Obligatory apology if this isn’t in the right section.
I have an older family member that’s interested in learning Japanese from the ground up (no foundation except reading/watching a lot of manga/anime/dramas), but they’re incredibly busy in their daily life. Ultimately, they want to be able to go to Japan and get around using the language with a decent level of competency.
So I’d like any advice from the community about good starting resources for really busy people. I got them Pimsleur at their request, but for anyone that used similar resources (like Rosetta, Human Japanese, etc), which do you feel worked best? How does Japanese For Busy People compare to just getting them Genki?
