In 1992, a nasal allergy questionnare study of randomly chosen junior high school students was conducted in China and Japan during high pollen seasons. The months in which pollen scatters the most in Japan are March and April, and in China August and September. One school in each area was chosen and 200'-400 students in each school were questioned. The schools chosen were in mountanous, agricultural areas (a suburb of Sheiang City in China, and Tsukechi-cho, Gifu Prefecture, Japan), and in urban areas (Beijing City and Sheiang City, China, and Nagoya City, Japan). In Beijing City 17.2% of the students had nasal symptoms (sneezing, nasal obstruction and nasal discharge), in Sheiang City 31.0%, in the surburb of Sheiang City 28.6%, in Nagoya City 28.1% and in Tsukechi-cho Gifu Prefecture 37.5%. It is obvious from these results that the students in the mountainous, agricultural areas had more symptoms of nasal allergy than did those in the urban areas. However, in Sheiang City and Nagoya City the percentage was higher than in Beijing City. Other allergy symptoms appearing in the questionnare included itching of the throat and eyes. Itching of the throat appeared to be higher in China, and itching of the eyes was higher in Japan. Among the students with nasal allergy symptoms, more consulted hospital doctors in Japan than in China. In both countries there was a family history of atopic disease in 15-'20% of the students with nasal allergy.
