JET Programme was the single greatest adventure of my life! I taught in three high schools in Hiroshima for three years. My placement was perfect for me! Not only was the support network great, but my colleagues became a part of my extended family.
I was lucky to live in the suburbs, have my base school in a rural community (the "inaka") and have two visit schools in the big city. This afforded me a chance to experience the different lifestyles Japan has to offer. My base school was small, but I came to know each of my students (plus their families) and integrated into the local community. Their triumphs became my triumphs; their tears, mine. There is nothing better than joining your school and community in cheering your students all the way through their summer baseball tournament and joining them at the Koushien.
The compensation was great, but the memories were better. I HIGHLY recommend the JET Program for anyone looking for a "home away from home" in Japan.
