The place Asano Ginger is grown is also home to the pristine clear streams that are distinguished as the Three Greatest Clear Streams of Kochi and consistently ranks at the top of the National Clear Stream Standard Investigation of Japan.

Kochi Prefecture is the largest producer of ginger in Japan, accounting for over 40% of total shipment volume in the country. Among the many Kochi brands, “Asano” grows its ginger at the basin of Shimanto, Monobe and Niyodo rivers, which are First-class rivers and standard bearers in Kochi, resulting in high-quality ginger with clean pungency and outstanding aroma as well as flavor.
In addition, the harvested ginger is processed and stored at adjacent factories without losing its freshness and quality, so it receives the highest praises in Japan’s market as an emblematic first-class ginger of the Ginger Kingdom that is Tosa Province (former name of Kochi Prefecture but still used today by the locals with pride).

Trust for Great Taste
Confidence in Quality and Safety
Trust from our customers is the pride of our production team.

Asano has two production sites. The main factory is located at the Monobe river basin and the other is located on the cape of Shimanto river.
Both factories are located close to our fields where our main product, “Ginger”, is produced, and we established a thorough production system that in addition to providing freshly harvested high-quality ginger at lower cost and faster, we also pay closest attention to line operation, uncompromising hygiene and quality management.
Every one of our 242 employees promote prioritizing the safety of products by standing in our customers’ shoes when engaging in production.

Safe products for people
start from an environment
friendly factory.

At our factories with the most advanced equipment in the industry, we take on bold challenges and give daily effort with a goal of achieving the best ginger processing lines in Japan and the world.

Quality management system
with a goal of zero complaints.

Harvested ginger is stored depending on its category, conventional or special cultivation.
We have integrated an uncompromising traceability system, so we can trace who at which field and how it was harvested. Regarding the process between production to delivery, we have developed a mechanism for quality assurance based on an international standard with strict quality management system. In order to assure safe and reliable products to our customers, we link consistency and high level of safety in our product production, covering farming, storage, processing and delivery.

Throughout R&D, production,
inspection and sales process,
Asano brings together all of
its resources for a thorough
integrated system.

We engage in a daily R&D effort with ginger at the center of focus. Especially regarding research on functionality of ginger, we engage with local universities, regional governments in an industry-academia-government collaboration. Based on the research results, each person involved in the R&D are free to incorporate their ideas and the spirit of challenge into their work by being able to say “I want to create a product like this”, “it would be great if this type of product existed”, etc., and having a flexible system to accept these attitudes as our company policy supports Asano’s unique product development process. Moreover, we conduct sampling inspection (microorganism test) at our research/inspection facility on products that are shipped out on a daily basis. As for the residual pesticide test, we periodically request specialized organizations to implement the testing.
