Officers of the Hokkaido Police Organised Crime Countermeasures Section and Sapporo Nishi police station re-arrested two unemployed 30-year-old men from Higashi ward, Sapporo, on 11 August 2026, suspecting them of cultivating 1,083 cannabis plants for profit in a former factory building in Hidaka town, Hidaka District.[1][2]

The police put the drugs’ terminal street value at about 100 million yen and said it was the largest cannabis plant seizure from a single building anywhere in Hokkaido; the two, Renman Nakagawa and Yusuke Sato, had earlier in July been arrested on suspicion of possessing about 330 grams of dried cannabis for profit.[1][2] The suspicion is of profit-motivated cultivation under the Cannabis Cultivation Regulation Act; police did not say whether the men admit or deny the charges and are treating the case as organised cultivation and distribution.[1][2]
