Poppy Seeds may require documentation or declaration
Details
Poppy Seeds may require documentation or declaration. Enforcement in Japan carries fines from JPY 100,000 to JPY 5,000,000 under Customs Law (Kanzeihō) Art. 110, Art. 111 (ordinary personal cases are handled as civil infringements). Restricted status means compliant carriage is achievable with the right paperwork and quantities; the practical risks are seizure, duty, and delay rather than criminal liability for a good-faith traveller. Arrival checks are carried out by Japan Customs (Ministry of Finance); when in doubt use the declare (red) channel — declared goods at worst attract duty or surrender, while undeclared goods attract penalties. Leaving Japan with poppy seeds is a separate question: allowed — Culinary poppy seeds may be exported from Japan freely; several destinations prohibit them, so check the arrival side.

Practical advice
Japan restricts import of Poppy Seeds. Personal-use retail-packaged quantities may clear with declaration and inspection but home-prepared, loose-packed, or above-personal-use quantities typically require a Phytosanitary Certificate (plants) or Export Health Certificate (animal-origin). Verify current rules with Japan Customs (Ministry of Finance) before travel — biosecurity rules change frequently on specific commodities.
