KINJIRUSHI's Quality Checks
Extend to Incoming Raw Materials

1. Inspection of Incoming Raw Materials

Inspectors sample wasabi raw materials sent by producers and check whether they are free from microbial contamination and if there are no issues with color or condition. If any raw material is determined to have quality issues at this stage, we immediately halt the incoming shipment and have a system in place to trace whether other problematic materials have also been delivered.

2. Sanitation and Quality Checks in the Factory

Sanitation inspectors conduct daily patrols to confirm multiple checkpoints, such as whether the factory is kept clean, if manufacturing machines are free of contamination, and whether workers are handling products correctly, ensuring product safety. Additionally, products undergoing manufacturing are inspected in the adjacent quality control room, and if any irregularities are found, staff from the Quality Control Department promptly investigate the cause and resolve the issue.

3. Inspection of Finished Products

Only products that pass inspections at every stage—from raw material arrival to finished product—are shipped. We also test whether product quality is maintained within the stated shelf life and storage conditions, as well as how quality changes if those conditions are exceeded.

Traceability System

In case of any defect, we thoroughly manage all stages—from raw material cultivation information to sub-ingredient and food additive usage, storage, and distribution—so the cause can be quickly identified and addressed. The three domestic factories under KINJIRUSHI Wasabi Co., Ltd. have all acquired FSSC22000 certification under the Global Food Safety Initiative (GFSI).
