How do names work in Japan

Curious how Japanese names work? Well, read further to know more about how names and surnames are decided for a person in Japan. 

If you’ve any Japanese friends or acquaintances, I’m sure you must have wondered about their name. It sounds mysterious and follows a pattern, right?

How Japanese names work?

Japanese names typically come after the surname, unlike the western countries. Example: If the name is Suniyo and the surname is Yamamoto, it’d be written as Yamamoto Suniyo. The people are mostly referred to with their surnames or their titles. The Japanese name for males consists of Kanji characters whereas female names are popularly written in Hiragana or Katakana. The surname consists of one or two Kanji letters.

That’s right. Japanese names consist of two parts, surname and the actual name. Unlike in the west, surnames in Japanese come before the actual name. 

Keeping a middle name in Japan is not much of a trend. Japanese names are written in three different characters, Kanji (originated in China), Hiragana and Katakana (both originated in Japan).

I have many Japanese friends and I was initially confused about the origins of their names until a friend of mine explained it to me in detail. I later went back and read several books on Japanese names to quench my curiosity. 

Anyway, without further ado, let’s move on to explain to you how Japanese names work in detail.

How Japanese Names Work


Let’s begin with how Japanese names work and then move forward to surnames and titles. 

Like I said earlier, names in Japanese come after their surname. People are usually referred with their surname except for children, that’s how Japanese names work. 

For example: If the name is Shinnosuke and the surname is Nohara, it’d be written as Nohara Shinnosuke in Japanese. Surnames are usually taken from father but it changes to their husbands once they’re married off to a different family. 

This tradition is prevalent in many Asian countries like Korea, China etc. The names are written in Kanji but sometimes women may have a few name parts in Hiragana or Katakana.

Japanese names are difficult to read and pronounce which is why while filling forms have a phonetic guide the person has to mention called furigana. Japanese politicians often have their names in Hiragana or Katakana because they are easier to read than Kanji.

The names are also regulated in Japan. One person was questioned when they kept their son’s name as Akuma which means demon in Kanji.
