You only get out what you put in!

The course is definitely as challenging as everyone is making it out to be.
All classes are completely in Japanese and your classmates are mainly from other Asian countries so you're in a place where you've got to use everything you've got at your disposal. This makes it challenging, but you'll quickly find yourself understanding more and more through the immersion offered.
There is English support available should you need it and the supplementary classes and clubs available have a lot tailored to what you may be keen on.
The school events including school-wide bbq and the American program weekend trip were especially great to spend time with fellow classmates and learn more about the local culture here in Japan.
The workload is high, but try not to get too discouraged, what you'll learn is very useful for your Japanese goals.
