Hatsu is a term used in various contexts, primarily in Japanese culture. In the context of Japanese New Year, it refers to the first occurrence of something in the new year, such as the first sunrise or the first shopping day. It symbolizes new beginnings and fresh starts. In the realm of martial arts, particularly in karate, Hatsu can refer to the initial movement or technique executed in a sequence. This emphasizes the importance of starting strong and setting the tone for the rest of the performance or match.
