I totally agree with you on context. Something that has worked for me is to add the Core10k(http://rtkwiki.koohii.com/wiki/Core_10k and the Core6k decks to Anki and then when I bump into a new word I want to learn, I search for it on these decks and move the corresponding cards to my main study deck. These decks have the words in the context of one whole sentence including audio and images. Also, I only add words to my main study deck that I have seen in a real Japanese text.
That is not enough though and that problem you are describing is the reason I am developing Koipun Reader(https://www.koipun.com/reader/). My goal for Koipun Reader is to help intermediate level learners go through any arbitrary Japanese text and give them the ability to save words they want to learn, so that they can review them later within the same context of the text they read. I only have preview version of the app right now, but I will release an MVP in a month.
