虎穴に入らずんば虎子を得ず
koketsu ni irazunba koji o ezu
Need a push to be brave? This proverb is the one: koketsu ni irazunba koji o ezu (虎穴に入らずんば虎子を得ず).
I’m Arasen, an elementary school principal and calligrapher in Japan. It comes from an ancient Chinese general – and in our skit, from a boy trying to talk to the girl he likes!

A Word from Arasen
“If you don’t have the courage to take a risk, you won’t win big!” – this proverb pushes you forward.
Koketsu is a cave where a tiger lives. Koji is a tiger’s cub.
It says: if you want the tiger’s cub, you have to go into the dangerous cave. Pretty scary!
It comes from old China, where these words were said to frightened soldiers: “Find your courage!” And they won.
(Translated from Arasen’s original Japanese.)
