Personally, I really like Cure Dolly’s subtitled Japanese From Scratch video series.
For text-based learning, you’ll get recommendations on textbooks (such as Genki) and online guides such as Tae Kim’s guide, or Sakubi’s one-page (a long page) grammar guide.
Once you have the basics of grammar down, what will really help is taking the time to try reading native material, even if means deciphering the Japanese text line by line, looking up vocabulary and grammar as you go.
This is harder to do when time is a premium, but it will really help you see which grammar to focus on learning better and it helps you get used to the most common vocabulary words. (We have book clubs that massively streamline this process.)
Plus, deciphering/reading native material (when you’re ready for it, which is sooner than you think) will help your brain’s pattern recognition start to recognize common grammar and vocabulary that you keep seeing over and over again.
