Yukiguni Maitake

Yukiguni Maitake

With our unique technology, in 1983 we succeeded in mass-producing maitake—so rare an item that in Japan it has been known as “the phantom mushroom.” Our mushrooms are farmed in a facility, so you can even enjoy them without washing.

Make your everyday foods even healthier
by applying a little “Maitashi”!

What does “Maitashi” mean?

“Maitashi” means “adding maitake.” Adding some maitake to your everyday dishes makes for a delicious and healthy way of life.

Why “Maitashi” Is Delicious

Guanylic acid, the umami ingredient characteristic of mushrooms

Most varieties of edible mushroom contain guanylic acid. This is an ingredient that draws out the umami in a food. If you add Yukiguni Maitake to your everyday food, it will deepen the tastes and make your dishes all the more flavorful.
※Umami is one of the five basic tastes (together with sweetness, sourness, bitterness, and saltiness).

Protease, for softening meat

The protease (proteolytic enzymes) contained in maitake serve to break down the protein in meat, causing an increase in the amino acids and such that are components of umami. As the meat softens, the umami components at the same time spread throughout the food making the dish all the more delicious!

Their crispy texture delivers both a pleasing mouth feel and a sense of fullness!

Compared to other mushrooms, Yukiguni Maitake is low in water content. Even if you cook them, they still deliver a crispy texture and add a feeling of volume to your dish. They are pleasing to chew, which keeps you from eating too quickly or too much.

Why "Maitashi" is Healthy

A treasure house of dietary fiber that will please your stomach!

Dietary fibers are said to do the job of keeping the environment inside your intestines in good shape. The abundance of such fibers in maitake can be expected to have positive dietary effects such as relieving constipation and keeping the amount of fat and sugar your body absorbs in check.

Loaded with alpha (α) and beta (β) glucans that improve immune strength!

Present in maitake in great quantities, alpha- and beta-glucans are functional ingredients whose capacity for improving someone’s immune strength is thought to have such benefits as helping someone to recover from influenza and have cancer-fighting effects.

Keep blood sugar down after you eat!

The dietary fiber found in abundance in maitake is thought to also help with keeping blood sugars from rising after you eat. Furthermore, you can also anticipate a “second meal effect” from maitake as having the mushroom as part of your first meal will also help keep your blood sugar from rising after the next meal you eat, too.

Filled with vitamin D that strengthens your bones and helps you to live a long and healthy life!

In Japan, having healthy bones is said to be important for living a long life. Combining foods that are rich in calcium such as fish, meats, and cheese with maitake that is rich in vitamin D promotes your body’s absorption of calcium. It will make your bones strong and help you to live a long and healthy life.

Safety Initiatives

Maitake Farming Factories

Our Yukiguni Maitake farming factories are located among the mountains in Minamiuonuma City, Niigata Prefecture, Japan, where water is plentiful and the air is clean. Yukiguni Maitake mushrooms are produced using biotechnology that we ourselves have developed and raised in an indoors environment that recreates the optimal growing conditions. Our mushrooms are farmed in a facility, so the product we can supply throughout the year will always have same, stable high quality and a delicious flavor that never changes.

Safe and Secure Products

We inspect the basic ingredients and water we use for heavy metals and microbes, and use no chemicals or pesticides. We engage in strict quality control and inspections of our products. We have also created and maintain a food safety management system that is based on the ISO22000 standard, and produce products that are safe and secure.

Producing Our Maitake

We believe the flavor, mouth feel, quality, and freshness of our maitake to be crucial. Accordingly, we take about three months to cultivate large roots that are close to the kinds of maitake that grow in the wild. These are large roots on the order of 800 grams, so you can look forward to enjoying thick stems and large, fleshy caps.
