A First Look at MIYAKO GALAXY-DOME and a Stay at Seawood Hotel

Miyako Island is best known for its vivid blue waters, often called Miyako Blue, but there is another side to the island after sunset: its star-filled night sky.

I joined an advance preview before the facility opened, experiencing its immersive LED dome firsthand and seeing how live telescope images are combined with planetarium visuals.

I also stayed at Seawood Hotel, so this report covers both the new astronomy experience and what it’s like to stay at the resort.

Just across Kurima Bridge from Miyako Island, Kurima Island offers excellent conditions for stargazing, especially after dark. At 24 degrees north, roughly the same latitude as the Northwestern Hawaiian Islands, the island is far enough south that, under the right conditions, you may even spot the Southern Cross, which is rarely visible from Honshu, as well as Canopus, the second-brightest star in the night sky.

Kurima Island was also rated in the highest category of a 2024 night-sky survey conducted by Japan’s Ministry of the Environment, recognizing its dark skies and the visibility of features such as the Milky Way and star clusters.

With skies this dark, Kurima Island is an ideal location for MIYAKO GALAXY-DOME.

What Makes It Japan’s First

This is Japan’s first planetarium experience to combine an observatory equipped with telescopes and an LED planetarium.*

*As of March 1, 2026

The key feature is the direct link between the two domes. Live images captured by several telescopes in the OBSERVATORY DOME are sent directly to the adjacent PLANETARIUM DOME.

I was also able to see a live view of the Moon, with the same image projected inside the planetarium.

For children, seeing the Moon and stars up close could even inspire a summer science project.

Vivid, high-definition images of celestial objects fill the 7.5-meter-wide LED dome. With images and even sound seeming to pour down from above, I felt as though I were gently drifting through space.

Day and Night at MIYAKO GALAXY-DOME: Two Guided Tours

MIYAKO GALAXY-DOME offers two guided tours at different times of day, both with live commentary.

[Afternoon to Early Evening] Preview Tonight’s Sky on the PLANETARIUM TOUR

Held at 4 p.m. and 5:30 p.m., while it is still light outside, the PLANETARIUM TOUR recreates the night sky expected over Miyako Island that evening.　A presenter introduces the planets visible that night, shows each guest where their birthday constellation appears in the sky, and offers tips for spotting them later that evening.

The tour also includes astronomy films that showcase the fine detail of the LED dome.

[Night] See Live Telescope Images on the STARGAZING TOUR

At 8:30 p.m., the STARGAZING TOUR begins as the observatory dome opens to the night sky.

High-performance telescopes capture live views of nebulae, star clusters, planets, and other celestial objects, which appear one after another across the neighboring LED dome. Unlike looking through a telescope eyepiece yourself, electronic observation allows everyone to share the same ultra-high-definition view of the universe on a large screen.

The tour ends outside under the real night sky. When I spotted a constellation I had just seen inside the dome, I got goosebumps.

Live Commentary That Feels More Like a Show

The live commentary is a key part of the experience.

My session was led by a guide known as the “Star Gentleman,” who had spent many years working as a nature guide on Hawaii Island. His lively mix of astronomy, humor, and stories about the stars drew me in almost immediately. It felt more like a live show than a lecture, making it easy for both children and adults to get caught up in the experience. The warm, informal atmosphere was quite different from the planetarium shows I was used to in Tokyo.

Reservations & Details

A Blissful Resort Escape: Staying at the Miyakojima Kurima Resort Seawood Hotel

Home to MIYAKO GALAXY-DOME, Miyakojima Kurima Resort Seawood Hotel opened in February 2020. Set across expansive grounds, the resort feels almost like a town of its own.

Exploring the Resort’s Five “Houses”

The resort’s expansive 130,000-square-meter grounds are divided into five “houses.” These include Ryugu House, home to the front desk and Japanese restaurant, and Beach House, where the main pool is located.
Accommodation comes in two main types:

Shuri House (Hotel Building): A 62-room hotel building with balconies offering views of the surrounding scenery

Villa House (Standalone Villas): 107 private villas, each with its own pool or whirlpool tub.

The villas feature high ceilings and open layouts, along with private outdoor spaces and pools or whirlpool tubs.

With the resort’s facilities spread across a large area, electric carts are available to help guests get around. I enjoyed riding between buildings, with the breeze blowing as I made my way around the grounds.

Since I was traveling alone, I stayed in Shuri House, the hotel building. My room was spacious enough for two people to stay comfortably.

