This is a response to questions from nomercyy.
Q1. Is living in suburbs of Japan as expensive as in cities?
It depends on the place you wanna live in.
In general, the residential cost is lower, sometimes significantly lower in suburb than cities. Grocery store usually cost the same, and sometimes higher in surburban areas.
There's one thing you must possess to live in either surburban or rural area.
The car is MUST in those areas, especially in rural areas, because the infrastructure in less populous areas is not as good as big cities.
Q2. Would it be hard to get a job as an English teacher there?
There's always huge demand for native English speakers since English language is virtually mandatory in Japanese schools.
I checked a list of English teaching jobs, and most of the offers seemed to be from big cities such as Nagoya, Osaka and Tokyo. Most of them require university diploma. Some of them require experience in teaching and others do not. All of them pay higher than the companies I've taken job interviews for. LOL.......
If you specify the place you would like to live, I can do further research.
I hope the following websites give you good pieces of information.
