Eikaiwa is the Japanese word for English conversation, even though many/most people use it as the name for the school that helps teach such.
In eikaiwa schools, teachers have classes of 2-10 students of varying ages. They spend 45-90 minutes (depending on the school) going over grammar points that were usually taught in junior and senior high.
...
Ideally, such places serve to review the grammar in a casual, friendly, useful way and give students time to talk about 80% of the period. In reality, things are a gray area.
Hence, me wondering the name..
How about "英文法". Sounds like it would be more appropriate.

Thanks for the explanation Glenski! That was pretty much what I thought it would be.
I once attended this really great English conversation class here in Finland. We would gather into a comfortable, cozy, little room and each time someone would bring a subject we would discuss. A newspaper article or something like that, that we would read before the conversation.
Then after an hour or so of discussion the teacher would correct some mistakes that were made frequently and give some hints for how to speak more naturally. This would take up to 10 or 15 minutes.
It was a really great format and I learned a lot! True "英会話"
I disagree. Many people, including myself, are immersed with girlfriends/boyfriends/spouses who can't or won't teach. Being "immersed" if you teach English in Japan is a horrible way to learn Japanese. You are always "on" during work, and are prohibited from using Japanese in the classroom. Many teachers hang out only with native English speaking friends who don't care to learn the language and who put peer pressure on you to go out with them (and speak only English, often to bad-mouth the school or country).
I will have to say that I believe strongly in immersion being the single best thing for language studies although that requires actually getting "immersed" to an environment in which you have to use the language to survive..
I thought I could speak Japanese when I went to Japan
(I had been studying it by myself for about three years) but noticed soon how dead wrong I was. After three months of daily having to use it to get the simpliest things done, I could truly say that I could make myself understood in Japanese.
It was not perfect but I could ask for directions, have some sort of conversations with people, etc. I truly learned more in those three months than in the previous three years and even that short stay really gave a boost to my studies.
It takes self-discipline, not immersion or an intimate friend, to learn the language.
I do agree 110% in that it takes self-dicipline!
I learned basics of English in school, but I really started understanding it when I began to read books, watch stuff in TV, play computer games, chat in the internet, and talk with people in English.
Using it to do all kinds of fun stuff was what really teached me and the same goes for Japanese too.
To reach the point where doing "fun stuff" stops being a burden and actually becomes fun is where some serious dedication and self discipline is needed but there too some real immersion can make it a great deal easier.
Btw. If you learn from your spouse, don't you just end up speakin the wrong way..? I.e. a guy speaking like a girl.
So no luck there..
