If only it was just love that's in the air.  Spring is slowly dawning, and pollen from Japanese cedars is starting to make its way around. Kafunsho (hay fever) season has officially started in Japan. Leftover Valentine chocolates have been pushed aside in convenient stores to make room for kafunsho related items: tissues, surgical masks, mint drops, and more.
Old-timers solemnly stock up their mini pharmacies while the uninitiated examine each sneeze, wondering if this is the year for their own “kafunsho debut”.
“almost hay-fever season” by kalandrakas 
There are numerous statistics on how much of the population suffers from kafunsho – the numbers range from 15-30%, with the percentage being higher in metropolitan areas. The effect of kafunsho on the economy is said to be quite serious: an oft-quoted report  by Dai-ichi Life Research Institute Inc. states that kafunsho pushed down GDP growth rates by 0.6% in 2005. Individual consumption decreases because people try to stay indoors, while lowered ability to concentrate effect labor efficiency.
A week before the Meteorological Agency, on February 13th, announced the blowing of “haru-ichiban”, the first strong southern winds of the year that indicate the ‘official’ arrival of spring, a great many bloggers were watching the beginning of the kafunsho season with trepidation.
A blog post by eternal_name  is a typical example:
