Por qué es tan popular
An outlying island at the far south-western tip of Kōchi Prefecture (linked to the mainland by bridge), more than 3 hours' drive from Kōchi city — its remoteness has spared it from mass tourism. The water's transparency averages 20 m and reaches up to 40 m, with about 1,000 species of fish; divers call it 'a sea you must dive once in your life', yet ordinary visitors know little of it.
Culture
Cultura y costumbres
Contexto cultural
Kashiwajima is part of Ashizuri-Uwakai National Park; the Kuroshio current and the Bungo Channel meet here, bringing rich fishing grounds, and the island is a traditional set-net fishing village; the remarkable sight of 'boats seemingly floating in the air' comes from pure seawater with no pollution from household waste.
Costumbres locales
- Book snorkelling and diving through licensed local shops — don't go in alone
- don't touch or step on coral
- take all rubbish off the beach
- don't get in the way of fishermen working in the harbour.
Religión y creencias
No particular religion. The fishing village has a faith in 'safety at sea', and locals pray silently before going out.
