What does “otona” mean in Japanese?
Native speakers say “otona” to mean ‘adult’ in Japanese. Probably, many Japanese learners know this word as it is often used in Japanese conversations. In this blog post, however, I will explain this word in detail based on its kanji expression. And also, I will explain how to use it through example sentences. My explanations would help Japanese learners to understand “otona” more clearly. Then, let’s get started!

Definition and meanings of “otona”
Let me start with the definition and meanings of “otona”.
- otona – 大人 (おとな) : a noun meaning ‘adult’ in Japanese. This can also work as plural. Learn more about Japanese plural. Depending on the situation and context, this can also work like an adjective to mean ‘adult’, ‘mature’, or ‘grown-up’.
Grammatically, this is a noun. Native speakers, however, sometimes use this like an adjective especially in speaking. In the Japanese language, the border between nouns and some adjectives called na-adjectives is very ambiguous. Every na-adjective basically consists of one noun and one conjugative suffix. And native speakers often omit the suffix in conversations. So, Japanese nouns often work like shortened adjectives in speaking. “Otona” is one of them. This is the reason it can work like an adjective to mean ‘adult’, ‘mature’, or ‘grown-up’.
The definition and meanings are not that difficult, I think. To understand this noun more clearly, however, let me explain its kanji characters in detail, one by one.
Otona in kanji
The kanji expression of “otona” consists of the following two characters:
- 大 : a kanji character often used like a prefix to add the meaning of ‘large’ or ‘big’ to its following word. This kanji can also be found in other words like “ōkii“.
- 人 : a kanji character widely used to mean ‘person’ or ‘people’. This kanji character can also be found in other words like “hito“, “koibito“, and “nihonjin“.
From these two kanji characters, we can understand that “otona” literally means a ‘big person’ in Japanese. This literal interpretation is not completely in line with the meanings, but still very close, I think. Adults are often bigger than children.
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 meanings of words they form. Actually, here, we could get the better understanding of “otona” through the detailed kanji check above.
Then, let me explain how to use “otona” through the example sentences below.
Example #1: how to say “adult” in Japanese
kare wa otona ni nat ta – 彼は大人になった (かれはおとなになった)
He became an adult.
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.
- ni – に : a case particle used to say what someone or something becomes after a change or action. In the example, this is used after “otona” to say what “kare” became.
- nat – なっ : one conjugation of the verb, “naru”, which means ‘to become’, ‘to turn’, ‘to get’, or such in Japanese. In the example, it has been conjugated for the better connection with its following word.
- ta – た : an auxiliary verb used after a verb, adjective, or auxiliary verb to make its past tense form. Probably, this is well known as a part of Japanese ta form. In the example, this is used after “nat” to make its past tense form, “nat ta”.
This is a typical usage of “otona”. In this example, it works as a part of the commonly-used expression, “otona ni nat ta”, which means ‘to have become an adult’ in Japanese. This expression should be learnt together with its present tense form, “otona ni naru”, I think.
Example #2: another usage of “otona”
kanojo wa boku yori zutto otona desu – 彼女は僕よりずっと大人です (かのじょはぼくよりずっとおとなです)
She is much more mature than I am.
Below are the new words used in the example sentence.
- kanojo – 彼女 (かのじょ) : a pronoun meaning ‘she’ in Japanese.
- boku – 僕 (ぼく) : a pronoun meaning ‘I’ in Japanese. This is used mainly by boys and young males.
- yori – より : a case particle used to indicate the object on which the comparison in a sentence is based. In the example, this is used after “boku” to indicate the object on which the comparison is based. Word orders in Japanese and English are different, but the role of this case particle is very similar to that of “than”.
- zutto – ずっと : an adverb meaning ‘much’, ‘by far’, or such in Japanese.
- 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 “otona” to make it sound polite.
This is another typical usage of “otona”. In this example, it works as an adjective to say “mature” in Japanese. When we want to say “mature”, “adult”, or “grown-up” in Japanese, this word is a good option.
