We would either have to get a translator or learn Japanese. Normally the climate is humid with warm summers and cool winters so i would have to bring more warmer clothes for the winter and more tee shirts for the summer and leave the windows closed for the AC in the summer when it gets hot out. There’s a lot of water around it so i would bring my bathing suits, sunscreen, and boogie board. I would also have to get used to the amount of people there and the large cities meaning i would live a bit farther from the city because i’m not that good in crowded places
