It really depends how you study. If you study by pre-reading, then reading while listening to content on LingQ, you will develop your listening skills at the same time. Then if you listen to those same lessons while doing your chores and walking, you also develop your listening skills. I recommend you work on both your reading and listening.
At one million words read in Italian, I had the following LingQ stats:
known words 9,532
LingQs 27,049
LingQs learnt 6,096
hours listened 274
hours of speaking 12
Around this level, I started watching Pokemon and understood enough to enjoy it (I was already familiar with the story though).
Japanese might count words differently than in script-based languages, I’m not sure.
But for me, based on how I studied, at one million words read, I wasn’t very good. I had already passed an online B1 comprehension exam, but at this level, I was still very limited in what I could do. Really, for me, my competence in Italian came much after. Based on my study practice, my language, my circumstances, by the time I reached Intermediate 2 on LingQ, I was competent to enjoy most things in Italian (podcasts, TV series, movies, conversing with people, but not books). It just takes time.
