The Uchino Sea is a tranquil inner bay located in Naruto City, Tokushima Prefecture. Due to its unique geographical structure as an inner bay, the water remains calm with very little swell, making it an exceptionally stable and ideal environment for raft fishing (ikada-zuri). Currently, approximately 140 dedicated fishing rafts are scattered throughout the area, providing a well-established and bountiful environment for anglers.
The history of the rafts in this area dates back about 50 years to the period when pearl cultivation was highly prosperous. Originally, these rafts were used primarily for pearl farming, but the practice of bringing fishermen onto these cultivation rafts for leisure eventually evolved into the modern raft fishing culture seen today. This leisure activity is deeply rooted in the region's history of aquaculture and maritime industry.

In the Uchino Sea, you can enjoy fishing from numerous rafts scattered across the surface. The rafts are constantly baited by the owners and fishermen, ensuring a consistent environment where fish are easily attracted. Additionally, the scenic view of Kagami-jima—an island that resembles a heart shape when viewed from above—is one of the most notable landmarks in this sea area.

The primary activity in the Uchino Sea is raft fishing. Because the waves are gentle, it is a relatively safe and accessible experience even for beginners or families. However, please note that when using the fishing rafts, you must make a reservation in advance with the specific boat operator/rental service.
Adjacent to the Uchino Sea is the Naruto Uchino Sea General Park. This park features spacious grassy fields and is a great spot for various sports such as tennis, futsal, beach volleyball, and skateboarding. The area also includes a campsite and large playground equipment, making it a perfect destination for a full day of outdoor leisure.
When planning your raft fishing experience, a prior reservation with the boat operator is mandatory. Please prepare your own fishing gear and bait, and dress appropriately for the weather and outdoor conditions. It is highly recommended to contact your chosen boat operator directly for specific details regarding their services and requirements.
