Peaceful or calm
Kazen is a modern name likely derived from the Japanese word 'kaze', meaning wind, or potentially as a creative variation of Caden or Kasen. In a Japanese context, when using specific kanji, it can also relate to concepts of peace or gradual change. It has gained some traction in the US as a unique, rhythmic choice for parents seeking a contemporary sound.
