Japan on Tuesday unveiled a comprehensive policy package to tackle hay fever caused by pollen from cedar and cypress trees, aiming to halve emissions over the next 30 years.
As hay fever is estimated to affect more than 40 per cent of the population, the government plans to reduce areas of planted cedar by around 20 per cent over the next decade by cutting 70,000 hectares (173,000 acres) of the trees per year, compared with the current level of 50,000 hectares.
To reduce the impact of pollen allergens that trigger symptoms such as a runny nose, sneezing and itchy eyes mainly during the spring season, more than 90 per cent of young cedar trees would be replaced in 10 years with species that release less pollen.
“It is necessary to maintain a strong focus on the issue and implement policies steadily as this is not something that can be solved overnight,” Prime Minister Fumio Kishida said at a ministerial meeting on hay fever held at his office on Tuesday.
The measures are expected to be incorporated into the annual economic policy blueprint, scheduled for compilation in June.
