Japanese Yams: how this forgotten vegatable is getting more popular

What are Japanese Yams and How Did They Come To Be?

Japanese yams are some of the most popular vegetables in Japan. They are used in a variety of dishes, from simple boiled or steamed yams to more complex dishes such as tempura and sushi rolls. What is the history of Japanese yams? And how did they become so popular?

The origins of Japanese yams are unknown, but they may have originated in China or Southeast Asia. The first recorded mention of them was in a book written in 1597 by the Dutch explorer Joris van Spilbergen. He called them ‘yams de Oost Indische eiland,’ which means ‘yams from the East Indian islands.’ Over time, the name became ‘Japanese yams.’

Japanese yams are grown throughout Japan, but they are especially popular in the southern area around Fukuoka and Kagoshima. There is also a small community of Japanese yam growers in Oregon.

What makes Japanese yams so special?

Japanese yams have a sweet taste and a firm texture. They are also high in carbohydrates, which makes them a good source of energy. It’s used in sweets, desserts and some Japanese cuisines. Japanese yams are typically served boiled and sliced. They can also be stir-fried or roasted and eaten as a porridge or soup. You can use them in many other ways: dumplings, pickles, cakes and breads. Japanese yams are usually eaten with tea or sake.

Raw Japanese yams are not easy to come by in Japan. Most of the time they’re sold frozen or canned.

History of Japanese Yam

The yam (Dioscorea rotundifolia) is a member of the nightshade family that grows in temperate and subtropical regions around the world. The fruit of the yam is a staple food in East and Southeast Asia, where it is known as sweet potato or tapioca. In Japan, it is most commonly known as oshinko. There are many varieties of oshinko, but the most popular is the white oshinko (Dioscorea alata).

Types of Japanese Yam

There are three types of Japanese yams: daikon, taro, and sweet potato. Daikon is the most popular, followed by taro, then sweet potato. Each type has its own unique flavor and texture. Here are a few tips to help you choose the right Yam for your dish.

Daikon Yam:

Daikon yams are the starchiest of the three yams. They can be used in soups or as a main ingredient in stir fries or other dishes. They have a slightly sour taste and a firm, crunchy texture.

Taro Yam:

Taro yams are slightly sweeter than daikon yams and have a softer texture. They’re often used in savory dishes like stews or dumplings. They have a mild flavor and can be cooked either boiled or roasted.

Oshinko Yam:

Oshinko yams are an ancient variety of yam that have been cultivated in Japan for over 5,000 years. They’re sometimes called the Jewish potato because they resemble the shape of a potato. They have a slightly sweet flavor and are often used to make dumplings or stews.

You can also find Japanese yams at specialty Japanese grocery stores in some cities or even supermarkets that sell imported goods. If you see them at a supermarket, they will be labeled as ‘Kyoto Yam’.

Other Benefits of Japanese Yams

If you love Japanese yams, there are plenty of other benefits to enjoying them besides their delicious taste. Here are five of the most popular reasons why people love eating yams:

1. They Are a Good Source of Dietary Fiber

One cup of cooked Japanese yams provides about seven grams of fiber, which is more than half the recommended daily intake for adults. This helps regulate blood sugar levels and keep digestion running smoothly. Plus, fiber is an essential part of a healthy diet because it helps reduce the risk of obesity and heart disease.

2. They Are a Good Source of Manganese and Copper

Yams also contain trace amounts of manganese and copper, which are both essential minerals for human health. Manganese helps to produce energy while copper assists in protecting cells from oxidative damage. Both nutrients are important for maintaining good nerve function and preventing chronic diseases such as Alzheimer’s and Parkinson’s.

Unlike many other types of food, yams don’t contain a lot of calories or fat. This makes them a great option for people who want to lose weight or manage their calorie intake in a healthy way
