Market
Sun-dried radish (kiriboshi daikon) is a traditional Japanese dried-vegetable product used as a shelf-stable cooking ingredient in households and commercial prepared-food applications. Japan has domestic seasonal production, with Miyazaki commonly referenced as a major producing area and winter drying activity typically occurring from late November through February. Because imported dried vegetables are part of supply, importers must manage Food Sanitation Act import notification and compliance checks at MHLW quarantine stations before the goods can be sold. Depending on the product’s processing status and MAFF plant-quarantine import conditions, a phytosanitary certificate and plant-quarantine inspection may apply.
Market RoleDomestic consumption market with domestic production and imports

Risks
Food Safety HighNon-compliance with Japan’s residue standards (Positive List System for agricultural chemical residues) can block distribution and trigger rejection or disposal/return following quarantine-station checks for imported foods.Implement pre-shipment residue control (supplier pesticide-use controls plus third-party testing aligned to Japan standards) and maintain documentation to support MHLW quarantine-station review.
Regulatory Compliance HighFailure to complete Food Sanitation Act import notification and related quarantine-station procedures can prevent the product from being sold for business purposes in Japan.Use an experienced Japan importer of record to file the Notification Form for Importation of Foods, etc. for each shipment and resolve any inspection requirements before customs release for sale.
Plant Quarantine MediumDepending on processing status and MAFF import conditions, dried radish products may still fall under plant-quarantine requirements; missing phytosanitary documentation or inspection non-compliance can cause detention or rejection.Confirm MAFF Plant Protection Station import conditions for the exact product form and origin before shipment; obtain a phytosanitary certificate where required.
Labeling MediumNon-compliant Japanese labeling for foods sold in Japan can delay distribution and require relabeling or corrective actions.Prepare Japan-compliant Japanese labels in advance (including required fields for processed foods as applicable) and align label content with the importer’s compliance checklist.
Quality MediumMoisture uptake during storage or transit can degrade product quality and raise mold/foreign-odor risks in dried vegetables.Use moisture-barrier packaging and humidity control (e.g., desiccants as appropriate), and specify dry, clean, odor-free storage and container-loading conditions.
FAQ
What is the core compliance step to import sun-dried radish for commercial sale in Japan?For commercial imports, the importer must submit the “Notification Form for Importation of Foods, etc.” under the Food Sanitation Act to the MHLW quarantine station at the port of entry and complete the associated document review (and any required inspection) before the goods can be sold.
Why are pesticide residue controls a deal-breaker for Japan-bound shipments of dried radish products?Japan applies residue standards under the Positive List System for agricultural chemical residues in foods, and products exceeding applicable standards are not permitted for distribution. This makes residue management and evidence (supplier controls and, where appropriate, testing documentation) critical for market access.
Is a phytosanitary certificate required to ship dried radish products into Japan?MAFF plant-quarantine rules generally require a phytosanitary certificate and import inspection for plants and plant products, but processed products may be exempt when they pose no risk of introducing harmful pests. Whether a specific dried radish product requires plant-quarantine procedures depends on the exact product form and origin, so importers should confirm MAFF import conditions in advance.
