Whoa, that was fast. Congratulations on your good progress.
Hat off to your point 2 especially. Taking the time to write longer texts is excellent, but it can also be really draining. Letting it be checked by AI I think is actually a good use of the technology! It will make some minor mistakes (being good most of the time). These mistakes won’t matter in the long run! The actual learning happened by using the curated textbooks.
The step to native material will be hard at first. Even after having finished Genki II. I suspect you will mostly be held up by vocabulary at the moment, since there’s just a physical limit on the amount of vocabulary you can learn in this short time frame.
Alternatively try the free stories from https://www.satorireader.com/ as a stop gap to transition to native material, maybe 1-2 weeks to get the hang of more complex sentences?
Possibly add a setup to mine some words into Anki cards. Don’t go too hard on the mining. Adding ~10 words a day should probably be a nice goal. Immersion > flashcards
Be clear about what you want to achieve in each session. Going into a session with the goal of 100% comprehension and dissecting the text is good. Going with the flow of the story and living with only understanding 80% is also good. Vary between these styles but be clear on which one it is before starting each time.
You are honestly going at such a fast pace that I’m not sure my advice is appropriate for you :X.
If you maybe have a rough outline of what you want to achieve in the next 2-3 weeks I can give some additional feedback on that. Otherwise, I can only wish you good luck!
I went through all of your links and for now choosing a fairly easy novel or manga from natively seems like a most obvious thing to do. Also, huge thanks for pointing out in-browser manga and book readers with yomitan words lookup. They will come in really handy since I have the whole anki and yomitan thing already set up.
One thing I’m not sure about is how should I approach the listening. The most accessible thing I can think about is games (like VNs) with voice acting from the spreadsheet you linked.
Also, by:
do you mean I have to fully understand each word and what every grammar is doing? I predict some really heavy decyphering, though, it’s not like I’m that much against it.
Yeah, reading and listening kinda diverged at this stage in my learning. It can be really effective to have the text you read in audio format as well. It’s just not always that easy.
Things that come to mind:
VNs with voice acting
Audiobooks for books (pricey)
Anime for Manga (not 100% the same)
朗読(reading aloud) for tales
Let’s play channels for games, which read the text out loud + commentary
But you have to decide if you want to limit your reading to having audio or not. Personally I do both semi-independently. Generally YouTube can be quite good since subtitles (sometimes partial ones) are pretty common in Japanese YouTube, and they can help you to confirm your listening is picking up the correct words.
If you are not against material from natives especially for learners there’s also a plethora of podcasts that can be great, often with a transcript available as well. (you can take a look through The Ultimate Additional Japanese Resources List! for example)
It’s hard to give concrete recommendations since you are now in the long stretch of engaging with material without a 100% clear path forward. There are multiple ways to choose from. Since it is such a long path it is real important to choose something that you enjoy. If that is watching Anime, listening to podcasts during commute or playing VNs I can’t say ^^.
Depending on your learning style it can be beneficial to sometimes take a step back and actually think about what each part of the sentence is doing. Why is there this ん in the sentence? Does the sentence ender わ convey important information (can men use it too?). Why is the sentence in passive?
It also helps you to unearth some new grammar sometimes.
It’s certainly not something you should do every time you engage with Japanese.
But like I said, I just throw out recommendations in all directions since I don’t have a good grasp of what you actually need. You only can find that out yourself by seeing what you like and how you are actually making progress.
As an example: You worked well with the Genki Textbook and seem to have gotten quite a benefit from them. On the other hand I know a sizable amount of people that don’t like learning from a Textbook at all and found it way too boring.
