Definition and meaning of “ouji”
Let me start with the definition and meaning of “ouji”.
- ouji – 王子 (おうじ) : a noun meaning ‘prince’ in Japanese. This can also work as plural. Learn more about Japanese plural.
Native speakers use this noun to refer to a son or sons of a king. So, this can work in more or less the same way as the English noun, “prince”, does.
The definition and meaning are simple and clear. To understand this noun more clearly, however, let me explain its kanji characters in detail, one by one.
What does “ouji” literally mean in Japanese?
The kanji expression of “ouji” consists of the following two kanji characters:
- 王 : a kanji character used to mean ‘king’ in Japanese. This can also be found in other words like “ousama“.
- 子 : a kanji character used to mean ‘child’ or ‘kid’ in Japanese.
These two kanji characters tell us that “ouji” literally means a ‘king child’ in Japanese. This literal interpretation is very close to the actual meaning.

When we meet new kanji expressions, we should check their kanji characters in detail to understand their meanings clearly and deeply. In many cases, kanji characters tell us a lot about the meanings of the expressions they form. Actually, here, we could get the better understanding of “ouji” through the detailed kanji check above.
So far, I’ve explained the definition and meaning of “ouji” together with its kanji characters. Then, let me explain how to use it through the example sentences below.
Example #1: how to say “prince” in Japanese
kare wa kono kuni no ouji desu – 彼はこの国の王子です (かれはこのくにのおうじです)
He is the prince of this country.
Below are the new words used in the example sentence.
- kare – 彼 (かれ) : a pronoun meaning ‘he’ in Japanese.
- wa – は : a binding particle working as a case marker or topic marker. In the example, this works after “kare” to make the subject in the sentence.
- kono – この : a determiner used before a noun which refers to something close to the speaker. In the example, this is used before “kuni” to say “this country” in Japanese.
- kuni – 国 (くに) : a noun meaning ‘county’ in Japanese. This can also work as plural.
- no – の : a case particle joining two nouns or noun equivalent words. Normally, the first one can work as a modifier to describe the second. In the example, this works to join “kono kuni” and “ouji”. The formed phrase literally means ‘a prince of this country’ in Japanese. Word orders in Japanese and English are different, but the role of this case particle is very similar to that of the English preposition, “of”.
- desu – です : an auxiliary verb used after a noun or adjective to make it polite. Probably, this is well known as a part of Japanese desu form. In the example, this is used after the noun phrase, “kono kuni no ouji”, to make it sound polite.
This is a typical usage of “ouji”. In this example, it works as a part of the noun phrase, “kono kuni no ouji”, which means ‘the prince of this country’ in Japanese.
Example #2: another usage of “ouji”
ouji wa mada totemo wakai – 王子はまだとても若い (おうじはまだとてもわかい)
The prince is still very young.
Below are the new words used in the example sentence.
- mada – まだ : an adverb meaning ‘still’ or such in Japanese.
- totemo – とても : an adverb of degree meaning ‘very’, ‘much’, or such in Japanese. In the example, this works in front of “wakai” to emphasize its meaning.
- wakai – 若い (わかい) : an i-adjective meaning ‘young’ in Japanese.
This is another typical usage of “ouji”. In this example, it works together with the binding particle, “wa”, to become the subject in the sentence. Anyway, when we want to refer to a son or sons of a king in Japanese, this noun is always a very good option.
