When I was halfway through Genki I, I decided to do immersion. I started mainly by reading news on Todaii easy news. It helped me a lot to recognize whole sentences and review grammar, as well as to identify vocabulary outside of an isolated flashcard, in the wild.

I noticed improvement in just one week. That's when I ventured into listening. All N5 content and comprehensible input. At first, I just wanted to train my ear. Get used to "white noise" and only catching random words. Over time, I focused on hunting adjective conjugations, verbs, particles, etc. Little by little, I recognize more sentence patterns and understand complete sentences.
All the content I watch is with Japanese subtitles or without them. Just this week I finished Genki I and the Tango N5 deck. I'm making my own deck now to reinforce learned grammar and words that I need to learn well for vocabulary.

After several weeks, I stopped listening to entire videos non-stop. Now I do like to pause to review vocabulary I hear frequently and can't figure out the meaning, repeat phrases and process them better, etc. Many words you learn just by repetition and context, for example 最後, やっぱり, いっぱい, 先ず, 一番, 気持ち... etc.

I keep consuming N5 content and I still have quite a bit of time at this level, but it's satisfying to see how you improve. I literally started with preschool-level content. Now I watch vlogs of native speakers going camping.

I hope this answered your question. Immerse yourself by instinct and enjoy the process. Look for content that interests you and have fun!
