大学デビュー

• 読み: だいがくデビュー
• ローマ字: daigaku debyū
• 漢字の分解: 大学 (university) + デビュー (debut, from French) → university debut / fresh-start reinvention
• 発音: /da.i.ga.kɯ.de.bjɯː/

意味

Reinventing yourself when starting university — changing your appearance, personality, or social status to escape your high school image.

大学デビュー is the phenomenon of students dramatically changing their image upon entering university, where nobody knows their past. Common transformations include dyeing hair, adopting trendy fashion, becoming more outgoing, or joining popular social circles. While sometimes successful, a failed 大学デビュー — where the transformation is too obvious or forced — becomes a source of secondhand embarrassment. The concept reflects the intense social pressure in Japanese high schools and the fresh-start opportunity university represents.

例文
