I like learning new words and phrases from N5 単語 1000 book. This tango series have many context sentences examples. I want to put them on Kitsun but doing WK alone is already too much for me. Let alone other SRS I have. Jp’s WK Expansion Pack deck on Kitsun could be an option but without context sentences. Even if there are automatic tango series decks including context sentences, I don’t think I can do all my SRS. I’m Oshin, not Jp. Another option could be reading Japanese tweets or native materials. This one depends on how meow you are. If you’re meow like me, I found reading is still harder than being spoon-fed by tango book series.
They said, practice makes perfect. I practice kanji handwriting too when I have time. But I lack of practice, so my kanji knowledge isn’t perfect, I think.
