AJALT are the people who publish the Japanese for Busy People books, so if you like those books you might want to investigate their Japanese language classes. After some investigation, I have heard that their classes are good but are geared more toward executive learners. This means that the class size is small and the lessons are provided in smaller doses with less homework.

This might be good if you really don’t have a lot of spare time to go to classes and keep up with study, but I do think more work will yield better results.

Also, people have said that the courses may be a bit expensive, so do check the rates. I don’t have any first-hand experience with these classes, so check them out yourself before signing up.
