What Is Imgya Marine Garden’s ‘Natural Pool’?

An Inlet Formed by Wave Erosion

Imgya Marine Garden is a natural inlet formed by wave erosion. The bay’s structure is separated from the open sea, with calm waves, making it a swimming and snorkeling spot that’s reassuring even with kids.

The Meaning of ‘Imgya’

‘Imgya’ means ‘enclosure of the sea’ in the Miyako dialect. Literally a natural pool where the sea is surrounded by land, it’s a scenic spot true to its name. The water is highly transparent, and you can casually enjoy snorkeling within the inlet.

The View from the Observation Deck

From the observation deck linked by a promenade, you can look down over the entire bay. The contrast of the emerald-green sea and white sandy beach is as beautiful as a painting.

Snorkeling at Imgya Marine Garden

A Beginner-Friendly Environment

Snorkel Gear Rental

There’s also a snorkel gear rental shop near the beach. A set of mask, snorkel, and fins runs about 1,500–2,500 yen per day. You can enjoy snorkeling casually even if you come empty-handed.

Imgya Marine Garden’s Facilities

Showers and Changing Rooms

In summer (April–October), showers and changing rooms operate. They’re convenient for changing and rinsing off the salt after playing at the beach. Use may be free or coin-operated.

Restrooms and Parking

Restrooms and free parking are provided. The parking is spacious enough for tour buses. It gets crowded in season, so arriving early is recommended.

Shop and Vending Machines

Around the beach there are vending machines and an in-season shop. It’s best to prepare water and snacks in advance.

How to Enjoy Imgya Marine Garden Safely

The Best Timing for Swimming

At high tide, there’s more depth, making snorkeling easier. Conversely, at low tide it becomes shallow, raising the risk of touching the coral. Check a tide table in advance.

Precautions When Swimming

• Life jacket wearing recommended (especially with kids)
• Marine shoes to protect your feet from coral
• Sun protection essential (sunscreen, rash guard)
• Don’t touch the coral (etiquette to protect the coral)
• Watch for rip currents (especially after a typhoon)

What to Do in Bad Weather

Swimming is prohibited in strong wind and when a typhoon is approaching. It’s safer to avoid days with high waves too. On rainy days, just enjoying the view from the observation deck is worthwhile on its own.
