Since 1984, the amount of Japanese cedar pollen has been measured with Durham's pollen trap at Kochi Nokyo General Hospital.
In this study, the relation between pollen counts and meteorologicalfactors in the Kochi area during past 9 years was investigated. A correlation was found between the total count of Japanese cedar pollen in the Spring and the number of sunshine hours in July of the previous year. A correlation was observed between the day pollen scattering began and the mean temperature in January. Regarding wind direction, the amount of Japanese cedar pollen per day was higher when a north wind blew in Kochi.
These data suggested that the amount of Japanese c e dar pollen could be dependent on some meteorological factors. A further investigation would be worthwhile.
