Can you bring CBD to Japan? Yes, CBD itself is not banned. But Japan sets THC limits so low that many CBD products sold openly in other countries can count as narcotics on arrival, and importing a narcotic can mean 1 to 10 years in prison. So the real question isn't "CBD or no CBD". It's how much THC is hiding in the bottle, and whether you can prove it.

What changed
Japan rewrote its cannabis rules in a 2023 law (Act No. 84 of 2023) that took effect on 12 December 2024. Since then, cannabis and THC are regulated as narcotics under the Narcotics and Psychotropics Control Act, and a cannabis-derived product counts as a narcotic unless the Δ9-THC left in it is at or below a set limit (MHLW notice 医薬監麻発1004第3号, 4 Oct 2024; Japan Customs Answer 2005, accessed 24 Oct 2026).
The limits are set in Article 2 of a Cabinet Order, and they depend on what form the product takes (Cabinet Order No. 238 of 1990, Art. 2, e-Gov, accessed 24 Oct 2026):
| Product type | THC limit | Examples (official) |
|---|---|---|
| Oils that are liquid at room temperature, and powders | 10 ppm | CBD oil, hemp seed oil, cosmetic oil, CBD powder |
| Water-based liquids | 0.1 ppm | Soft drinks, alcoholic drinks, skin lotion |
| Everything else | 1 ppm | Sweets and gummies, tablets, butter, vape liquids, creams, balms, shampoo, jelly |
The examples come from the health ministry's notice and the Narcotics Control Department's product guide (MHLW notice, 4 Oct 2024; NCD product categories, 1 Jun 2026 edition). Capsules are judged by what's inside them, and sheet masks by the liquid they're soaked in (MHLW notice, 4 Oct 2024).
For scale: a label that says "less than 0.3% THC" still allows up to 3,000 ppm. That's 300 times Japan's limit for oil and 30,000 times its limit for a CBD drink. Your "totally legal" gummies from home may be a narcotic by the time the wheels touch down at Narita.
Above the limit, the product is legally a narcotic and can't be imported (Japan Customs Answer 2005).
And one more change: since 1 June 2026, CBN is a "designated substance". Making, importing, selling, possessing and using CBN products is banned, outside a narrow medical procedure (MHLW press release, 18 Mar 2026; NCD CBD page, accessed 24 Oct 2026). Some CBD blends list CBN too, so read the label twice.
What it means for travelers
The burden of proof is on you. Tokyo Customs, writing about parcels, says that if you can't show a CBD product isn't a narcotic, it can't be imported or sent back. You can give up ownership of it, and that's about it (Tokyo Customs, "18. CBD-related products", accessed 24 Oct 2026).
The pre-check exists, but it's slow and it isn't a free pass. The Narcotics Control Department (NCD) offers a voluntary check, by email to CHECKCBD@mhlw.go.jp, for people planning to import CBD or CBG products (NCD CBD page). Its official guide says (NCD guide, 1 Jun 2026 edition):
- You need a certificate of analysis for the exact batch, showing the product type in Japan's categories (oil, powder, water solution or other), the test date, the lot number, the analysis method, the detection and quantification limits, and the signature and title of the lab's responsible person.
- Answers can take one to two months. Not ideal if your flight is on Thursday.
- A "not a narcotic on paper" reply doesn't exempt you from inspection. If Customs finds a controlled substance anyway, you can still be prosecuted.
- Each import is a separate check, even for the same product and batch.
The penalties are set by law, and they're not small. Under the Narcotics and Psychotropics Control Act (e-Gov, Act No. 14 of 1953, accessed 24 Oct 2026):
- Importing a narcotic such as an over-limit THC product: 1 to 10 years in prison (Art. 65). Attempts count.
- Possessing it: up to 7 years (Art. 66).
- Using it: up to 7 years (Arts. 27 and 66-2).
On top of that, smuggling prohibited goods under the Customs Act carries up to 10 years and/or a fine of up to ¥30 million (Japan Customs, Customs Act penalty provisions, accessed 24 Oct 2026). CBN, as a designated substance, carries up to 3 years or a fine of up to ¥3 million (MHLW press release, 18 Mar 2026).

Vapes are the strictest case. CBD vape liquids fall under "everything else", so the limit is 1 ppm. Our vape guide for Japan covers the devices, nicotine and the plane rules.
What hasn't changed
- "It's legal where I bought it" is not a defence. Japan applies its own THC limits, whatever the label or the law at home says (Japan Customs Answer 2005).
- "It's only CBD" doesn't settle it either. The question is always the THC left in the product (MHLW notice, 4 Oct 2024).
- An NCD reply isn't an approval. The NCD says products can't be labelled as "approved" or "certified" by the ministry after a check, or carry its logo (NCD guide, 1 Jun 2026 edition).
- Cannabis itself is still a serious crime. Flower, oil, gummies or cartridges with THC over the limits are narcotics. There's no tourist exemption; the only carry-in exception is the health minister's permit described above (e-Gov, Act No. 14 of 1953).
The safe packing list: leave CBN products at home. Bring CBD only if you can show, batch by batch, that the THC is under the limit for its category. Never carry someone else's "wellness" products. When in doubt, the safest souvenir is the one you didn't pack.
