It can be harsh to Anki at first, but you should change Anki settings. I have never used default settings either.
- Separate decks for JP->EN, EN->kana
- Review interval 1 10 240 480 (10 min, 4 hr, 8 hr)
- Not too many review cards per day. I limit this to 50 review cards per day
- At most 10 new cards per day, if it is too hard.
- Create your own mnemonic, and type the mnemonic in the card
- Textbox, to replicate WaniKani style {{type:field}}
Or, rather, upload this to Memrise. I can’t successfully do that.
