That’s the tricky part, since in the end it always comes down to every individual, but one thing to always keep in mind is that it needs be fun in the long run. Learning Japanese will take years and speedrunning will only damage yourself and your learning journey so whatever you end up doing, do it in such a fashion that you still enjoy it (bein occasionally frustrated is fine). It is also absolutely fine (and probably necessary) to increase/reduce/add everything mid-journey.
That said, I can share my personal journey and how it evolved over the last 1,5 years:
1. Started with BunPro (about 4 grammar and 10 vocab a day), Wanikani (10-15 items a day).
2. Started listening to a podcast called “Nihongo con Teppei” while joggign to add a bit of listening understanding. Didn’t understand much in the beginning, but the goal was immersion and not complete understanding.
3. After some months the amount of lessons and reviews was a bit much so I reduced it gradually until I came to 2 grammar and 5 vocab on BunPro and 10 items on WaniKani per day.
4. I started using SakuGo, it’s an AI powered app someone developed in beta where you translate sentences from english to japanese using vocab and grammar from a particular N level (N5 for me at the time). This proved to be extremely valuable (but also quite difficult and time consuming in the beginning), since it connected the grammar and vocab for me in a very profound way. Here I started actually understanding the language and how to think in Japanese.
5. Currently I’m on N3 grammar and I decided to switch stuff up a bit and I’m doing 4 grammar points a day and no new vocab, while also focusing more on every individual lesson and review (as in reading every sentence properly, translating words I don’t understand, reviewing grammar which I learned earlier but forgot). The goal here is to finish N3 and N2 grammar, to focus on more vocab afterwards. WaniKani stays at 10 items per day and I don’t plan on changing that.
Basically, I never stopped questioning my approach and changing stuff, sometimes because it was too much and sometimes just to change things up a bit for variety. What I can say for sure are the following 2 points though:
- Never stop doing reviews. Unless you’re physically or mentally incapable, always do your reviews. Pausing lessons is absolutely fine, but having a habit of reviewing every day is what’s going to make the difference.
- WaniKani and BunPro both are invaluable. There is a big overlap in vocab in both, but there were so many words I learned in BunPro first and then just couldn’t remember them for whatever reason, but as soon as they popped up in WaniKani, it sticked (maybe due to nice mnemonics WaniKani provides). Doing both is IMHO very important and helpful.
Hopefully some of this stuff helps!
