Over 20 tons per year: the largestscale harvest in Shikoku
1, The most delicious, high quality water in Japan

Wood ear mushrooms are more than 80% water. We believe the flavor, quality, and mouthfeel of our mushrooms is determined by the quality of the water they’re grown with. We’re committed to the water we use, and feed our mushrooms the same water
that we ourselves drink on the plantation. That’s what allows us to stand behind our product. From cultivation to the washing phase, we only use natural spring water from the Niyodo river.

2,No pesticides, no preservatives

Many imported brands spray their crops with chemicals and insecticides, but did you know that a lot of places in Japan use these imported wood ear mushrooms in their school lunches?
Also known as “edible Chinese medicine,” wood ear mushrooms have been shown to help with digestion and vitamin absorption. That’s why our company is committed to never use pesticides, so that adults and children alike can receive the nutritional benefits of wood ear mushrooms safely and without worry.

3,We inspect and pack every single mushroom by hand

We ship our product to restaurants, culinary institutions, and supermarkets all across the country, operating by hand from quality control to final inspection. Being the same variety of mushroom, our product may appear the same as our competitors, but once rehydrated, you can see the difference in quality, condition, and usability.

4,The perfect environment: natural mist and temperature differences make for happy wood ears!

Natural mist that welcomes the dawn and dusk kisses our wood ear mushrooms with moisture. Especially in the summertime, we’ll often open up the sides of our greenhouses to let more of that natural mist in. The mushrooms soak it up, stimulating their growth and leaving their surfaces damp and moist. Where our plantation sits 750 meters above sea level in the Shikoku Mountains, the days are hot and the nights are cold. This temperature difference is optimal for the growth cycle of the wood ear, resulting in a tender and meaty mushroom.

After cutting off their hard stems (the root), raw wood ears are washed and then sun-dried for 2-3 days. The sun-drying boosts vitamin D levels. It may also be beneficial to let dried wood ears sit in the sun at home for 5 or 10 minutes before using.
