Prediction of the Total Pollen's Diffusion for the Coming Spring

December 22, 2006

The Ministry of the Environment predicts that the total diffusion of the Japanese cedar and cypress pollen in the coming spring will be about 20% to 100% of a normal year. The prediction also says that the onset of the Japanese cedar bloom and pollen diffusion will be about the same time as, or a little later than that of the average year.

The amount of airborne pollen varies depending on the area. In the Hokkaido and the northern part of the Tohoku regions, next spring, it is expected to be at the normal year average. In the southern part of the Tohoku region, the amount is expected to be half that of the average year; in the Kanto - Koshinetsu region, to be about 25% of a normal year; in the Hokuriku and the Tokai regions, to be about 20 to 50%; in the Kinki region to be about 30 to 60%; in the Chugoku and the Shikoku regions to be about 50 to 80%; and finally in the Kyushu region, to be at the normal year average or a little less.
