There are about 10 Hyogo BoE placements in the city. 1 JET is farther north in the city while the rest live in (or near) an area called Rainbow Town in the southern part of the city. You will know this area instantly the moment you approach because there will be towering rainbow buildings ahead of you. Some of the ALTs have base schools in the city while others teach in either Ashiya or Amagasaki.
