Summary
Japan’s English proficiency ranking dropped to 92nd out of 116 countries, the lowest ever recorded.
The decline is attributed to stagnant English proficiency among young people, particularly due to the COVID-19 pandemic.
The Netherlands ranked first, followed by European countries, while the Philippines and Malaysia ranked 22nd and 26th, respectively.
Neither. Japanese has two tones, high and low (for comparison Mandarin has 4 and Cantonese has I think 7), and each vowel/vowel+consonant in a word takes one of these two. For example there are a bunch of words pronounced koukai in Japanese and they’re split 50/50 on whether their tone is high low low low or low high high high, and the words oyster and persimmon (both kaki) are famous for having opposite tones, one low high and the other high low.
By the way Japanese straight up doesn’t have stressed syllables so the idea of a tonic syllable doesn’t really translate to the language.
