About Shogun Maitake

Company History

Maitake From Japan to the World

Maitake Mushrooms are rare and hard to find in nature. They are highly prized and are an incredible food and source of protein. As an environmentalist and humanitarian, Shogun’s founder, CEO & President Yoshinobu Odaira founded Yukiguni in 1983 to grow and develop new proteins for the Japanese market. At the time, Black Maitake mushrooms were rare and only available in the wild.

These were a prized delicacy at a cost of $250/kg. Mr. Odaira set out to lower the cost of production and produce large volumes of Maitake mushrooms with quality that exceeded the most prized wild mushrooms. It took 6 years and many failures to grow large organic maitake mushrooms consistently. Mr. Odaira’s company grew to a production footprint of 420,000 sq. meters (4.2 million sq.ft.) and delivered 70% of the Japanese market.

In his next phase of expansion Mr. Odaira sought to globalize and produce Maitake to share with the rest of the world. In 2015 Mr. Odaira founded Shogun Maitake Canada Co., Ltd. in London Ontario, Canada.

The initial footprint consisted of 12,000 sq. ft. prototype facility to test, develop and prove production was viable in Canada. The product now exceeds the best quality in Japan, the production is at full capacity, with batches cultivated each and every day, Shogun can deliver fresh Maitake into the eastern Canada and the north-eastern USA continuously.

Plans are in place to complete phase 1 of new facility 136,000 sq ft in 2022, in Municipality of Thames Centre. Shogun’s team brings a strong knowledge of the Maitake production, the business and markets. Under Mr. Odaira’s leadership Shogun Maitake Canada Co., Ltd. offers many unique opportunities.

Our goal is to fulfill the corporate social responsibility through innovations.  Our new mushroom production facility aims to achieve net-zero carbon emissions within 5 years by adopting the clean energy technology.  We have many other projects in the works to improve the sustainability and the energy efficiency and we are committed to becoming Net Zero for our customers and industry. We are here to lead the way for sustainable commercial farming practices.

History of Maitake Production

High Efficiency

Founder Yoshinobu Odaira succeeded in the steady production of maitake mushrooms, known to be difficult to cultivate, in Japan, where he set up a one million square foot growing facility. On top of this, he conducted two years of precise cultivation research in Canada. We now know that maitake products can be produced in Canada which are higher in quality than even those produced in Japan.

Mr. Odaira worked on developing new techniques for many years. The result is our very high production efficiency rate.

Superior Quality

The most difficult aspect of maitake cultivation is maintaining consistency in production quality. Many maitake producers have folded due to its complexity to make a consistent product. Yoshinobu Odaira with more than 35 years of experience in successful maitake cultivation have spent the last three years in Canada, researching and developing the most optimal growing strategies for the region. Their efforts have made it possible for Shogun Maitake to produce the perfect products for North American needs.

What separates Shogun Maitake Canada from other producers is its unrelenting prioritization of quality. Shogun Maitake cultivates maitake mushrooms longer, resulting in flavors which are closer to those found in nature. We are the first company to sell black maitake in Japan and North America. (Known for its top ranking within maitake species, black maitake is very rare even in natural environments.)
