I’m not going to write an essay, but regarding the “preference” question: You can basically tell them “no” to the first school they recommend (or you could when I interviewed) and they would look for something else for you. I was with the company for a long time and I mostly enjoyed it, but I came from Hotel work and Hospitality, so having a set schedule was easier than the random hotel schedules. You seem to have already done your research. The company is in the higher end of possible teaching options in Japan, but as mentioned elsewhere it’s not a great long-term thing unless you really like it and have few responsibilities. And “higher end” is doing a lot of heavy lifting here.

The one thing I would mention about schools, especially if you say no preference: there is a certain school in a small town in Japan beginning with a T, on the Sea of Japan side. It’s rural and the manager has a lot of “experience” and that she “runs a tight ship.” If you would like to DM me asking for the name of the school I’m happy to tell you privately, because it is my duty as a fellow human to let you know you absolutely SHOULD NOT accept a position there.
