As spring approaches, many in Japan brace for the seasonal wave of cedar pollen that often causes allergies. According to a private weather forecasting company, this year's pollen count is expected to exceed the average starting from early February. However, there is positive news as facilities dedicated to cultivating cedar trees with significantly lower pollen production have come to light. Located in Tsu City, Mie Prefecture, the Mie Prefectural Forestry Research Institute is nurturing around 300 cedar trees that produce less than 1% of the typical pollen, along with other specific varieties that yield even fewer allergens.

The cultivation of low-pollen cedar and cypress trees is being championed by national research institutes and prefectural governments across Japan. Among the notable developments is the existence of 148 varieties of low-pollen cedar and 55 varieties of cypress. The main researcher, Emi Higashikawa, expressed that visitors are often surprised to learn about the existence of these specially cultivated trees. As efforts continue in various regions of Japan, these trees might contribute to reducing allergy issues faced by many during the pollen-heavy seasons.

The initiative for replanting low-pollen cedar not only addresses public health concerns but also represents a significant shift in forest management practices in Japan. The strategy could lead to a healthier environment and improved quality of life for those affected by seasonal allergies, and reflects growing awareness regarding the importance of biodiversity and ecological balance in forestry practices. As the project progresses, it remains to be seen how effective these low-pollen varieties will be in combating the perennial issue of pollen allergies in Japan, inviting ongoing community and scientific interest in the field of forestry.
