Overview (history, characteristics, attractions)
Kashiwajima is a small island (connected to the mainland) in Otsuki Town, Hata District, Kochi Prefecture, and a tourist destination in southwestern Shikoku known for its beautiful sea and rich ecosystem. With its crystal clear emerald green waters, colorful coral, and tropical fish, it is popular nationwide as a diving and snorkeling spot. The island itself is dotted with small settlements, fishing ports, guesthouses, and dive shops, and is attractive for its pristine scenery and local atmosphere.
Highlights
- Underwater scenery (diving and snorkeling): The area is rich in biodiversity, including coral reefs, tropical fish, and sea slugs. The water is highly transparent, and there are plenty of spots to enjoy for everyone from beginners to advanced divers.
- Beautiful coastline and beaches: The vivid colors of the shallow waters make for a photogenic landscape. Suitable for swimming and walking (please be aware of sea conditions).
- Sunset and starry sky: The small population makes for a beautiful night sky. The sea is especially beautiful at dusk.
- Local seafood: You can enjoy fresh seafood at guesthouses and restaurants near the fishing port (depending on the seasonal menu and the day's catch).
- Bridge and village scenery:The island scenery, connected to the mainland by a small bridge, and the laid-back atmosphere of the fishing village are also part of its charm.
