Atmospheric cedar pollen in the southern region of Okayama Prefecture (situated in south‐western Japan) has been counted since 1988. Pollen of different species of the Taxodiaceae family ( Cryptomeria japonica, Sequoia sempervirens and Metasequoia glyptostroboides ) and Japanese juniper ( Juniperus rigida ) in the Cupressaceae family, which are propagated mainly in the southern region of Okayama Prefecture, were found among the atmospheric pollen. Scratch tests using the pollen extract from Taxodiaceae and Cupressaceae were performed on children with bronchial asthma. Forty (25%) and 30 (18.8%) of the 160 patients reacted positively to an allergen extract from the pollen grains of Japanese cedar ( Cryptomeria japonica ) and Japanese juniper, respectively.
