Hirasawa, Shizuoka Prefecture.
This is a quiet sea in Japan that can be visited as a day trip from Tokyo.

From late spring to early summer, a special scenery appears in this sea.

A forest of seaweed extending to the water's surface.
A gently swaying green world.
Soft light filtering through.

It feels as if a forest is spreading underwater.

As you quietly swim between the seaweeds, small blue fish appear.
In the shadows of the rocks, small lives grow in the spring sea.

These seaweed areas are called "moba" in Japan.
They are important places where many fish and marine creatures live.

From spring to early summer, it is also the spawning season for the bigfin reef squid.
The changing scenery of the sea with each season is one of the charms of Japan's waters.

The sea of Hirasawa is a bit different from the tropical seas of Okinawa.
It lacks flamboyance.

However, it possesses a quiet beauty.

Light filtering through the seaweed.
A time when only the sound of waves can be heard.
The slowly flowing underwater scenery.

You can feel the gentle air typical of Japan's nature.

At Hokule'a Shonan, we offer guidance centered around the sea of Kanagawa and Izu, which can be enjoyed as a day trip from the Tokyo area.

With a small group, even beginners can feel at ease.
English support is also available.

Experience the time of Japan's sea that cannot be encountered just by visiting tourist spots.

It is recommended for those looking for "an experience in Japan that is more than just diving."

A short train ride from Tokyo leads you to a peaceful seaside experience. This time, I visited Zushi in Kanagawa Prefecture. It's a popular beach for day trips near Tokyo. The previous day was closed due to strong winds. Excited to see how the sea has changed, I headed to Zushi in the morning. Upon entry, a clear blue underwater world awaited. Countless damselfish. Sardines and mackerel swimming while reflecting the light. Schools of fish filled the water. The scenery was unlike anything you'd expect near Tokyo. But the charm of Zushi's sea doesn't stop there. Looking down a bit reveals a small world beginning. A goby hiding in the rocks. Colorful sea slugs. As I searched slowly, new discoveries came one after another. What impressed me most was the moment I saw a Sagami ryugu sea slug riding on a scorpion fish. Just a few seconds of a small event. Yet, such serendipitous scenes remain as memories of the sea. Time spent observing the schools of fish. Time spent looking for small creatures. In the same sea, you can enjoy completely different experiences. That's the allure of Zushi's sea. After diving, I had lunch at a local diner. The calm air after returning from the sea is one of the joys of traveling in Japan. A glimpse of another side of Japan that you won't encounter just by sightseeing in Tokyo. A tranquil world by the sea, right near the city. Hokule'a Shonan offers small-group diving tours near Tokyo. Beginners and solo participants are welcome. Why not experience a "day by the sea" during your trip to Japan? 【Related Keywords】 Tokyo Diving / Diving Near Tokyo / Kanagawa Diving / Zushi Diving / Dive Near Tokyo / Japan Diving / Hidden Japan / Japanese Ocean Experience / Tokyo Day Trip
