This was my first time in Asia. So everything was exciting and new. KCP is a great school which focuses on the language. That maybe sounds obvious, but it's not so much a "good to Japan and have fun" kind of school. If you're looking for that, I'd go elsewhere.
If you'd like you learn Japanese, and meet interesting people, go here. Keep in mind you'll have to make an effort to meet Japanese people, as the school is obviously, filled with non-Japanese.
Recommended if you want to learn Japanese.
