Quick pronunciation guide:

Vowels: a = “ah”, i = “ee”, u = “oo”, e = “eh”, o = “oh”.
Mizu is “mee-zoo,” Umi is “oo-mee” and Ame is “ah-meh.”
A line over a vowel (ō, ū) means hold it twice as long, so Yōsuke is “yoh-soo-keh.”
“Tsu” sounds like the “ts” in “cats” plus “oo.”
Give every syllable equal weight, with no heavy English-style stress.
