Okayama: Bioluminescent Marine Life Night Experience

Experience the magical bioluminescent marine life of Tamano, on the Seto Inland Sea near Naoshima. More than a wildlife-viewing tour, this is a hands-on experience where you’ll use specially designed equipment to collect sea fireflies, observe their brilliant blue bioluminescence up close, and safely release them back into the sea. 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. Selected as a finalist for the Japan Tourism Awards 2027.

As night falls, leave the crowds behind and join a small-group adventure to witness one of Japan's rarest natural experiences. Along a quiet shoreline in the Seto Inland Sea, you'll discover tiny bioluminescent sea fireflies and glowing blue plankton that illuminate the water after dark. Your guide will introduce the fascinating science and history behind these remarkable creatures before showing you how to safely collect sea fireflies using simple, environmentally responsible methods. You'll have the rare opportunity to observe their brilliant electric-blue glow up close before they are carefully returned to their natural habitat. Throughout the evening you'll also search for glowing plankton, creating breathtaking flashes of blue light in the sea. Along the way you'll learn about the local marine ecosystem, conservation efforts, and the unique conditions that make this phenomenon possible. This intimate, hands-on experience combines nature, science, and wonder, offering an unforgettable night that few travelers to Japan ever have the chance to experience.
