Is Amanita muscaria legal in Japan?

Also known as: fly agaric

Legal status

Amanita muscaria is not a controlled substance in Japan. Neither the mushroom nor its active compounds, muscimol and ibotenic acid, is named in any list. The only fungi Japanese drug law designates are the 麻薬原料植物 in the Cabinet Order's 第三条, defined by what they contain, psilocybin and psilocin, and this species contains neither. Muscimol is an isoxazole and ibotenic acid an isoxazole amino acid; neither is a tryptamine, phenethylamine, cathinone, naphthoylindole or dibenzopyran, so no group clause reaches them. The constraint that does exist is food law: 食品衛生法第六条第二号 forbids selling, or making or importing for sale, a food 「有毒な、若しくは有害な物質が含まれ、若しくは付着し、又はこれらの疑いがあるもの。」, which is how a poisonous mushroom sold to be eaten is reached. Search record for this cell, run mechanically over the control lists (the e-Gov text of the narcotics Act, its Cabinet Order, enforcement order and rules, the Stimulants Control Act and its raw material order, the designated substances ordinance, the あへん法, the cultivation Act and the 麻薬特例法, and the MHLW and Narcotics Control Department list PDFs) on 2 October 2026: Amanita, ベニテングタケ, muscimol, ムシモール, ibotenic, イボテン酸, isoxazol, イソオキサゾール. None of those terms appears anywhere in them. Japan has no analogue statute. The only structural catch-alls in force are the designated substances ordinance's 第三百六十号 and 第三百六十一号 (naphthoylindole synthetic cannabinoids), 第三百六十二号 (cathinones built on 2-amino-1-phenylpropan-1-one), 第三百六十三号 to 第三百六十五号 (dibenzopyran cannabinoids with a 3 to 8 carbon side chain) and the deemed narcotics of 麻薬及び向精神薬取締法第二条第二項, which the Cabinet Order's 第六条 confines to two tetrahydrocannabinolic acids. Tables searched, each as at its own status date: the MHLW designation tables, narcotics tables status 6 September 2026 (麻薬の指定状況 令和８年９月６日現在: the Act's 別表第一 with 76 substances and the Cabinet Order's 第一条 with 171, counts that match the e-Gov text read on 2 October 2026); the MHLW designation tables, psychotropics tables status 3 October 2025 (向精神薬の指定状況 令和７年10月３日現在: the Act's 別表第三 with 10 substances and the Cabinet Order's 第四条 with 80, counts that match the e-Gov text read on 2 October 2026); the MHLW designated substances list status 6 September 2026 (the English list headed as of September 6, 2026, 2,484 substances; the Japanese index dates its own copy 令和８年８月27日現在 and gives the same total); and, as at 2 October 2026 on e-Gov, the 覚醒剤取締法 第二条 and its 別表 with the stimulant raw material Cabinet Order (平成八年政令第二十三号), the あへん法 and the 大麻草の栽培の規制に関する法律. Each of those lists can move by Cabinet Order or ministerial ordinance without an Act of the Diet, and the narcotics and designated substances lists moved as recently as 6 September 2026, so this absence is stated as at those dates and does not rule out a later amendment.

Consequences if caught

Capital exposure: none. No Japanese drug statute provides a death sentence: 死刑 appears in the main provisions of none of the 麻薬及び向精神薬取締法 (the Narcotics and Psychotropics Control Act), the 覚醒剤取締法 (the Stimulants Control Act), the あへん法 (the Opium Act), the 大麻草の栽培の規制に関する法律 (the Cannabis Plant Cultivation Act), the pharmaceuticals Act (the PMD Act) or the 麻薬特例法 (the Narcotics Special Provisions Act), each read on e-Gov on 2 October 2026. Japan has not abolished capital punishment: 刑法第九条 lists it among the principal punishments, 「死刑、拘禁刑、罰金、拘留及び科料を主刑とし、没収を付加刑とする。」, and 第百九十九条 provides it for murder. No drug offence attaches to the mushroom or to muscimol. Selling it as a food, or making or importing it for sale, is a breach of 食品衛生法第六条 punished by 第八十一条 with up to three years or a fine of up to three million yen, with both available where the circumstances warrant under 第八十一条第二項. Possessing it for one's own use is not an offence under either regime.

If prescribed or medical

Amanita muscaria has no prescription route and needs none; it is not a medicine in Japan and is in no controlled lane.

Documentation

A foreign prescription does not make a medicine importable into Japan, and none bears on Amanita muscaria; no narcotics permission applies either, because it is in no controlled lane. Food sold or imported for sale must not be toxic under 食品衛生法第六条, which is a commercial import rule rather than a traveller rule. Tables relied on for the absence: narcotics tables status 6 September 2026, psychotropics tables status 3 October 2025 and designated substances list status 6 September 2026.

Drug laws and enforcement change and vary within a country. This is not legal advice. Always confirm with Japan’s embassy or official drug authority before traveling; penalties can be severe, including imprisonment.
