Hello all. I'm new to posting on the forums. I lived in Aomori prefecture when I was younger and didn't have any issues. Two years ago I got a very bad illness and have lung scarring. As a result, I'm on portable O2 and asthma therapies. I'm trying not to let this keep me from pursuing my dream of returning to Japan to teach English. I know Yokohama and Tokyo are pretty bad for asthma sufferers. I've been looking into Osaka and Kobe. Does anyone have any information regarding the air quality there or any recommendations on hospitals/clinics with pulmonary specialists? I've only been able to find ONE on the internet. Any help is greatly appreciated.
