FAQ: sourcing traditional materials from Japan

Q. What does 'traditional' mean for Japanese ingredient sourcing?

In this catalog, 'traditional materials' refers to ingredients made by methods documented in Japan for 100+ years — kioke (cedar barrel) aged soy sauce, naturally fermented hon-mirin, Hatcho miso (made by only two licensed producers), Yoshino kudzu starch, and shio-koji. These typically command 3–10x the price of mass-produced equivalents.

Q. Are there licensing or trademark constraints on traditional ingredient names?

Yes — several names are regional collective trademarks or GIs. Examples: 'Hatcho miso' is restricted to two Aichi producers; 'Yoshino kudzu' refers to Nara-prefecture-specific kudzu; certain sake yeast strains (Kyokai-7, Kyokai-9) are licensed by the Japan Brewers Association. Confirm trademark status before using these names in marketing.

Q. What is the lead time for kioke-aged soy sauce or 2-year-aged miso?

Naturally aged products (1–3 year fermentation) ship from finished inventory only — there is no way to accelerate aging. Suppliers typically work on annual allocation contracts with limited spot availability. Plan 12+ months ahead for committed volumes.

Q. Do traditional Japanese ingredients meet EU and US food safety standards?

Yes — major traditional fermented Japanese foods (soy sauce, miso, mirin, vinegar) have established export history to EU/US and are widely accepted. EU shipments require allergen labeling for soy/wheat. Salt content in traditional fermented foods is high; some markets (e.g., UK FSA targets) may flag this on nutrition labels.
