Debut is a Chinese word, derived from the French "debut", which originally means debut, and is a special word for singers and actors. In the Japanese music industry, joining the entertainment industry is just considered entry into the industry, and "debut" is based on the official release of a CD.

Many artists or groups have actually acted in TV series, had their own songs, and held concerts before their debut.

Take Johnny & Associates as an example. Undebuted artists are called Jr. (abbreviation of Junior in English), they can only receive a fixed "pocket money" every month, and they can receive corresponding dividends from records, TV series and advertisements after their debut.

For fans, the records released by artists who have not debuted are usually recorded live, with loud noise, and they cannot fully appreciate the idol's voice. There is no doubt that only officially released records can truly satisfy fans. need.
