Pros: self training for future stressful situation, meet new people, enjoy smallest joy in life, eat japanese food.
Cons: it is a business not education.
A typical day starts around noon, and ends around 9 or little later.
Work experience differs based on the assigned school. Most of the co-workers are mainly either "really in love with Japan and it's culture" – more... or "used to have the first statement but now depressed".
"Teaching" part is really easy, as long as you can follow the structure and be an entertainer. *Unless you have "one on one lessons" with a particular student, do not expect them to improve dramatically. Even with the lessons it is hit or miss.*
This job requires patients, a lot of patients.
It is like if you care about "teaching" you may suffer, if you can say this is not "education" it is a "business" you may survive. – less
