Cedar Pollen Allergy in Japan

  • Today, I had itchy throat.


    I thought I caught a cold, but I also had a itchy eyes, so this was probably cedar pollen allergy.

    A cedar pollen allergy is the most common pollen allergy in Japan, and it is said that there are about 25 million people (almost 20% of the population) who suffer from it.

    The reason why there are so many cedar pollen allergy sufferer in Japan is that we have planted a large amount of cedars since the WW2 for the restoration.

    Cedars are have a high growth rate and possess high value as building materials.

    However, since they also have shedded their pollens too much, most Japanese people became cedar pollen allergy sufferers.

    Sometimes, the pollens reach the 300 km away from the planted place.

    Therefore, the cedar pollen count becomes part of the daily weather report during this time of year.

    Fortunately, Japan is planning to cut down the cedars, and replant the other trees that have less pollens from this year.

    I can’t wait for the next year.
