Kamogawa Maiwai Zome is a traditional celebratory dyeing craft from the Boso Peninsula, rooted in Edo-period fishing culture. Originally called manjuwai, meaning a celebration of an extraordinary catch, the term came to refer to festive garments worn on special occasions by fishermen. Distinct from simple large-catch towels, these elaborately dyed outfits featured over 200 auspicious and sea-themed designs—such as cranes, treasure ships, Ebisu and Daikoku, and dragons. The dyeing technique, known as Manju-zome, has been passed down through generations of the Suzuki family in Kamogawa. Designs are typically split between the back, often featuring ship names and crests, and the waist, which depicts lively scenes tied to fishing and folklore.
