Snorkeling on Uguru Island

A sea where 90% of guests
encounter sea turtles

Uguru Island, Kochi Prefecture —
a remote island of just 20 residents.
You can see coral reefs from the harbor wall,
and sea turtles swim right beside you in the water.

Swim, Fish, and Feast —
A Day on Uguru Island

Three unforgettable experiences,
only on Uguru Island.

01

Boat Snorkeling

Head straight to the best spots by boat. With a 90%+ sea turtle encounter rate, you'll swim alongside coral reefs, tropical fish, and large pelagic species.
Beginners are welcome — we provide a full briefing on the beach beforehand.

Main Activity
02

Pier Fishing

The water is so clear you can see the fish before you catch them — an experience unique to this island.
Even beginners land fish thanks to the incredible visibility.
Your catch goes straight to lunch. All gear is included.

Optional
03

Freshly Caught Seafood Lunch

This is a special lunch experience where you can prepare and cook the fish you catch yourself. Deep-fried fresh fish is exceptionally delicious.
Even if you don't catch any fish, we offer an original curry made with squid from Sukumo, or a daily sashimi lunch. Enjoy the bounty of the sea to the fullest!

Lunch Included

Sights you simply cannot
see on a day trip.

A sky full of stars with
zero light pollution at night.
Solo fishing at dawn on a deserted sea.
A dinner table set with fish you caught yourself,
shared with our staff.
This is what the overnight plan is all about.
