Overview

Experience the magical bioluminescent marine life of Tamano, on the Seto Inland Sea near Naoshima.

Led by Trevor, an experienced photographer with more than 14 years of observing and photographing local bioluminescence, you’ll discover the fascinating world of sea fireflies, glowing phytoplankton, and the unique marine environment of the Seto Inland Sea. The experience combines discovery, education, and responsible interaction with local marine life. Perfect for families, couples, photographers, nature lovers, and travelers visiting Naoshima and the Setouchi islands, this intimate nighttime experience offers a rare opportunity to encounter one of Japan’s most enchanting natural phenomena.
