The Names in Japanese Originate from Size or Usage
Sorry for the sudden question, but what is each finger of the hand called in your country?
In Japan, they are referred to as:
#1 親指、Oyayubi: ‘Parent Finger’
#2 人差し指、Hitosashiyubi: ‘Pointing Finger’
#3 中指, Nakayubi: ‘Middle Finger’
#4 薬指、 Kusuriyubi: ‘Medicine Finger’
#5 小指, Koyubi: ‘Little Finger’
Why are they named this way?
#1 is the biggest, so it’s called the “Parent” finger.
#5 is the smallest, so it’s called the “Little” finger.
#3 is in the middle, so it’s called the “Middle” finger.
Why is #2 called the “Pointing” finger?
It comes from the fact that you use this finger to ‘point things out’ to other people.
Finger #4’s name is derived from the fact that doctors use this finger when they mix medicine or apply ointment.
