Interesting. I noticed that many people have hay fever in Japan, but I always just assumed it was genetic or something. I wonder if living there for a long time will make you more sensitive to pollen

As someone who has suffered from hay fever for my entire life, and also lived in many different locations, almost every move came with a 2-3 year reprieve from my symptoms while my body "discovered" the fun new local allergens.

Hmm, most German forests are also vast monoculture 'tree farms' and have been for the last 250 years (also caused by large scale deforestation in the centuries before). In the Ore Mountains we also have those yellow clouds of pollen coming off spruce trees every few years, covering everything with a thin yellow dust layer, yet I'm not aware that the number of people with pollen allergies is exceptionally high (oth, maybe it was 200 years ago and by now the population has become immune, or maybe the tree pollen in Japan is just more aggressive...).

I got hayfever on my 3rd year of living here, and it seems like quite a common pattern among immigrants I've noticed. I have hayfever back in the UK too, but I guess I didn't have a Cedar allergy - so it took time to develop.

Only two types of tree? Even in the 1970's surely that should have been cause for concern.

This might have something to do with it: > When the sugi and hinoki forests were first planted in the 1950s and 60s, they weren't meant to stand forever. At the time, it was assumed they would be gradually cut down and replanted over time, as had been the case before the war. But as Japan's economy boomed in the late 60s and 70s, major cities like Kobe and Tokyo grew rapidly, and it ended up being cheaper to import w…

I don't get the relevance of "major cities grew rapidly". That can only mean that demand for wood spiked. There's no way it can cause local wood to become less competitive with imported wood.

Germany has half the percentage of forest as Japan

Hayfever allergy rates are growing around the whole world, Germany included.

I'd been wondering why my allergies go nuts every time I visit Japan, but never really suffered in other Asian countries. Cool to know now. Upside is I discovered the trick of just taking fexofenadine every single day which had the side effect of solving my chronic sinus infections.

My quality of life is notably better from daily fexofenadine vs what I think was low-level allergies that I developed in my 20s to pets, dust, etc
