after i learn a new word i aways put them in anki and, for writing practices and better remember the word, i write their kanji multiple times and then i do some exemple sentences with them, and also trying to fit them in the exemple sentences of other words. however, a lot lf times i feel like this isn't enough, and a lot of words (especially the ones that aren't much present in my daily life) can get lost in this ocean of words and i eventually forget them. how do i practice those vocabularies other than using anki?
As a side note, for space repetition you could use Renshuu Instead of anki and have it all integrated.
I would suggest that getting terms wrong in spaced repetition is actually a good thing. It's identifying the terms you need more practice with and will automatically adjust to it. So, trusting the system and doing nothing is a solid option.
But if you want to get in more practice, you could:
Play the Shiritori game here and try to use the vocab there.
Try the crosswords available here. For non Renshuu pro I think they are ~1/month for each of the JLPT levels. But if you upgrade to Renshuu pro you get access to a bunch more, and you can even make personalized crosswords based on your schedules.
