I started reading a lot after level 30, but I had a bit of a unique situation happen haha . Basically, I was near level 30 and almost done with book one of Minna no Nihongo (so I was above N5 but not yet at N4 in terms of grammar ability) when my favorite pro wrestling translator left the two companies he was translating for, including my favorite company, and they did not replace him (one of them has since gotten a new translator, but the other still hasn’t).
So I ended up sort of taking over, or at least trying my best to. I started translating backstage comments and such from the show recaps, despite having nowhere close to the level of skill I needed to be doing such a thing. But it was either I do it myself or no one does it, and I wasn’t ready to give up on all of these characters and storylines that I’d gotten invested in.
It has been ten months now since I became a fan translator, and well, I’ve gotten a lot better at Japanese, and a lot better at translation! I’m also much quicker than I was at the beginning, and I make less mistakes because my vocab and grammar and reading speed are all so much better. I probably spend about the same amount of time on my translations, but I just am able to translate more text now than I was before.
So, short answer, yes, I started doing a lot more reading after reaching level 30 . I’m not sure exactly how much, but I’ve spent at least several hours on it pretty much every single week for the past year. I haven’t slowed my WK pace at all, though. I just added the wrestling translations (and then additional Anki time after I started mining words from the wrestling stuff I was translating) on top of the time I was already spending on WK and my textbook.
I’m planning at finishing WK at more or less the same pace I’ve been going for the past year and a half, which is about two weeks a level. I’ve also kept up my same pace with my textbook. I didn’t want to mess with the habits I’d already established, and I think this was a really good idea.
I do see the light at the end of the tunnel coming up with WK, though (not that I experience much strain from it, the pace I’m going at ). I should be reaching level 60 early next year, and from that point, my WK time is going to taper off. But I probably will be putting that extra time into the other hobbies I’ve been neglecting in favor of Japanese instead of reinvesting that WK time into immersion.
