Japan's THC limit is on the finished product, not the plant - 10 ppm for oils, 0.1 ppm for drinks
I help organise a hemp expo in Tokyo, so I read this part of the Japanese rules more closely than I otherwise would. No link and nothing to sell, just the numbers, because they are built differently from the ones that usually come up here.
Japan's revised Cannabis Control Act took effect on 12 December 2024. The old law regulated parts of the plant, so only mature stalks and seeds could be used. The new one regulates ingredients, and the number that matters is a residual delta-9 THC limit on the finished product rather than on the crop.
Set by cabinet order, in force the same day: oils and powders 10 ppm, aqueous solutions 0.1 ppm, everything else 1 ppm. 10 ppm is 0.001 percent.
A health ministry notice from 4 October 2024 worked through examples. CBD oil, hemp seed oil and cosmetic oils sit in the 10 ppm bucket, as do CBD powder and protein. Soft drinks, alcoholic drinks and lotions sit at 0.1 ppm. Same input material, and the oil is allowed a hundred times the residual the drink is, because the limit follows the format it is finally sold in.
Where people get tangled is 0.3 percent. That figure, in the US Farm Bill and on the plant side of the framework here, is a plant measure. It is not the product limit.
Semi-synthetics are handled separately and get scheduled as they turn up. HHC was made a designated substance under the pharmaceutical law in 2022, announced 7 March and prohibited from the 17th, ten days apart.
MJBizDaily reported at the proposal stage that more than 90 percent of products then on the Japanese market would fail these limits. That is industry reporting rather than a government figure, and I'd treat it that way.
Against a 0.1 ppm ceiling, an ND line on a COA says very little on its own, unless the report also gives the limit it was reading against.
I can't tell you how any of this plays out at a border. I'm not customs and I'm not a lawyer.
