Maitake is a very large mushroom, which grows deep in the mountains of northeastern Japan, as well as in North America and Europe. Famous for its taste and health benefits, maitake is also known as the "dancing mushroom: 1 Legend holds that those who found the rare mushroom began dancing with joy. Others attribute its name to the way the fruit bodies of the mushroom overlap each other, giving the appearance of dancing butterflies.

Maitake is extremely sensitive to environmental changes, which have presented many challenges to those cultivating this mushroom. However, Japanese farmers have succeeded in producing high-quality organic maitake mushrooms, allowing for wider availability both in Japan and the U. S. The fruiting body and mycelium of maitake are used medicinally.
