I tried this new app for learning Japanese. It is focused on speaking as each lesson is a brief interactive video where you will often prompted to repeat some phrases or engage in a simulated conversation. The app was originally meant for Korean and it’s relatively new for Japanese, so there are only a few units (each one being about seven lessons) available for the moment, but they seem to be adding more, and even in this initial easy units self learner can practice speaking which is something they might not have had much opportunity to do.
I would definitely recommend giving it a go as it’s possible to use it for free (with the limit of one lesson per day).
