Hey dude, I study Japanese so I know. If you want a life knowing and participate in Japanese culture, JCS is the only good place for you. Bunka is for those who are richer, they actually teach better and faster than JCS, they also organise overseas trips for students to join. Bunka is more for leisure. JCS allows you to have a total and entire course for JLPT 4,3,2,1 within 6 years. If you are going to use Japanese for work, Bunka will be better, cus its real fast. If you want to engross in Japanese Culture, join JCS and slowly enjoy the life of a Japanese. Furthermore, JCS have cultural gatherings for like the Japanese schools and societies of Singapore, you might even get to know rich businessmans from Japan! They are ****ing rich lol. JCS and bunka is more worth your money. I am not joking, the rest is not well-known yet.
