Is CBD legal in Japan for tourists?
Short version: CBD products may be permitted in Japan when they meet the applicable residual-THC limits. Products above those limits are controlled, and border rules are strict. Here's what visitors to Tokyo need to know.
The short answer
CBD products that stay within Japan's residual-THC limits may be permitted to buy and use in Japan, including for tourists. Products above those limits are controlled. Bringing cannabis or an unverified cannabinoid product into Japan, even one that is legal in your home country, can carry serious legal risk.
CBD vs THC — the line that matters
CBD (cannabidiol) is non-intoxicating and is not a controlled narcotic in Japan. THC (tetrahydrocannabinol) is the psychoactive compound in cannabis and is tightly controlled. The entire question of legality comes down to one thing: how much THC, if any, a product contains.
What changed in 2024
Japan's Cannabis Control Act was reformed, with the key provisions taking effect on 12 December 2024. Two changes matter most for consumers:
- Ingredient-based rules. Legality is now judged by a product's THC content, not by which part of the plant it came from. CBD products that stay within the residual-THC limits are permitted.
- A new 'use' offence. Using illicit cannabis (THC) is now a crime in itself, alongside the existing bans on possession and trafficking. Penalties are severe.
The THC limits, in plain numbers
Under the rules in force since December 2024, these product-category thresholds determine whether a product falls outside narcotics control on the basis of its residual Δ9-THC level. A product above the applicable threshold is treated as a narcotic:
| Product type | Residual THC limit |
|---|---|
| Oils & powders | 10 ppm (10 µg/g) |
| Other products (solids, edibles, cosmetics) | 1 ppm |
| Aqueous (water-based) solutions | 0.1 ppm |
This is why a current, product-specific Certificate of Analysis (COA) matters. It helps you assess the tested batch against the applicable category limit instead of relying only on a 'THC-free' label.
What this means if you're visiting Tokyo
If you're a tourist, the practical rules are simple:
- A CBD product within the applicable residual-THC limit is not treated as a narcotic on that basis; its other ingredients and rules still matter.
- Keep the original packaging and batch-matched COA. A COA supports review but does not, by itself, prove overall legality.
- Do not bring cannabis, THC vapes, THC edibles or an unverified cannabinoid product into Japan. Rules and penalties apply to visitors.
- Do not assume a product is acceptable in Japan because it was legal where you bought it.
- Note: sales are restricted to ages 20+, and you may be asked for valid ID.
How to buy CBD safely in Tokyo
Buy only from sellers who can show you third-party lab results. Look for a clear COA, a stated THC content within the limits above, and a seller who will answer questions about sourcing. If a vendor can't produce a COA, treat that as a red flag. Our guide to reading a cannabinoid COA explains what to match before ordering.
We make available COA documentation for the products we offer. If you'd like help reviewing a product before ordering, just message us on WhatsApp.
Frequently asked
Can I bring my CBD gummies or oil from home into Japan?
Import rules are strict. A product may exceed Japan's residual-THC limits even if it is legal elsewhere. Check current official customs and health-ministry guidance before travelling; do not bring an unverified product.
Is CBD oil legal to buy in Tokyo?
A CBD oil may be permitted if that specific product meets Japan's applicable residual-THC limit and other rules. Review the product's current COA and official guidance.
