Influencer Yamatorino was re-arrested by the Tokyo Metropolitan Police on October 7, 2026, on suspicion of using cocaine and ketamine, following an initial arrest for alleged cocaine possession in her Roppongi apartment last month, Bengo4.com reported. The case highlights how shifting prosecutors’ charges from cocaine to ketamine impacts potential sentencing under narcotics laws.

Tokyo Prosecutors Charge Ketamine Possession Over Cocaine

Yamatorino was originally arrested alongside a male acquaintance on September 15, 2026, at her residence in Tokyo’s Roppongi district on suspicion of possessing approximately 0.4 grams of cocaine, according to Bengo4.com. Investigators seized 21 bags containing white powder and a straw used for ingestion from the apartment. Despite the initial cocaine arrest, the Tokyo District Public Prosecutors Office formally indicted her on October 6 for possessing roughly 0.024 grams of ketamine. Prosecutors stated the indictment decision was based on the evidence available at that stage.

Following the October 6 indictment, the Metropolitan Police re-arrested Yamatorino on October 7 for alleged use of both cocaine and ketamine around the time of the initial arrest. Testing revealed both substances in seized powder samples and confirmed positive results in her urine analysis. While Yamatorino reserved her plea, her male acquaintance admitted to the re-arrest allegations regarding cocaine, differing from his initial denial.

Ketamine Possession and Use Carry Seven Year Sentences

Ketamine has been regulated as a narcotic in Japan since January 2007. Under Article 66, Paragraph 1 and Article 66-2, Paragraph 1 of the Narcotics and Psychotropics Control Act, both possession and use carry sentences of up to seven years of penal servitude, matching the statutory penalty for cocaine. However, the legal outcome depends heavily on whether prosecutors establish intent to sell.

For a small amount intended for personal use by a first-time offender, practical application frequently results in suspended sentences. Data from the 2025 White Paper on Crime shows that out of 771 individuals receiving fixed-term sentences for narcotics violations in district courts during 2024, 551 received suspended sentences, as detailed by Bengo4.com.

Commercial Intent Increases Penalties for Narcotics Offenders

If authorities prove commercial intent, the statutory penalty increases to between one and ten years of penal servitude under Article 66, Paragraph 2 of the same legislation, alongside potential fines based on extenuating circumstances. Determining commercial intent relies on factors such as total quantity, the presence of digital scales or small plastic bags, and digital communication logs indicating repeated transactions. While reports did not mention scales or large sums of cash in Yamatorino’s case, the discovery of 21 individual bags of powder remains a focal point for investigators examining potential small-pack distribution.

Legal constraints prevent courts from independently determining commercial intent if prosecutors file charges solely for simple possession. To pursue a heavier sentence under commercial intent provisions, prosecutors would need to modify the indictment.

Investigators have not yet clarified whether prosecutors will seek to alter the indictment to include commercial intent charges based on the 21 recovered powder bags.
