AH OK, I didn't see that! thanks !

Well Miki is a Japanese name, but I am 100% certain that she is not Japanese. She won't be korean either, as a korean girl would not chose a japanese name as her nickname.

If you have lived long enough in asia, you will know that Chinese, Hongkong Chinese, Taiwanese will use a "foreign name" and their real name.
I met so many chinese and they said "My name is Peter" after asking them Peter? they told me their real name, which was unpronounceable.

So reading and analyzing her travel pattern, I would assume that she is not Vietnamese nor Hongkong Chinese. A Hongkong Chinese would not go to a Michelin Star Restaurant, but to a more local restaurant.

From her skin color I would rule out Thailand, Vietnam and Kambodcha.

I would guess that she is Taiwanese or Chinese (probably Taiwanese).
Taiwan would fit, as Taiwanese are real foodies.

Btw. from her clothes and seing a wedding ring on her hand, I would guess that Mibenkito is between 28-35 years old. ...

I am not sure if I am right, but I just wanted to show you, that giving up too much information in your blogpost will eventually expose your real identity. Someone with better analytical skills than mine, and if mibenkito posted another 50 blog posts, going through them, I am sure her nationaly will be exposed at one point...
