I browsed the internet. Since there were a lot of schools, I couldn't choose the right one for myself for a long time. I got my eye on Meiji Academy since it was the closest to Busan (South Korea).
I was worried about my choice since usually all language schools in Asia are oriented to Chinese/Korean students. But after I arrived, I changed my mind. The teachers were friendly and responsible, the whole program was easy to understand. The majority of teachers could even speak English fluently.
