The “Irodori” free online course will resolve the issue you have, one of the perfect e-learning courses for Nihongo self-study learners who want to focus on listening and speaking before anything. You can have romaji on up to Lesson 10 or halfway through the A1 course. You can buy some time to master all the kana. The learning content is as challenging as Genki as it’s designed for learners in Japan. https://www.irodori-online.jpf.go.jp/ Japanese Communication Marugoto HCMC Tp.HCM Vietnam
