For sufferers of "kafunsho" (pollen allergy), it's hay fever season again.
The past decades have seen more and more people suffer allergic reactions to pollen, especially from Japan's millions of cedar trees. According to the Environment Ministry, cedar pollen levels this spring in eastern Japan will be 1.5 to three times over last year because last summer was hot and sunny. Pollinosis sufferers are desperate for a good remedy.
