Where is Kozushima, Tokyo's remote island?

Kozushima is one of the Izu Islands, a remote island off the coast of Tokyo. It takes just 45 minutes by plane from Tokyo to get there, and it's hard to believe it's in the same Tokyo area. The island is rich in nature and has a unique historical and cultural background, and is packed with attractive spots. We will introduce some activities you can enjoy in the beautiful sea.

Please see the article below for how to get to Kozushima.

Dive into the crystal clear waters at Akasaki Promenade

The most famous marine activity spot on Kozushima is Akasaki Promenade!
A wooden walkway built into the rocks leads to an observation deck from which magnificent views can be enjoyed.
What's more, jumping off the diving board is thrilling and exhilarating!
When you jump into the ocean, you'll find plenty of fish waiting at your feet.

After diving in, go snorkeling and enjoy the crystal clear emerald green waters.

Enter the blue world! Try scuba diving

Kozushima has been selected as the beach with the most transparent water in Japan and the cleanest water quality.
The best way to enjoy this transparent and beautiful blue world is through scuba diving!

Anyone with a scuba license can enjoy the diving, even if they don't have one, you can do a trial course.
There are four diving shops on Kozushima, where experienced instructors will be happy to show you around.

Even beginners can aim for big fish! Boat fishing experience

If you'd like to try another challenge, how about fishing?
We recommend boat fishing, an experience that can only be had on an island! You can rent all the necessary equipment, such as fishing rods and bait, so it's okay to go empty-handed. The experienced captain will teach you how to fish, so even if it's your first time fishing, you might be able to catch a big fish!

They will also help you arrange to have the fish you catch sent to your home. There are no places on Kozushima that offer fish filleting services. Most accommodations offer place to fillet the fish by yourself, so if you want to take it back, be sure to check with the accommodation staff before doing so.

The fish that can be caught change depending on the season, so it is an activity that can be enjoyed at various times of the year, not just in summer.

It's like being in space! A bioluminescent cruise

*This is an image generated by AI.

A recommended tour that is only held during the summer is the bioluminescent plankton tour.
Noctiluca, also known as sea sparkls, are marine plankton that emit a faint blue light when struck by waves or other forces.

The bioluminescent plankton tour involves boarding a fishing boat and heading out to sea at night.
When the lights on the boat go out, the sea turns dark and the sparkling light show begins, following the boat's wake...!
The captain will teach you how to enjoy the night sea in various ways.
And when you look up, you'll see a sky full of stars! The sky and the sea both shine brightly, making you feel as if you're in space.

Because it emits a very faint light and the boat sways back and forth, it is nearly impossible to capture on camera or video.
Capture the special experience with your mind camera and make it a lasting memory.
