Both Asahi and Yixian have Japanese training. The biggest difference is that Asahi is a professional Japanese training, which is more professional! Yixian has many comprehensive analogies, accounting, network, software and textual research. If you want to learn these things, I can recommend Yi Xian to you. If you want to learn Japanese well and reach N2 level, you'd better study in Asahi. I have also learned about Yixian, and Japanese is basically the foundation. As far as the price is concerned, it is not cheap just for Japan's N5 level, and Asahi's reputation is also good.
