So Young, So Bright (ジャンケン娘, Janken musume) (literally, "Rock, Paper and Scissors Girls") is a 1955 color (Eastmancolor) Japanese musical film, directed by Toshio Sugie.

This is the first of the so-called "three girl" (sannin musume) series of films produced by Tōhō Studio, which involved teaming three popular young female stars of the period, employing a plot that portrayed their characters as best friends and recounted their romances and other adventures.

Hinagiku wants to meet a young male student named Saitō Matabei, who he met twice in a tatami room in Kyoto before welcoming a man she doesn't like as his husband.

On the other hand, Saito, who learned about the circumstances of Hinagiku, consulted with his father, a businessman, and got money to help him free.

After finishing the dance, Ruri calls Kitajima his father for the first time and reunites without being particular about the history of their past.
