Japan Names CBD Wax Over THC Limit, Fourth Warning in a Year
The health ministry asked buyers to hand in a CBD wax sold by a Tokyo company after Aichi Prefecture found Δ9-THC above the legal limit. It follows three similar warnings since May 2025.
This story is about Japan — not the country you picked in the header.
Key takeaways
- April 8, 2026: MHLW said a CBD wax sold by GREEN RUSH BY WEED Co. (Minato, Tokyo) had Δ9-THC over the residue limit.
- Aichi Prefecture found it in a February 2026 test purchase.
- The product is suspected to be a narcotic; owners are asked to surrender it.
- Earlier warnings: a CBD gummy (May 2025), a CBD drink (Nov 2025), a wax and a liquid (Dec 2025).
The product is listed as "Plus Weed Wax CBD 50% <OG Kush>", a 1,000 mg wax. According to the ministry's notice, Aichi Prefecture bought it in a February 2026 test purchase and its analysis found Δ9-THC over the limit. Because the product was likely sold nationwide, MHLW posted a public warning and a press release.
Why a CBD product counts as a narcotic
Since December 12, 2024, Japan has regulated THC content, not the plant part a product came from. Oils and powders may hold up to 10 ppm of Δ9-THC, water-based products 0.1 ppm, and all other forms 1 ppm. A wax is not a liquid oil, so it falls into the last category. Anything above its limit is legally a narcotic, so selling, buying, possessing or using it is a crime.
Fukuoka names CBD EAST GUMMIES (strawberry), distributed by Koutoku of Yokohama; a sales halt follows an inspection.
Tokyo names Pillow CBD Night Drink (50 ml) after a test purchase found Δ9-THC over the limit.
MHLW names AZALEA CBD WAX broad spectrum OG. KUSH CBD90% and CANNAXIA CBD LIQUID 01 Natural Hemp.
MHLW names Plus Weed Wax CBD 50% <OG Kush> from GREEN RUSH BY WEED.
The ministry said it knew of no health damage from the product. It noted that the product had not been confirmed as a narcotic but could be handled as one, and it gave owners a voluntary surrender and ownership-waiver form.
What buyers should do
Do not use or pass on the product; contact the regional narcotics control office or the prefectural pharmaceutical affairs division to hand it in. The earlier cases are on our Red List, and our guide to Japan's use offence explains why an over-limit CBD product carries the same legal risk as cannabis.
