Pollen Season of Japanese Cedar and Cypress to End

April 26, 2007

The Japanese cedar and cypress pollen season is expected to end in early May in Japan.

The cedar pollen concentrations in air have already dropped to a zero level in March in the Kyushu, Chugoku and Shikoku regions, and are approaching that level in mid April in the Kinki region. In parts of the Tokai, Hokuriku and Kanto-Koshinetsu regions, pollens are still observed; but they are expected to recede before long. In the Tohoku region, the cedar pollen season is expected to end at the end of April.

The cypress pollen levels are expected to recede at the end of April in western Japan, and early May in the Tohoku region, except for the high-mountain areas.
