Hi,
I'm (hopefully) going to study master degree in Osaka university next April. I'm currently studying JLPT 1, but I'm not that confident with my skill. I'm dreadful if I can't understand anything in the lecture.

So I thought I'll do a short course before the university start next year. I'm thinking of going to Yamasa, as people suggested. But since it might be troublesome to move cities in short period of time, I'm trying to find one in Osaka.

I found only this school (HAJL) has the short term advance course. Does anyone has experience in that school? Or has any other recommendation in Osaka?

Thanks.
