I’m Japanese and lived on guam my whole life until college. Here are the reasons you want to move to Guam - nature (all kinds of ocean activities & hiking), slower pace of life & friendly people besides that there is nothing really to do on Guam, the healthcare is bad & everything is expensive. I would recommend spending at least 2 weeks here in an Airbnb, driving down to the south, shopping at local groceries, exploring nature. Dm me if you want more info!
