Pronunciation of Japanese Vowels
Fortunately for non-Japanese speakers, Japanese vowels are pronounced with reasonable consistency. Whereas vowels in English and many other languages often have more than one pronunciation (for example, the "a" in ball, bat, and cake), Japanese vowels are pronounced essentially the same in every usage, as shown in the table below:
Vowel Written in Hiragana/Katakana | Written in Rōmaji | Pronunciation (Nearest English Equivalent) | |
あ ア | a | "ah" as in "all" | |
い イ | i | "ee" as in "eel" | |
う ウ | u | "oo" as in "pool" | |
え エ | e | "eh" as in "egg" | |
お オ | o | "oh" as in "old" | |
