[19:15] Sensuijima Island
Board on a desert beach in Sensuijima Island. Your guide will set up a break area on the beach. Put the bait for the sea fireflies in a bottle, scatter it in the sea, and wait for them to appear. Enjoy a Japanese picnic on the shore while waiting, or go for a stroll on the shore. You can also decide to bathe in the sea!
When the jars are full of luminescent fireflies, your guide will diverse them on the shore for you to enjoy the blue glow from up close.

The glowing sea fireflies will start to appear and make your world turn a shimmering blue. This is the moment to get some wonderful photos. You might be lucky enough to witness sea plankton highlighting the movement of your paddle on the water with their glow.

[21:30] Return to Tomonoura Port
Say goodbye to the fireflies and kayak back to Tomonoura.


Tomonoura port is well known for being one of the inspirations of the Studio Ghibli's movie Ponyo on the cliff by the sea. However, this evening tour will guide you through the wonders of nature on the ocean's summer nights to witness the enchantment of sea fireflies on the shore of the Seto sea. They are minuscule bioluminescent crustaceans, quite uncommon in Japan, that glow a blue light in shallow waters during the summer months (June to October).

Mister Murakami will guide you safely through the islands of the area, while enjoying the sunset from your kayak or canoe. On your way, enjoy starkly different scenery from the daytime, such as an illuminated shrine gate. Feel the power of nature as your embarkation slide on the peacefully dark waters. When you arrive at Sensuijima Island, open your heart to the magical world of shining blue. A small picnic prepared by a local restaurant will be taken on the beach, while waiting for the bait to attract enough sea fireflies. It's sure to be a photo-worthy experience if your camera tolerates low light.

No doubt that this experience will glow brightly in your Japan memories!

※We highgly recommend you to book a night in Tomonoura port to enjoy this experience worry free.
