The office found 10,331 wild opium poppy plants in April and May last year through its patrols and reports from local residents. This included a large area of natural growth where 3,000 plants were growing. It was a significant increase from the 3,746 found in 2021. Officials said that as many plants as possible need to be removed before the start of summer, because seeds scatter after the petals fall off. According to the Hyogo prefectural government, about 59,000 wild opium poppy plants were found in the whole prefecture last year. In May and June every year, the Health, Labor and Welfare Ministry and the Hyogo prefectural government conduct activities to eliminate illegally produced marijuana and opium poppies. Because the climate of Awaji Island is warm, opium poppies grow faster than in other places.
