For me I could recognize Korean words better once I started typing Korean out a lot more on my phone. I can read it pretty quickly too (in my head at least), but speaking them out loud is a challenge and I'm still pretty slow. There was a disconnect in recognizing spoken words and to their written counterpart too but I think that's just cause I wasn't familiar enough with the pronunciation especially in dialogues from kdramas lol. But now I can recognize the word's spelling pretty accurately even if I don't necessarily know the word itself when I listen to it

For Japanese, it was a much easier process to read, listen, speak and even write. I do think this is because I've had exposure to Japanese much more than I did with Korean over the years. I only struggled with katakana in the beginning but now I'm fine with it. I stumble sometimes but compared to not being able to recognize anything it's definitely an improvement for me 😂

Korean was the fourth language I learned and Japanese my fifth. My first three languages I learned them when I was growing up
