Is weed legal in Tokyo, Japan in 2026?

No. Since 12 December 2024, cannabis is classified as a narcotic under Japan's Narcotics and Psychotropics Control Act. Possession, transfer and use each carry up to 7 years in prison, and importing it carries 1 to 10 years. There is no personal-use allowance, no dispensaries and no recreational or medical cannabis programme for visitors.

What happens if you get caught with weed in Tokyo?

Expect arrest, not a fine. Japanese police can hold a suspect for up to 23 days before prosecutors decide whether to indict, usually with a urine test and repeated questioning. First-time possession of a small amount commonly ends in a suspended prison sentence, but a foreign national convicted of a drug offence faces deportation and can be refused entry to Japan in the future.

Can tourists be charged in Japan for cannabis smoked before the trip?

Use became a separate crime on 12 December 2024, and police treat a positive urine test as evidence of it. The first arrests for use in Tokyo followed urine tests in March 2025. If you test positive after arriving in Japan, you may have to argue from custody that the use happened abroad.

Is CBD legal in Tokyo?

Only if THC residue stays under Japan's limits: 10 ppm (0.001%) for oils and powders, 0.1 ppm for water-based drinks and 1 ppm for other products such as edibles. Most CBD sold in the US or EU is legal there at up to 0.2–0.3% THC, far above Japan's limits, so bringing it in can count as importing a narcotic.

Are there cannabis dispensaries or coffee shops in Tokyo?

No. Tokyo has no legal dispensaries, coffee shops or social clubs. CBD shops may sell only compliant low-THC products, and synthetic cannabinoids such as HHCH have been banned as designated substances since December 2023, carrying up to 3 years in prison or a fine of up to ¥3 million.

⚖️ Legal Status at a Glance — Tokyo, Japan

Legal Use Illegal (up to 7 yrs)

Possession Criminal Offence

CBD Products Strict THC Limits

Import / Trafficking 1–20 Years

Regulation Status Tightened (Dec 2024)

Overview

Japan welcomed a record 42.7 million foreign visitors in 2025, and most pass through Tokyo's Narita and Haneda airports. Cannabis is illegal in every recreational form. There is no personal-use allowance, no dispensary and no tolerance for tourists.

The one fact every visitor needs: since 12 December 2024, using cannabis is itself a crime in Japan, carrying up to 7 years in prison. A positive urine test can support the charge, even if you carry nothing. An arrest in Tokyo does not end with a fine at the police box. It can mean up to three weeks in a police cell, a criminal record and deportation.

The Law Right Now

The December 2024 amendments reclassified cannabis and THC as narcotics under the Narcotics and Psychotropics Control Act. The old Cannabis Control Act was renamed and now mainly regulates hemp cultivation licences. Under Article 66, possession, transfer or receipt carries up to 7 years in prison, up from 5. Under Article 66-2, use now carries up to 7 years. Doing either for profit raises the maximum to 10 years plus a fine of up to ¥3 million.

Importing is treated more harshly. Bringing cannabis into Japan without a licence carries 1 to 10 years under Article 65, and 1 to 20 years if done for profit. Unlicensed cultivation carries the same ranges.

CBD is legal only below strict THC residue limits: 10 ppm (0.001%) for oils and powders, 0.1 ppm for water-based drinks, and 1 ppm for other products, including edibles. Products legal in the US or EU at 0.2–0.3% THC are many times over these limits. Semi-synthetic cannabinoids are banned separately as designated substances under the Pharmaceuticals and Medical Devices Act. HHCH was added in December 2023 after gummies handed out at a festival in Koganei, western Tokyo, left people ill. Violations carry up to 3 years or a fine of up to ¥3 million.

The reform opened a legal pathway for approved cannabis-derived medicines, but as of September 2026 the CBD epilepsy drug Epidiolex has not received final Japanese approval. Foreign medical cannabis prescriptions are not recognised.

Realistic Consequences

Japan does not confiscate and warn. A tourist found with even a small amount is normally arrested. Police can hold a suspect for up to 72 hours, then prosecutors can request 20 more days, for a total of about 23 days before an indictment decision. Expect a urine test, daily interrogation and no lawyer present during questioning. For a first-time offender with a small personal amount, a common outcome is a suspended prison sentence. That still means a conviction, which makes a foreign national liable to deportation under the Immigration Control Act and can bar future entry to Japan.

The trigger is not only what you carry. In March 2025, Tokyo police made the first arrests under the new use offence after urine tests. At the border, sniffer dogs and parcel checks catch small amounts as well as couriers. On 5 September 2026, two 25-year-old American women were arrested at Haneda with about 30 kg of cannabis in their suitcases. Nationwide, police arrested a record 6,832 people in cannabis cases in 2025, about 70% of them under 30.

📡 Regulation Pulse

2 December 2023: HHCH banned as a designated substance after the Koganei gummy poisonings.
12 December 2024: cannabis moves under the Narcotics and Psychotropics Control Act; a use offence (up to 7 years) and ppm-based CBD limits take effect.
March 2025: first arrests under the use offence in Tokyo, based on urine tests.
February–April 2026: customs report a record 1,531 kg of cannabis seized in 2025, and police report a record 6,832 cannabis arrests.
April 2026: Jazz Pharmaceuticals and Nippon Zoki sign a deal to bring Epidiolex to Japan; approval is still pending.

Public Sentiment

No reliable recent national poll supports legalisation. Drug use carries heavy social stigma, and universities such as Waseda warn students of expulsion. The government responded to rising youth use, with more than 40% of under-30s questioned in 2025 having bought through apps such as X and Telegram, by tightening the law rather than relaxing it.

Practical Advice for Visitors

Bring no cannabis, THC vapes or edibles into Japan, in any amount. Import carries 1 to 10 years, and Narita and Haneda customs check bags and parcels closely.

Leave your home-country CBD at home. Unless a lab certificate shows it meets Japan's ppm limits, treat it as a narcotic.

Stop using cannabis well before you fly. Use is now a crime, and a positive urine test after arrival can support a charge.

Do not buy from street contacts, nightlife offers or social media sellers. Buyers are arrested too, and unregulated "gummies" have put people in hospital.

Do not mail cannabis products to your hotel. Parcels are screened, and the recipient is the one arrested.

If you are arrested, ask for your embassy and a lawyer immediately. Do not sign a Japanese-language statement you cannot read.
