流出（りゅうしゅつ、ryuushutsu）
- leak

The Japanese word 流出 (りゅうしゅつ) primarily means "leak," "outflow," "spillage," or "escape." It describes the act of something, often a liquid, gas, or information, flowing out or being released from a confined space or system. The concept extends beyond physical leakage and can also refer to the disclosure of sensitive data, such as personal information or confidential documents. The meaning varies depending on the context; it can denote the simple act of something leaving a container or the more serious event of a data breach. The term implies a loss or depletion of something. It is a compound word: 流 (ryuu) which means "flow," and 出 (shutsu) which means "to go out" or "to exit," creating the idea of something flowing out.
