Three minutes across the Irabu Bridge from Miyako Island. What spreads out there is a sea of a blue you absolutely can't see on the Japanese mainland, and the quiet island time of an island with zero traffic lights.
Irabu Island is a small island of about 29 km² (11 sq mi), but it's packed with otherworldly scenic spots like Toguchi-no-Hama, 17END and Toriike Pond. Beyond the sights, the marine activities — snorkelling, SUP, the Blue Cave — are plentiful too. It's a place where, away from the bustle of Miyako Island, you can have a genuine remote-island experience.
This article covers it all: Irabu Island's sights, activities, model courses and how to get there. Whether it's your first visit or a return trip, it's structured so this single page completes the planning of your Irabu Island trip.
Irabu Island's Sights: 5 Best Beaches
Toguchi-no-Hama: Irabu Island's Most Beautiful Beach
The white-sand beach that represents Irabu Island. The extremely fine white sand and the sea's gradation from emerald to deep blue are stunning. It's a beach the islanders push so hard that a local will tell you, "cross the bridge, turn left, and it's straight ahead."
- Waves : calm, shallow — safe for families too
- Crowds : a little busy on summer afternoons. Before 9 am or in the evening is recommended
- Facilities : car park and showers available
Nakanoshima Beach: Into a Paradise of Fish by Snorkel
A hidden-gem beach on the Shimoji Island side. The fish are so dense it's described as "the moment I put on the snorkel mask and dipped my face in the sea, a gasp came out." The coral reef is rich, and the sight of colourful tropical fish dancing about is at a level even divers rave over.
- Features : high clarity and overwhelmingly dense fish
- Note : no showers or toilets. Change beforehand
- Recommended : in the morning, avoiding the low-tide window
Sawada-no-Hama: A "Top 100 Beach of Japan" with the Best Sunset
A beach chosen as one of Japan's 100 Best Beaches. The bright daytime sea is beautiful, but it shows its true worth in the evening. The setting sun dyeing the sky orange and reflecting off the sea's surface makes this one of Irabu Island's best sunset spots. Even those who go in the daytime and think "is that all?" will be moved without fail if they come back in the evening.
- Recommended time : evening, the 5–6 pm range (varies by season)
- Features : shallow and calm. After a typhoon, large rocks can wash ashore for a distinctive landscape
- Facilities : car park and toilets available
17END: Go Knowing the Gap Between the Instagram Shot and Reality
The shallows spreading off the northern end of Shimojishima Airport. It became famous for photos that look like walking on the emerald-green sea. However, the "walking on water" shots you see on social media can only be taken in the limited window at low tide. Many say "it was different from what I imagined." I strongly recommend checking the tide level before you visit.
- Best timing : at low tide (check the tide table in advance — essential)
- Note : few parking spaces; in summer they can fill by 8 am
- Access : past Shimojishima Airport and further north
Shinbiji: The White Stairway to Heaven
A scenic spot where pure white limestone steps lead down to a cobalt-blue sea — dubbed the "stairway to heaven." A hidden gem among hidden gems, with still few tourists. A fantastical view awaits that makes you doubt, "is this really real?"
- Features : little known, so almost no one is there
- Note : no signage, so access is a little tricky. Sandals aren't suitable
- Recommended : the morning window when the light hits
Irabu Island's Sights: 5 Best Nature and Viewpoint Spots
Makiyama Observatory: The Irabu Bridge and a 360° Panorama
The observatory with the best view on Irabu Island. The elevation is low, but nothing blocks the outlook, and you can survey the Irabu Bridge, Miyako Island and Shimoji Island. It's famous for strong wind, so always hold onto your hat. Even so, one look at this spectacle cancels out a bit of wind.
Toriike Pond: A Mystical Spot Divers Long For
Two ponds connected to the sea underground — a nationally designated natural monument that Irabu Island is proud of. The mystical water surface, described as "a blue that seems to draw you in," is well worth seeing just from land. Diving, you can experience the fantastical sight of blue light streaming in from inside the cave.
Funausagibanata: The Sheer Cliff at the Island's Northern Tip
A sheer cliff at Irabu Island's northern tip, with a name meaning "the cape where swallows take flight." The view of the sea looking down from atop the roughly 20 m (66 ft) cliff is stunning, and on a clear day you can survey all the way to Miyako Island. It's especially spectacular on windy days.
Yarabu Road: An Okinawa-Style Tree-Lined Drive
A scenic drive unique to Irabu Island, lined with an avenue of Yarabu trees (Alexandrian laurel). The sensation of driving through a tunnel of green is an experience particular to Okinawa's remote islands.
Miyako Shimojishima Airport: Japan's Most Stylish Airport
The airport itself is a sight. The clarity of the sea spread out right in front of the terminal is on another level, surprising travellers with "it's an airport, but you can see too much sea." A one-of-a-kind airport experience where even waiting for your flight isn't a chore.
5 Best Activities on Irabu Island
① Blue Cave Snorkelling: Irabu Island's No.1 Experience
Irabu Island's Blue Cave is the pinnacle even among the Miyako-area snorkelling spots. The sight of light streaming into the cave dyeing the water blue is something you'll never forget for the rest of your life. Joining a tour is reassuring, and it takes half a day to a full day. There are several plans, so choose to suit your purpose.
② SUP (Stand-Up Paddleboard)
SUP, paddling across Irabu Island's clear sea. In a calm-water inlet you can have a spectacular experience where the fish swimming beneath the board are in plain sight. Beginner-friendly guided tours are plentiful, so you can enjoy it even if you're not a strong swimmer.
③ A Loop of the Island by Sightseeing Taxi
For those not confident driving a rental car, or visiting Irabu Island for the first time, a sightseeing taxi is ideal. You can efficiently tour the main spots — Toguchi-no-Hama, 17END, Makiyama Observatory, Toriike Pond and more. The driver sharing local stories is one of the pleasures too.
④ A Tour of the Power Spots
Mystical power spots dotted around the island, such as Toriike Pond, Nudokubi Abu and Obiiwa Rock. We introduce a route that efficiently tours spots with such a distinctive atmosphere that the islanders describe them as "strange places."
⑤ A Village Walk (Sarahama)
A walk through the maze-like alleys of Sarahama village. In a historic settlement that flourished on bonito fishing, the lives of the locals still breathe today. The genuine everyday of Irabu Island, felt precisely because it hasn't been turned into a tourist site.
