Did you know?
- While 10代 describes a person's age, the same character 代 is used to count the succession of emperors or shoguns. This frames a human decade as a mini-era or dynasty within a single lifetime.
- In Japanese pop culture, 10代 is often linked to the word 青春 'blue spring'. Together, they evoke a romanticized, fleeting period of emotional growth common in 'shonen' and 'shojo' manga.
- The character 代 also means 'substitution' or 'proxy'. Because of this, the same character used in 10代 appears in words for 'representative' or 'substitute', linking the idea of a generation to a placeholder in time.
