What's a good story without a plot twist. It's like a song without a key change. Totally useless.
So my plot twist is: I will NOT, in fact, be living in Nagasaki but instead be living on an island 100km off the coast of Nagasaki! whaaaat. I'm stoked.
Goto Islands (specifically Fukue, the largest and most populous) will be my actual home for the next year plus. The Goto Islands are subtropical islands known for their white sandy beaches, blue/green water, and a climate wikipedia describes as "oppressively humid". With a population of ~37,000 the island is fully self sufficient, but only a 1.5 hour fast ferry ride away from Nagasaki.
I have been in contact with my JET Predecessor aka the person whose life I am basically taking over. I will be living in his apartment and teaching at the school he was with. This will be one high school I teach in full time, which I am looking forward to since JETs often have to teach at many different schools around a city.
