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.

Experience summer ahead of time at the Izu coast. Just a short distance from Tokyo, a summer sea awaits. This time, I visited Kawana and Shobuzawa in Higashi-Izu. With the blue sea and summer sunshine, it's a weekend to feel the essence of a Japanese summer a little early. The first dive was at a limited-time boat point in Kawana. As I entered the water, I was greeted by a school of fish filling my view. There were so many fish that I couldn't see the diver swimming in front of me. It's a rich underwater landscape unique to Japan. After enjoying the dive, we headed to Shobuzawa. In the evening, we enjoyed a BBQ by the seaside. Surrounded by the sound of waves, we shared stories about the day's events. It's a relaxed summer night that can only be experienced while traveling. The next day, we headed to a popular shipwreck dive site. However, due to the typhoon swells, the water visibility was only 30 cm. In nature's sea, you can't always meet the same scenery. Still, spending time accepting the day’s sea is one of the charms of diving. This time, it became an unforgettable two days filled with encounters with beautiful schools of fish, BBQ with friends, and the birth of advanced divers. Japan's summer is just getting started. Enjoying the sea, local cuisine, and spending holidays in nature. Let's experience these unique Japanese adventures together. — A special day by the sea in Japan. 🌈 Hokulea Shonan is a small diving shop located in Hiratsuka City, Kanagawa Prefecture.
