Does this high percentage of people in Japan suffer from this?
Didn't meet 5 people in those 25 years of my life that were allergic to pollen and related stuff. I recon it's because I grew up on village so it's extremely uncommon and for the last 7 years of me living in a city, there's not many people that actually grew up in city, most are like me, from all around. And I'm sure national % is quite a lot higher than % I met.
