A surfboard may look like a simple tool made of urethane foam coated with plastic, but it is packed with a history of wisdom and ingenuity. While paying respect to the culture built up by our predecessors, we are exploring new possibilities for surfboards.

Based on our belief that "beautiful things are functional," we named our brand Curvaceous Surfboards, which reflects the beauty of curves.

Our goal is to create surfboards that make your heart leap when you hold them in your hand, when you paddle out, and when you catch a wave.
