Do you notice that all japanese names end with a vowel?

Question

or 99.9% of them. i also notice this in italian names.

Answer 1

All Japanese words end in a vowel, or the letter n:

Tokyo
Hirohito
Misubishi
Nippon

In fact, all Japanese words can be broken up into syllables, each of which ends in either a vowel or the letter n.

To-kyo
Hi-ro-hi-to
Mi-tsu-bi-shi
Ni-ppon

It's a feature of the language.

Answer 2

thats cuz the japanese script (katakana) has letters like that..
the letters are basically :
a i u e o
ka ki ku ke ko and so on
the few that dont end with a vowel are n(pronounced nuh)
and since the names are formed of these letters they basically end with vowels (like a majority of the letters)

Answer 3

Nope, interesting observation!

Answer 4

thats true with one exception: words may end with the letter "n"
