意味

Please share/retweet/spread the word — a request to help information reach a wider audience on social media.

拡散希望 (kakusan kibō) literally means 'spreading desired' and is the Japanese equivalent of 'please RT' or 'please share.' It is added to posts when the author wants the information to reach as many people as possible. Commonly used for missing person alerts, event promotions, important announcements, and sometimes just self-promotion. While it is effective, overuse can be seen as attention-seeking. Some users abbreviate it to just 拡散. The phrase became iconic on Twitter/X Japan and is now used across all social platforms.

例文

1. 迷子の猫を探しています。拡散希望です。
