an earthy salt caramel-like smell. The entire space was a soy sauce ecosystem - life was in the air.
Organic Farmer's Kitchen "Himiko's Garden"
After Daimon Soy Sauce, we took a short trip to Himiko’s Garden, a community kitchen and cafe, where we met Kaori - an organic farmer who grows ancient varieties of rice using natural farming methods.Originally from Osaka, Kaori was inspired to move to Nara and study natural farming under an expert as she was concerned about the amount of additives and sugar in modern food. When she started growing her own fields of rice, she out-produced all her neighbours and even her teacher came to find out how she did it. After the tasting Kaori also took us down to the fields to look at the rice. In spite of the recent storms, the plants were looking healthy. She showed us the ancient black and red varieties as well as rice famous in sake-making.
When the rice was ready we sat down to a delicious macrobiotic lunch of vegetables, tofu, chicken, rice and miso soup. The food certainly packed a more nutritious punch that your average meal. After lunch we were brimming with energy.

How to make shoyu (soy sauce) at home
Please see the link below more about the production of soy sauce in Japan.
"Hishio no sato" a home of soy sauce, Shodo shima island
How to make soy sauce
They key to make shoyu (soy sauce) successfully is depending on koji malt (fermented soy beans and wheats).Ingredients
wheat : soy bean = 1:1water : soy bean = 1.1 : 1
salt 18% of total amount
To make sweeter shoyu (called usukuchi), increase the ratio of wheat more than soy, then, the taste and the color will be lighter. If you reduce wheat, the taste will be thicker and color will be darker (called koikuchi).
2. boil or steam halfway till the beans get soften
3. roast wheats
4. mill wheat after roasted
5. mix crushed wheat with tane koji (starter) and boiled soy beans
6. put in muro (temperature controlled room) for 3 days with the room temperature 36-38 Celsius degree.
After filtered soy sauce, the leftover also can be used for making "jiang" mixed with chili powder and rice koji.