From Kaiseki to a Resort Breakfast: Dining at Seawood Hotel

Dining at Seawood Hotel was one of the highlights of my trip. Guests can enjoy the cuisine of Kissho, a long-established Japanese restaurant in Ginza, Tokyo.
The resort has two restaurants: Japanese Cuisine Kissho Kurima Island, which serves traditional kaiseki cuisine, and the bright, open Beach House Restaurant. Dinner features fresh seafood from around Miyako Island and Miyako beef.
I had breakfast at Beach House Restaurant, where the buffet included both Japanese and Western dishes. Omelets were cooked to order, and I could even boil my own Miyako soba, adding a fun, hands-on element to the meal.

The Japanese selection included dishes such as jūshī, an Okinawan-style mixed rice dish, as well as locally caught fish.

The Western selection included freshly made omelets, warm bread, and 100% grapefruit juice.

The buffet also featured plenty of Okinawan and Miyako Island specialties, making it a great way to sample local flavors before heading out for the day.

Bring Your Camera: Five Photogenic Spots Around Seawood Hotel

The resort grounds are dotted with photogenic spots, and I was reaching for my camera almost immediately. An electric cart made it easy to explore them.

1. The Grand Arch at Ryugu House

The Grand Arch stands at the resort entrance, framing the view beyond.

At magic hour, the sky behind the arch shifted through layers of color, and I had to stop to take it all in.

2. The Reflecting Pool

Beyond the arch, a reflecting pool stretches beneath the sky.

When I stepped into the center, the reflected sky seemed to stretch beneath my feet. In the photo, it looked as though I were standing right on the water.

3. Shuri House Rooftop Observation Deck

From the rooftop observation deck, I could see Kurima Island’s greenery, the vivid Miyako Blue sea, and the distant horizon all at once.

4. "Ocean Art" on the Central Staircase

A seascape stretches across the steps, and from the right angle, the person in the photo seems to become part of the painted ocean.

5. Nagamahama Beach

Nagamahama Beach is only a short walk from the resort. Its white sand and clear water make it a beautiful spot for daytime photos, while the open shoreline offers an unobstructed view of the sunset in the evening.

A Stay That Brings Island Wildlife Up Close

A bird’s sweet chirping drew me to the window, where I found a small bird perched on the balcony.

While walking along the beach, I spotted a pale crab almost the same color as the white sand, which suddenly bumped into my shoe.

On an evening walk, I spotted large hermit crabs and other crabs along the road—creatures rarely seen in the city.

The staff also shared interesting facts about the wildlife around the resort during the cart rides, making even the short journeys more enjoyable.

Electric carts are available 24 hours a day and can be requested using the phone in your room.

A New Way to Experience Miyako Island After Dark

Looking back on my stay, I realized how naturally one scene had led into the next. The Miyako Blue sea shimmered in the sun, the sunset glowed through the Grand Arch at Ryugu House, and after dark, MIYAKO GALAXY-DOME drew my gaze to the stars.
"After experiencing it for myself, I could see the appeal of adding MIYAKO GALAXY-DOME to a nighttime itinerary on Miyako Island. Since opening on June 1, 2026, it has given visitors another reason to stay out after sunset.

At Seawood Hotel, the sea, sunset, and stars all became part of the same stay, with MIYAKO GALAXY-DOME extending the experience into the evening."

MIYAKO GALAXY-DOME Q&A: What to Know Before You Go

Q. Can I join the tour even if I'm not staying at the hotel?

A. Yes. Day visitors can join the PLANETARIUM TOUR or STARGAZING TOUR for ¥5,500 per adult, while Seawood Hotel guests and Miyako Island residents pay ¥4,400. Advance booking through the official website is recommended.

Q. Can babies and young children join the tours?

A. Yes. There is no minimum age, and preschool-age children can join for free. The dome becomes dark during the show, but staff are available to help. The lively commentary can also help younger guests stay engaged throughout the tour.

Q. Is parking available, and how do I get there by car?

A. Yes. Free parking is available at Seawood Hotel. The hotel is about a 20-minute drive from Miyako Airport and 40 minutes from Miyako Shimojishima Airport. The drive across Kurima Bridge offers beautiful views along the way, and the resort is easy to reach by rental car as well.

Q. What happens if it rains or is cloudy? Will the tour be canceled?

A. No. Because the facility is completely indoors, you can still enjoy the experience even when the weather is poor. Even when the real night sky is not visible, the 7.5-meter LED dome recreates Miyako Island’s star-filled sky, accompanied by visual programs and lively live commentary. It can be a great option for a rainy day on Miyako Island.

Q. What should I wear or bring for the stargazing tour? Can I take photos with my phone?

A. A light long-sleeved layer and insect repellent are useful for the stargazing tour, even in summer.
Smartphone photos: Newer smartphones can capture the stars quite well. Using Night mode and keeping your phone completely still for several seconds can help. A compact tripod is also recommended to prevent camera shake.
