I am a fair speaker of English and mixed Tagalog and Bisaya dialect (Filipino). Learned Japanese for 3 year in high school, my knowledge level is minimal considering the lessons I learned regarding formalities, culture, and how to use the different sets of katakana, hiragana, and kanji writing.
Also in response to the relativity of Chinese and Japanese, I've seen that they use certain similar characters but they are either not the same meaning or different pronunciation.
