About this place
An island where emerald-green, crystal-clear seas unfold; the beauty is so striking that boats appear to hover as if suspended, and it is popular with divers. Kashiwajima is a tiny island connected by two bridges to Otsuki Town. Visibility often exceeds 25m, called 'floating boat' illusion due to crystalline water. Black Kuroshio Current brings tropical species, 1000+ fish species observed. Coral diversity high, designated marine park. Diving spots: Ace Point, 40m drop. The site embodies the intersection of natural geology, cultural lore, and contemporary tourism infrastructure.
Visitors can approach by public transport and private car, with clear signage in Japanese and English, parking and restroom facilities, and seasonal information boards.
Local cooperatives maintain trails and viewpoints, ensuring safety during wet or windy conditions. Early morning visits often reward with soft light, fewer crowds, and increased chances to observe wildlife, while late afternoon adds long shadows and warm coloration.
Combining this spot with nearby parks, shrines, hot springs, and culinary stops offers a full-day itinerary that supports the regional economy and deepens understanding of Kyushu and Shikoku heritage.
Photography, sketching, and quiet contemplation are encouraged, provided visitors respect vegetation, avoid litter, and observe no-entry zones protecting fragile rocks or sacred precincts.
Sustainability efforts, including erosion control, pine weevil care, coral preservation, and historic building maintenance, rely on entrance fees and local donations.
