Market
Dried perilla (shiso) leaf products in Japan are primarily positioned as shelf-stable seasonings (e.g., shiso-based furikake/rice seasonings) for household and foodservice use. Domestic shiso leaf supply is strongly concentrated in facility-grown production, with Aichi Prefecture ranked top by shipment volume and share for shiso (ooba/green shiso) in Japan. Major Japanese seasoning brands market shiso-leaf products (red shiso and green shiso variants), and ingredient origin disclosure can include both Japan and China depending on the SKU. For imported dried perilla leaf products and blends, Japan’s import notification procedures and pesticide-residue compliance under the positive list system are central market-access considerations.
Market RoleDomestic producer and consumer market; imports and cross-border sourcing are used for some processed shiso-leaf seasoning SKUs
Domestic RoleCulinary herb/seasoning ingredient used widely in rice seasonings (furikake/maze-gohan) and as a flavor-and-color component in processed foods
SeasonalityYear-round retail availability is typical because the product is shelf-stable; upstream leaf production includes facility cultivation that supports steady supply.
Specification
Primary VarietyRed shiso (aka-jiso) for red shiso seasonings
Secondary Variety- Green shiso (ao-jiso) for green shiso seasonings
Physical Attributes- Aroma intensity and color retention are key quality cues for shiso-leaf seasonings.
- Uniform particle size (flakes/powder) and low foreign-matter risk are important for consumer acceptance.
Packaging- Small retail packs (bottles/sachets) and larger institutional packs are both used for shiso seasonings in Japan.
Supply Chain
Value Chain- Contracted shiso cultivation and procurement → raw material handling → seasoning/formulation → drying (or semi-drying) → packaging (retail and institutional formats) → domestic distribution
Temperature- Ambient-stable but moisture sensitive: storage instructions commonly emphasize avoiding direct sunlight and high temperature/humidity.
Shelf Life- Unopened shelf life for branded shiso seasonings is commonly around 12–13 months depending on SKU and format.
Risks
Regulatory Compliance HighNon-compliance with Japan’s Food Sanitation Act requirements—especially pesticide residue standards under the positive list system—can lead to import rejection or mandatory disposal/return of shipments at the quarantine station stage.Align supplier pesticide programs to Japan MRLs/positive list expectations; require pre-shipment documentation and risk-based residue testing for high-risk origins/lots before booking shipment.
Food Safety MediumDried leaf seasonings are vulnerable to foreign-matter and hygiene failures (e.g., physical contaminants) that can trigger quality claims or enforcement actions.Use HACCP-based controls with sieving/foreign-matter control and validated packaging integrity; maintain supplier audits and incoming inspection.
Plant Quarantine MediumDepending on how the product is classified as a plant/plant product versus a sufficiently processed product, MAFF plant quarantine inspection and phytosanitary certificate requirements may apply; misinterpretation can cause clearance delays or refusal.Confirm import conditions with MAFF Plant Protection Stations (by origin and processing state) prior to shipment; align documents and product description with the determined category.
Documentation Gap MediumIngredient-origin disclosure and labeling inconsistencies (e.g., origin of shiso leaf ingredient, additive declaration) can create compliance and customer-audit issues in Japan’s retail/institutional channels.Prepare a Japan-ready specification pack (ingredients, additives, allergens, origin statements, labeling text) and run a pre-import label/legal review with the Japanese importer.
Standards- HACCP-based hygiene management (manufacturer-level food safety system)
FAQ
What is the core import procedure for dried perilla (shiso) leaf seasonings entering Japan for sale?For business imports, the importer must submit a “Notification Form for Importation of Foods, etc.” to an MHLW quarantine station under the Food Sanitation Act. The quarantine station conducts document examination and may require inspections before the goods can proceed in the import process.
What is the main compliance risk that can block imports of dried perilla leaf products into Japan?Pesticide residue non-compliance is a major blocker: Japan applies a positive list system for agricultural chemical residues in foods, and foods exceeding residue standards are prohibited from sale/import. Import inspections can include residue testing at the border.
Do dried perilla leaves always need a phytosanitary certificate and plant quarantine inspection in Japan?Not always. MAFF explains that plants and many plant products generally require plant quarantine procedures and a phytosanitary certificate, but processed products that pose no threat of introducing harmful pests may not require import inspections. Whether dried perilla leaves qualify depends on the exact processing state and origin, so importers should confirm conditions with MAFF Plant Protection Stations.
