- Post-WWII mass planting of Japanese cedar and cypress, intended for reforestation and timber, has led to widespread pollen allergies affecting 43% of Japan's population, causing significant economic and health impacts.
- Japan has launched a national initiative to reduce pollen by 50% in 30 years, including replacing monoculture plantations with diverse forests, exemplified by local projects in places like Kobe and Nishiawakura that restore biodiversity and create sustainable forestry economies.
- Efforts face challenges such as scale, cost, and climate goals, with additional strategies like pollen forecasting, medical treatments, and a new forestry tax, while ensuring sustainable practices to avoid environmental harm and maintain carbon sequestration.
