Turning a regulatory shock into a market position 

In 2022, Japan implemented a geographical indication protection policy governing origin claims. The operative requirement was precise: mushroom blocks must be inoculated within Japanese territory for their produce to qualify as Japanese-origin. Our long-standing model — inoculating in China and fruiting in Japan — no longer satisfied the origin test.

Customer volume fell by approximately 60%. Two farms suspended production. Staff attrition followed. Across the sector, the policy eliminated a substantial number of domestic Japanese farms that could not meet the new requirement.

Rather than contesting the policy, we restructured the supply chain around it。

Operating costs doubled. Lead times extended, reflecting both the additional time and the spatial split of the process. The most demanding technical challenge was stabilizing inoculation success rate while controlling contamination rate — achieved gradually over several years of process refinement.

Qihe now holds geographical indication registration protection in Japan — the first foreign brand to do so. Where the policy removed many suppliers from the market, it left us with a defensible position: a registered, recognised local origin status.

• Regulatory capacity — we can reconfigure a supply chain around new market rules, not merely endure them
• IP ownership — strain L3 is developed and registered in-house, with no third-party dependency
• Process discipline — success and contamination rates are managed as core production metrics
• Local substance — real facilities, real staff, real inoculation capacity on Japanese soil
• Demonstrated endurance — a policy-level shock was absorbed and converted into competitive position
