Flexible in Chinese / Japanese...

This 柔 Kanji literally means flexible, pliable, gentle, or yielding.

柔 is also the first Kanji of the Japanese martial arts titles of Judo and Jujutsu (Jujitsu). In those cases, it's pronounced "ju" in Japanese. However, alone, the classic pronunciation is "yawara". Some translate this Kanji (in the context of martial arts) as "The Heart of Judo".

Please note that this just means pliable, gentle, and yielding in Chinese and old Korean Hanja. They do know what Judo and Jujitsu are but if this character is seen alone in China or Korea, people generally will not think of the martial arts context.
