The more and more I consume Korean and Japanese content (as I have been ever since I was a child), distinguishing between certain words becomes very troublesome, as these two languages share so many cognates. Both countries' languages are heavily inspired by the traditional Chineseーevident in modern times, as Japanese incorporates Chinese characters with 漢字, and as for Korean, although not used in modern communication, many traces of 한자 still remain, especially in temples and old texts.
Moving forward
I want to dedicate this page to recording all the Korean and Japanese cognates that I encounter, so you can expect this page to be updated quite frequently. I hope that this serves as a valuable resource for those wanting to study both Korean and Japanese. If studied well, you can learn a single word in two different languages. If you happen to find any cognates not listed here, or find any mistakes, please reach out! I would love to hear from you and make this list as accurate and holistic as possible.
