At Fujishukin, our mission is to support farmers and rural communities that safeguard both food security and the environment through sustainable mushroom cultivation. We are dedicated to creating an inclusive environment where individuals, including small-scale farmers and people from diverse backgrounds, can easily, enjoyably, and safely engage in mushroom farming.

Through continuous research and development, we have pioneered high-performance spawn, introduced new mushroom varieties, and developed innovative cultivation techniques. These advancements have enabled us to contribute to a secure, sustainable food system and thriving local communities.

By promoting responsible mushroom cultivation, we also support the conservation of forest resources. As we explore the untapped potential of mushrooms, we remain committed to making a meaningful impact, not only locally but globally.

We supply premium-quality mushroom spawn, primarily for log-grown cultivation, to mushroom growers across Japan. Our high-performance spawn ensures stable and efficient cultivation, making it a trusted choice for producers seeking consistent results.

The hardwood trees, such as oak, used for log-grown shiitake cultivation sprout new shoots from their stumps in spring when harvested during the dormant season. By utilizing these logs for mushroom cultivation, we help rejuvenate the forest, keeping the trees young and actively absorbing CO2 as they grow. In 20 years, the trees are ready for harvest again, creating a sustainable cycle that supports the health of our abundant forests.

Log cultivation follows the natural growing process of wild mushrooms found in the mountains. Growing maitake on logs has traditionally been difficult due to its unique nature. However, with our "Maitake Logs," anyone can easily grow log-grown maitake. This innovative method ensures stable and reliable harvests.
