Japanese has a rather complex writing system that features kanji characters from China. There are also native writing systems called hiragana and katakana that are used along with kanji in written Japanese.
The latest Hanzo skin features the characters 矢印 (yajirushi) on the strip of his quiver. When Japanese people see this, it stands out like so:

Why? Because yajirushi literally means "arrow mark", as in the arrow symbol you'd see on a sign or a map. It doesn't mean "arrow" as in the thing you shoot from a bow -- that would simply be "ya" (矢).
So seeing the word for "arrow sign" on Hanzo's strap looks so weird to those who know Japanese.

If you are wondering how this happened, Google Translate could be the culprit. If you put "ya" (矢), you get "arrow" in English.
But, if you put "arrow" in English, you get "yajirushi" (矢印), the word for "arrow sign".
If you put in "yajirushi" (矢印) in Japanese, you do get "arrow", but the more accurate, though somewhat awkward sounding "directing arrow" below.
The inclusion of this kanji is miffing Overwatch fans in Japan.

"Even though I thought why has Hanzo been turned into those odd [kanji] T-shirts foreigners wear... Is it that 'ya' (矢) is 'arrow' and 'arrow' is 'yajirushi' (矢印)? lol"
