Hey Toasty! The key is to keep in mind that Every Situation Is Different! My boyfriend is in his first year as a JET CIR working in a government office, which is different than most JETs (who go there not knowing much, if any, Japanese or much about the culture and end up teaching in classrooms)...if you plan on continuing your Japanese Language studies this is a more elite position that could be a wonderful opportunity for you. The program has only been growing, so I imagine that in 5-7 years it will still be a strong establishment of cultural relations
For now, if you find any chance to travel there in the near future...grab it! There are lots of short term summer language exchange camps and other learning/working/cultural opportunities that immerse you in culture while you're there.
Everyone here is very helpful...I've followed the application process and all info seminars since last November...and if you'd like any more info or have questions for a JET who is there currently (I'll get you in contact if you'd like), don't hesitate to contact me!
*KEY* get to know yourself...push your boundaries because so much of the outcome of your experience depends on who you are and how you handle new or challenging situations. A positive outlook is crucial, and while there is a massive support system in place for all JETS, past and present, this advise applies to anything you do in life...but especially if an international lifestyle is your goal
