Day trip diving at a sunken ship from Tokyo.
Another Japan sleeping in the sea of Atami.

About 45 minutes by Shinkansen from Tokyo.
Atami, known as a hot spring resort, has a special place under the sea.
A large sunken ship lies at a depth of about 30 meters.

On this day, we headed to the sea of Atami with guests from overseas and divers who were diving at a sunken ship for the first time.
It takes just about three minutes by boat from the port to the diving point.
Right near the city, there is a sea where you can enjoy authentic sunken ship diving.

Entering the water, we slowly descend along the rope.
Gradually, the shape of a large ship emerges in the blue sea.
Surrounding the ship are numerous fish.
A large school of damselfish swims around the sunken ship.

The ship's hull is visible beyond the school of fish.
The view is completely different from what you see on land in Atami.
It has been about 40 years since this ship sank into the sea.
Having spent a long time underwater, it has now become a habitat for various living creatures.

As the hull gradually changes its appearance, there are different discoveries every time you visit.
If you shine a light and peek into the hull, you might find remnants of the ladders that were used back then.
You may also encounter a large grouper.

The first dive is on the bow side.
The second dive is on the stern side.

Even with the same sunken ship, changing the diving spot alters the scenery.
You can swim while admiring the massive ship, navigate through schools of fish, and observe what remains of the ship.

A ship from about 40 years ago and the marine life of today.
The charm of diving at the sunken ship in Atami is being able to see both at once.

After finishing the dive and coming out of the sea, you find yourself in Atami, one of Japan's leading hot spring resorts.
While being a day trip distance from Tokyo, you can enjoy a day that is a little different from the usual Japanese sightseeing.

About one hour from Tokyo. A day spent enjoying summer in Japan by the sea. As the rainy season ends, summer truly begins in Japan. In this hot season, why not take a little break from the city and head to the beach? Just a 30-minute drive from Hokulea Shonan, the destination is Enoura, a small seaside town in Kanagawa Prefecture. Although it is a place you can visit on a day trip from Tokyo, time flows differently there compared to the city. The blue sky. The calm sea. Just listening to the sound of the waves naturally relaxes your mind. And then, into the water. The moment you enter the sea, the cool water envelops your entire body. This comfort makes you forget the summer heat. "I want to dive a little longer." It felt like I could hear such voices throughout the day. In this season, there are summer-only scenes beneath the sea. Clownfish have begun to spawn. The sight of parent fish carefully protecting their eggs is a special scene you can only encounter at this time. Diving is not just about enjoying the underwater scenery. Visiting a seaside town, feeling the seasons, and experiencing Japan's natural beauty. Such moments are also an important part of this experience. For those with a license, of course, we also offer introductory diving for beginners. How about adding a day at the sea to your Tokyo trip?
