What is the Japanese character for male and female?

There isn't one specific character that represents both "male" and "female" in Japanese. However, there are different ways to express these concepts depending on the context:

For "male":

* 男 (おとこ, otoko): This is the most common character for "male" and literally means "man."

* 男性 (せいせい, seisei): This is a more formal way to say "male" and literally means "male gender."

For "female":

* 女 (おんな, onna): This is the most common character for "female" and literally means "woman."

* 女性 (じょせい, josei): This is a more formal way to say "female" and literally means "female gender."

For "male and female" together:

* 男女 (だんじょ, danjo): This literally means "male and female."

* 夫婦 (ふうふ, fuufu): This refers to a married couple (husband and wife).

* 男女 (りょうせい, ryousei): This means "both genders" in a more formal context.

Ultimately, the best way to express "male" and "female" in Japanese depends on the specific situation and the level of formality required.
