Eating Japanese? I'd say go for it without regrets.
EDIT: Chinese would also be swell, but I'm hopelessly biased.
I eat Japanese food without reservation. I even have my own chopsticks decorated with little zebra cartoons. <3
Soko Gakuen's a teaching program IIRC.
This being said, hmmm... Would probably be worth a shot, at the least? IIRC your job is low-stress, maybe you can grab something that'll let you practice on the job as well.
SG's a language school. 3 hours 1 day a week for 11 weeks in a 10-15 person class. It's really cheap and word has it that it's a good school. Its downside is mainly that it takes a little over an hour to get to via public transportation (and only ~20 minutes by car. sigh.). While annoying, it only means I lose my evening one day a week.
The real question is whether it makes any sense for me to take Japanese. I like it and all, but if I don't end up going to Japan/learning enough to translate things, it's utterly unrelated to everything else I want to do academically since I'm an Anglo-Saxon English major.
* Jo'ou Ranbu knows nothing. >_>
That said, if you are interested in teaching -at all-, I'd say go for it, since it's experience you will want and need if you're thinking of a long-term professor career. Not to mention that it would be a cool thing to have in a resume if that is a program like JET. Gogogo overseas experience and such.
Looking at JET again is what made me start looking into it, honestly. Definitely agree about overseas experience. Teaching only seems natural, especially if I'd be teaching English,
especially if it's in a place I have no earthly reason to have an interest in but do anyway.
