The 浪人 or Ronin have no master - The most famous are the 47 ronin created after their Lord committed suicide. This term was not a positive title for the Samurai of ancient Japan. However, in recent years, movies and video games have glorified the term Ronin.
In Chinese, this term has the original meaning of a hobo, vagabond, or ruffian.
In Korean Hanja, these characters would be read as adventurer, wanderer, someone without a steady job, or someone who is wasting away time.
In modern Japan, this term is used as a nickname for a high school student who has failed a college entry exam (and is trying again).
In Chinese and Korean, the Japanese definition of “Masterless Samurai” is known because of the historical context. Even in Japanese, the literal translation is closer to the Chinese and Korean definitions shown above.
This will make a fine wall scroll if you are a fan of the Ronin or see yourself as a Ronin of sorts. However, please think twice before getting a Ronin tattoo!
