ジャズ
ジャズ · jazu · JLPT N1 · noun
wind
🎷 ジャズ sounds like 'jazz' itself: 'jazu' rhymes with 'Jazz' (the music), so say 'jazu' the way you'd say 'jazz' in English.
The Japanese word is a direct loanword from English 'jazz', so the sound barely changes. Only the final 'z' gets a vowel: 'ju-zu', not the English 'jazz' with its stop.
