I live in Japan and developed an allergy to cedar pollen after I came. I started sublingual immunotherapy (a pill of concentrated pollen you dissolve under your tongue) three years ago and now can make it through the pollen season symptom-free. Supposedly you even keep the immunity after stopping the medication, though I have not tested that yet.

I did sublingual immunotherapy for gramineae and while the immunity does wane with years and in particularly bad years (like this one) you'll get symptoms it's still waaaaay better than before
