Kanji and meanings of Inosuke’s name
Hi, it’s Junko from Japan. In this post, I’ll explain what Inosuke’s full name means in Japanese.
First Name INOSUKE

I = I sound
NO = of
SUKE = help, suffix for boys’ names
Honestly, the Kanji characters of Inosuke’s name don’t have particular meanings. They’re all used to represent the sound. I think Inosuke’s name comes from the word INOSHISHI, meaning “boar” in Japanese.
The last symbol SUKE used to be a common suffix for Japanese boys’ names. Also, it’s sometimes used to emphasize someone’s features. For example, CHIBISUKE stands for “little guy.” CHIBI is slang for “small” and we use it as “shrimp” in English.
As you know, Inosuke is a boar boy and that’s why he was named INOSUKE. For your information, his favorite phrase CHOTOTSU MOSHIN (head-long rush) originally means “rush like a boar.”
Last Name HASHIBIRA

HASHI = a beak of a bird
BIRA = flat
It’s a super-duper rare name. Literally, HASHIBIRA translates as “flat beak.” In Japanese, neither the word nor the last name exist, and the author Gotouge Koyoharu admitted it’s his creation.

So he is a helpful duck? Since flat beaks are bills, which belong to waterfowl like ducks and geese. Or is that too cute?
If you read the kanji letters literally, it might be so, haha. Some Japanese fans guess that Inosuke’s family name come from Garuda, the king of birds. Though only Mr. Gotoge knows the truth!
