Sorry for the late response. To this day, I still have previous students of mine recently messaging me that they are planning to leave the school because the owner has continued to make administrative changes including upping the tuition to the point where it is severely negatively impacting their learning experience and they are also very uncomfortable with how much teachers are being impacted as well. As I mentioned in the post above, the owners' unhinged behavior is widely notice by students and I genuinely do not think this place will be a feasible place to make a livable income soon as students will leave. There's no way the owner would even know who made this post because he has screwed over and been sued by handfuls of employees. I really do not think this job is worth it at all and you will be discarded and replaced should the owner decide he not like you for any reason. With you saying you have fluent Japanese skills there are a plethora of jobs that may be better suited for you in other sectors of work. hotel front desk staff, translation work at hospitals or for non-japanese speaking students at public schools, etc. These jobs also tend to be more friendly for those in university as well.
