For the price we paid, our lessons with Meiji Academy couldn't have been better. Our lessons were taught by native Japanese born and bred in Fukuoka, so not only did they teach us Japanese, but also a lot about their amazing city. The structure of the lessons was easy to follow and meant that it was easy to track our progress, we made a lot of progress!
I guess the whole advantage of doing Japanese lessons in Japan is the fact you get to experience the culture first hand. Outside of our lessons we were able to explore a lot of Fukuoka and the many amazing places in the surrounding Kyushu.
We came with a working holiday visa so our time in Japan has not yet come to an end, but Meiji Academy definitely gave us a good enough introduction to the language to make our stay here a lot more enjoyable.
