I am Japanese person living in Australia for 11years.
Definitely there is big gap between Japanses taste and western taste of beauty.
Often my friend would point out one of asian girl to tell me Oh she is hot! 80% of time I say she is rather not so pretty.
And when I see pretty asian girl friends would say she is ugly.
So obviously there are different.
I think Japanese go for more cute than beautiful most of time anyway.
And I think miss univers mean is suit for everybodys taste not only for Japanese people.
Some people might think she is ordinaly but certainly she is not ugly at all.
And everybody has different taste.
So so be it.
