Ohayo imtheonlysane1here! I am also trying to self teach some Japanese to assist me on my endeavor to Japan with my school. I myself found Pimsleur: I, II, and III to be very effective. If you feel you are more intermediate to advanced by now, I suggest you attempt to have real sitution conversations with other people who enjoy learning Japanese, or people that are originally from there. Speaking to people whenever you can is very important so you develop a type of muscle memory in your brain. I really hope this helps.
