Keyboard app shares most common emoji by country, Japan's are completely different from others

Kao-moji look like little faces, typically made with parentheses, and they express a huge variety of emotions.
And one such international app, Simeji with over 10 million installs, recently released the top kao-moji usages by country.
Interestingly enough, none of Japan’s kao-moji appear in the top three of any other country.
Also, the “shrugging” kao-moji was the most popular one in 11 countries, but it didn’t even crack the top three for Japan.
It’s similar to how certain “Asian-style” English fonts are completely illegible to Japanese people for the same reason.
