Hay fever in Japan

If you visit Japan in March and April, you will tend to see many people wearing masks. This is not due to air pollution or due to colds, but it is probably because many people are hay fever sufferers.

The Japanese hay fever phenomenon was created by a forestation policy decision made shortly after World War II. This policy involved planting Japanese cypress and cedar which were an important resource for the construction industry.

The over-planting of a limited variety of trees and the resulting production of a single type of pollen is thought to have been a major contributing factor to the increasing allergic symptoms suffered by one third of the population.

Kaori Ishibashi is a Japanese language teacher at JOI and she reads and writes this language learner's blog. Listen to Ishibashi sensei read the article and learn some useful Japanese vocabulary from this blog.

Hay fever




日本では春になると花粉症悩まされる人が多いです。 日本人の3人に1人が花粉症患者だそうです。 なぜそんなに花粉症の人が多いのでしょうか。

花粉症は、植物の花粉が原因で鼻水くしゃみ目のかゆみなどのアレルギー症状が起こるものです。 日本の春の花粉症の原因は主にスギヒノキの木だそうです。秋の花粉症の原因は主に雑草だそうです。

症状のひどい人は薬を飲んだり、目薬をさしたりしています。この時季は多くの人がマスクをしています。マスクは見た目はあまりよくありませんが、最近は性能のいいマスクが売られていて、効果が高いようです。それに、最近では花粉対策の眼鏡をかけている人もよく見かけます。 海外から来る人も、日本に来て初めてアレルギー症状が出たという人が多いです。

Hay fever

When spring comes to Japan, there are a lot of people who suffer from hay fever. One in three people in Japan are patients with hay fever. Why are there so many people with hay fever?

Hay fever is when allergic symptoms like runny noses, sneezing, itchy eyes etcetera arise, caused by pollen from plants. In Japanese spring, the main cause of hay fever is from Japanese cedar and Japanese cypress trees. In autumn the causes of hay fever are weeds.

For people who suffer from terrible symptoms, they take medicine and use eye drops too. And in this season, many people wear masks. Masks do not look very nice, but recently, there are high-performance masks on sale and these are apparently very effective. On top of this, you can often see people wearing anti-hay fever glasses. There are also many people who visit Japan from foreign countries and when they arrive here, they get their first allergic symptoms.

In Japan between March and April, the cherry blossoms bloom, and many tourists visit Japan. It is a very beautiful season but, if you are worried about allergies, please try some of the convenient hay fever goods.

Hajimemashite, my name is Kaori Ishibashi.
I live in Ibaraki city, in Osaka prefecture, with my husband, son and daughter. Ibaraki city is in between Osaka and Kyoto and is in a very convenient location. Before I was married, I went to Canada and Spain as an exchange student. So I too love to study languages.
Since my children are still so young, I cannot readily go abroad, so I am really glad of the opportunity to communicate with people from various countries through JOI. Let's study Japanese together.
