Quote:
"Miyuzumi" is a transliteration from the Japanese alphabet


What do you mean by "the Japanese alphabet"?

There are two methods of transcribing words in Japanese (which would not usually apply to a Japanese name): katakana (used primarily for foreign words) and hiragana (used for Japanese words where there are no kanji, or Chinese characters).

Mayuzumi's name in Japanese is made up of three kanji, and the first syllable of his last name is pronounced "Ma" (like "mother"), not "Mi" (which would be pronounced in Japanese like "me" in English).

The five M+vowel sounds in Japanese are like this:

Ma = mother
Mi = me
Mu = moo (cow sound)
Me = rhymes with "say"
Mo = mow (cut the grass)
