>>6187262Anki is just one tool in order to help you memorize. There are others useful tools. With just Anki you won't be able to actually understand and speak Japanese.
Vocabulary, grammar, and listening experience are more important than grinding Anki alone. Anki is good for learning general and basic meanings of the most common kanji, but to actually learn Japanese language and even words and expressions alone it's not a good tool. You'll miss out a lot of nuance and alternative meanings and ways to use words by just grinding Anki or some other kanji learning app.
From my personal experience, living there for some years helped tons. Also make sure to actually consume Japanese medias, like for example books and novels. If you're willing to read everyday, you will not be in need for Anki a lot. Just lightly reading/reviewing words, listening a native Japanese pronouncing them, and reading one or two sentences when those words are used is more than enough to give you a good foundation to speak Japanese after.
TL;DR: You should probably use Anki to get started and learn the first 2000 kanji or so. Read everyday and watch variety shows, news or youtubers to listen to native Japanese (movies and dramas have theatrical style of speaking so I don't recommend relying on them a lot).
