It's a very broad term encompassing the entirety of a person's existence, from birth to death. It can also be used in more specific contexts, such as:
* "Jinsei no michi" - The path of life
* "Jinsei no yume" - Dreams of life
The word "jinsei" carries a deeper meaning in Japanese culture than just the literal translation of "life." It often evokes a sense of purpose, meaning, and the journey of self-discovery that unfolds throughout a person's existence.
