Shiri ga Aoi (A Blue Hip)

Today, I will talk about the Japanese idiom "shiri ga aoi."

The literal meaning is "your hip is blue," but it actually means that someone is premature or young.

This comes from that infant hips are bluish.

The blue hip is called "moukohan" (Mongolian blue spot), and is often observed in Asian.

In particular, it is said that more than 90% of Japanese infants have the moukohan.

It's thought that the generation mechanism of the moukohan is related to pigment called "melanocytes".

Also, there is another idiom "kuchibashi ga kiiroi" (your beak is yellow), which have the same meaning of "shiri ga aoi."

This comes from that a baby bird have a yellow beak.

I think that this idiom is similar to "green horn" in English.

幼児の青いお尻は「蒙古斑」と呼ばれ、アジア人に多く見られます。

特に日本人の場合、9割以上の新生児に蒙古斑が見られるそうです。

蒙古斑ができる理由はメラノサイトという色素が関係していると考えられています。
