OEM バイヤー向け FAQ
Q. Why are lead times for authentic Wasabia japonica powder typically 6–12 weeks?
Authentic wasabi cultivation involves a multi-year cycle in water-managed beds, and the rhizome is harvested only when mature. Drying and milling adds further processing time. For powder lots of 1–10 kg and bulk paste at 100 kg+ scale, suppliers typically quote 6–12 weeks from order confirmation. Larger or off-spec lots may extend further into the next harvest cycle.

Q. How should buyers verify that a 'wasabi' powder is genuine hon-wasabi?
Request a certificate of analysis specifying the botanical source (Eutrema japonicum / Wasabia japonica) and the proportion of hon-wasabi in any blend. Reputable Japanese suppliers will issue documentation declaring the hon-wasabi percentage and any added horseradish, food coloring, or stabilizers. For US import, FDA labeling guidance requires honest distinction between 'wasabi' and 'wasabi-flavored' (horseradish-based) products on finished consumer packaging.

Q. What documentation is needed for export to the EU and US?
EU import requires general food import documentation, allergen and ingredient labeling per EU Food Information to Consumers regulation, and contaminant testing where applicable. US import is GRAS for wasabi as a spice and proceeds under standard FDA food import procedures, with allergen labeling for any added ingredients. Buyers should specify the destination market at RFQ so the supplier issues format-appropriate COA and origin certificates.
活用事例
Stabilized wasabi tube paste
- ポジショニング
- Foodservice and retail format — stabilized paste manufactured from rehydrated wasabi powder (often blended with horseradish), with the hon-wasabi percentage declared on the label per Japanese industry guidance.
- 配合上の注意
- Powder is typically rehydrated, blended with binders and stabilizers (xanthan gum, sorbitol), and packaged in oxygen-barrier tubes. Pungency must be developed before paste filling; once stabilized, it is more shelf-stable than fresh-grated rhizome but loses peak aroma over months.
Snack seasoning (wasabi peas, rice crackers, peanuts)
- ポジショニング
- Convenience snack format — wasabi powder is the base for the spray-dried or dusted seasoning applied to coated nuts, peas, and senbei rice crackers in both domestic Japanese and export markets.
Sushi/sashimi accompaniment supply (foodservice)
- ポジショニング
- Premium Japanese restaurant supply — premium tier uses fresh-grated authentic rhizome, but powder-based reconstituted wasabi serves the broader foodservice and conveyor-belt sushi market, with hon-wasabi proportion as a positioning lever.
