Prediction of Pollen Diffusion for the Coming Spring

December 27, 2007

The Ministry of the Environment has made a prediction of the total diffusion of Japanese cedar and cypress pollen for the coming spring. The amount of airborne pollen varies depending on the area. From Tokai to Kanto and Tohoku regions the amount is expected to be more than that of this year, and from Hokuriku to Kyushu regions levels will remain unchanged or slightly less. The onset of Japanese cedar pollen diffusion is expected to be approximately the same time as, or a little earlier than that of the average year.
