Cold is relative, KB. Depends on where you are in Japan and what you are used to. I find the northern reaches of Hokkaido to have rather mild winters, while some people complain about freezing their arses off. Insulation is not always used as one might expect up here, by the way, so it also depends on what kind of housing one has. There is no central heating, though, just a typical space heater.
No, they typically hire uni graduates and on up to about age 40,and even after that there are exceptions.
Then you'd better hope for posting in a warmer area. As for being posted near a beach, same thought holds as mentioned above. Request what you want, but realize that beach areas, bigger cities and Hokkaido/Okinawa are among the more popular requested places.
Those are 2 of the biggest 4 conversation schools (eikaiwa) in Japan. Both went bankrupt, but for different reasons, a few years ago. Their names still stand on signs because the company that took them over wanted customers to feel as if they were still taking classes from the same place.
Uh, no. Not for law school.
You graduated college, right? What do you want to do with that degree and your life? JET and any other sort of international teaching gives someone a chance to experience life and work abroad, little else, unless you really really apply yourself to the local language and business.
