Discover Takegashima Underwater Park
Often described as a “gem of the southern seas,” Takegashima Underwater Park offers an enchanting combination of brilliant blue water, scattered islands, coral reefs, and abundant marine life. Located off the northwestern part of Takegashima Island, the park is a wonderful destination for visitors who want to experience the natural beauty of Japan’s Pacific coast.
Visitors can explore the marine environment through activities such as diving and sea kayaking, or enjoy the underwater scenery from a sightseeing boat. The clear water and diverse marine ecosystem make this an especially appealing destination for nature lovers and anyone curious about the world beneath the waves.
Take a Cruise on the Blue Marine
The sightseeing boat Blue Marine departs from Takegashima Port and takes visitors on a cruise around the underwater park. Tickets can be purchased at Marine Jam Ocean Natural History Museum, the white building located just across Takegashima Bridge.
The museum introduces the park’s marine environment and natural history, allowing visitors to learn about the underwater ecosystem before setting off on their cruise. A visit to the museum is a useful way to deepen your appreciation of the coral reefs and marine life you may encounter during the trip.
The Natural Wonders of Takegashima
Coral Reefs and Marine Life
More than 20 species of coral inhabit Takegashima Underwater Park, creating important habitats for a wide variety of marine creatures. In the exceptionally clear water, colorful fish can be seen swimming among the coral formations. The area is a popular destination for diving and sea kayaking, offering opportunities to experience its underwater beauty at close range.
However, some coral has been lost in recent years due to environmental pressures, including pollution. Protecting the marine ecosystem is therefore an important part of preserving this remarkable natural attraction for future generations.
Island Attractions and Unusual Rock Formations
Takegashima Island itself has plenty to explore. Among its attractions are Takegashima Shrine and Marine Jam Ocean Natural History Museum. The island also contains a bamboo grove measuring approximately 50 meters on each side, which is said to have inspired the island’s name.
Visitors can also discover unusual rock formations with names such as Summit Stone, Monk Rock, Turtle Rock, and Wobbling Stone. These distinctive natural features add to the island’s charm and offer a glimpse of the striking geological scenery shaped by nature.
Explore the Underwater World from the Blue Marine
One of the highlights of Takegashima Underwater Park is the approximately 40-minute cruise aboard the Blue Marine. The boat travels through an area known for its rich coral communities, allowing visitors to enjoy the marine scenery without having to dive into the water.
A glass-bottom observation room beneath the boat provides views of the underwater world from a comfortable seated position. Through the windows, passengers can observe coral formations and fish moving through the clear water. The scenery changes with the seasons and ocean currents, making each cruise a slightly different experience.
Branching and Honeycomb Corals
From the boat’s observation room, visitors may see coral communities that include branching corals such as *Acropora* and massive coral formations known as *Porites*. Colorful fish darting between the corals create a vivid tropical scene, bringing the beauty of a southern island sea to Japan’s Pacific coast.
Marine conservation efforts help protect these fragile underwater habitats. Visitors can contribute by respecting the natural environment and enjoying the park responsibly.
Diving and Sea Kayaking
For travelers who want a closer encounter with the sea, Takegashima Underwater Park also offers opportunities for diving and sea kayaking.
Diving: Divers can observe coral formations and marine life at close range. The underwater environment offers an engaging experience for both beginners and experienced divers, with suitable activities depending on conditions and individual skill levels.
Sea kayaking: Paddling across the clear water provides a peaceful way to explore the coastline and admire the small islands scattered around the park. From the water, visitors can appreciate the relationship between the island scenery, rocky shores, and surrounding sea while enjoying a close connection with nature.

Tropical-Like Coastal Scenery

Small islands rise from the water, while coral reefs flourish beneath the surface, creating a landscape of exceptional beauty.
The sea changes its appearance throughout the year, offering new colors and views with the changing seasons and ocean conditions. Whether admired from the sightseeing boat, explored by kayak, or experienced underwater, Takegashima’s scenery provides a memorable glimpse of Japan’s subtropical marine environment.
