A Thorough Look at What an Unmanned Hotel Can Do
I still vividly remember the first time I stayed at an unmanned hotel. I arrived at Blue Cove Terrace on Irabu Island past 9 at night, parked in a pitch-dark car park, and panicked for a moment — "huh, where's the front desk…?"
I found the tablet placed at the entrance, entered my booking number, took out the key, and didn't talk to anyone until I entered the room. At first I was a bit anxious, but the moment I entered the room I thought "ah, this is incredibly nice."
A spacious room with a washing machine and dryer, a mini kitchen, even a fridge, with the feeling of being like my own apartment. And the sea is right in front, 2 minutes by car to Toguchi-no-Hama. "At around ¥10,000 a night, isn't this too good value…?" I was honestly surprised.
For people looking for a long-stay or diving base on Irabu Island, I'll write realistically about what Blue Cove Terrace is actually like. How is an unmanned hotel really? Isn't it inconvenient? Does it suit a long stay? I want to answer such questions based on real experience.
What Kind of Hotel Is Blue Cove Terrace, Really?
Blue Cove Terrace, which opened in December 2020, appeared as the first casual resort hotel with a mini kitchen, washing machine and dryer in the Irabu Island and Shimojishima area. The location is about 6 minutes by car from Shimojishima Airport, about 30 minutes from Miyako Airport. It's in the central part of Irabu Island, a location convenient for both sightseeing and marine activities.
There are 24 rooms in all, all about 30 m² twin rooms. There's a sofa bed too, so up to 3 people can stay. With a motel-type build, you can park right in front of each room, which is a feature. Getting luggage in and out is easy, and it's incredibly convenient for people with big luggage like diving gear.
It uses an unmanned self-check-in system, so not having to mind your arrival time is the best. Arrive late at night or set off early in the morning, you don't have to mind anyone. This is, I think, a surprisingly important point.
Out front there's a restaurant called "Shokusaitei Mutsumi," where you can eat breakfast. It operates as a set-meal place for lunch and an izakaya at night, so you won't be stuck for meals. However, note that Monday is the closed day.
Looking at the official site, there are updates from late 2024 into 2025, so it's still operating normally. I'd heard a rumour it was closed for a while, but at least as of December 2025 you can stay without problem.

The Room Facilities Are Seriously Substantial
The first thing I thought entering the room was "spacious." 30 m² might not feel that spacious just looking at the number, but actually entering, it's more than enough for solo or two-person travel. There are twin beds with plenty of room, plus a sofa and table.
Having two washbasins is quietly nice. You don't fight over them in the morning prep, and even using it alone you can brush your teeth and wash your face at the same time (haha). The toilet and bath being separate is also calming for a Japanese person. Not being a unit bath is truly important on a long stay.
The mini kitchen is fully equipped with an IH stove, microwave and fridge. Full-fledged cooking is a bit hard, but simple cooking is totally possible. Being able to buy ingredients at the nearby Maruki Supermarket, make breakfast in the room or eat cup noodles late at night is truly welcome.
And above all, having a washing machine and dryer in the room is the strongest. Diving and snorkelling on Irabu Island produces wet things every day. Being able to wash and dry them in the room is incredibly convenient. No need to find a coin laundry and travel by car, no need to wait until the wash finishes. You can do laundry in the room whenever you like.
However, there's basically no cleaning during the stay. Towel changes and amenity refills are a self-service system where you go get them yourself at the ground-floor library space. At first I thought "huh, no cleaning?" but conversely no one comes into the room, so it was relaxing. I think it suits people who value privacy.
The provided amenities are toothbrush, hairbrush, razor, body towel, shampoo, conditioner, body soap, hand soap, deodoriser, hairdryer, electric kettle. The bare minimum is there. It's more certain to buy what's missing on Miyako Island, though.
With an electric kettle, you can drink coffee or tea in the room. Come back from the sea, shower, brew coffee, and relax on the sofa. This time was supremely happy.
The building has a vending machine (water, alcohol, snacks) and an ice machine too. You're fine if your throat gets dry in the middle of the night, and you can buy beer to drink in the room. The hotel water is softened, so it's usable as drinking water too. This is a quietly important point too.
The Reality of Unmanned Self-Check-In
Hearing "unmanned hotel," many people probably feel anxious. I did at first too. But actually experiencing it, the merits are bigger.
Check-in is completed on the tablet placed at the entrance. Just enter your booking number and proceed following the screen instructions. For someone used to it, it takes less than 5 minutes. But looking at reviews, there were voices like "the operation was complex and hard to understand" and "there was no explanation at all and I was stuck." Indeed, at first you might be a bit bewildered.
In fact, when I arrived it was late at night and no one was there, so there was a moment I got anxious in front of the tablet — "is this right…?" But read the screen carefully and operate calmly and it's fine. If you get stuck, calling the emergency contact gets you support.
Check-out is easy too. Just put the key in the return box and do the procedure on the tablet. For people who want to set off early or relax without minding the time, I think it's the best system.
However, it doesn't suit people who expect staff service. People who want "tell me recommended sightseeing spots" or "respond immediately if there's trouble" are better off choosing an ordinary hotel.
The response when something goes wrong is also basically by phone or email. For people of the type who want to talk to a person in real time to solve things, it might be a bit stressful.
But conversely, you can act freely without minding check-in time, and you're never kept waiting at a front desk. For people who dislike talking to others, it's actually comfortable. It depends on your values.
Breakfast at the Restaurant Next Door
Blue Cove Terrace's breakfast is eaten at "Shokusaitei Mutsumi" in front of the hotel. It was apparently formerly called "Janjan Irabu," but now operates as "Shokusaitei Mutsumi."
Breakfast is buffet-style, 7:00–10:30. The content changes daily — miso soup or soup, bread, beef curry, salad, fruit and so on. Drinks are free-flowing too. Looking at reviews, there are many saying "the bread is delicious and the beef curry is delicious too."
It operates as a set-meal place for lunch and an izakaya at night, so the meal options widen. However, Monday is the closed day, so if you stay on a Monday you need to eat elsewhere.
Irabu Island is surprisingly a gourmet island, with quite a few delicious places. "BOTTA" near Sawada-no-Hama is a popular shop where you can eat authentic Neapolitan pizza while seeing the sea. I went too, and the view and taste were both the best.
"Irabu Soba Kame" is a shop where you can eat soba unique to Irabu Island. The broth using namari-bushi (half-dried bonito) is rich in flavour and goes well with the chewy noodles. It often has a queue, so going at an early time is recommended.
"New Hamaya" is an eatery where you can enjoy creative dishes making the most of local ingredients. The "Sarahama bonito tataki" is a popular menu item, with many repeat customers.
"Soraniwa Cafe," attached to the Soraniwa hotel, is also a lovely place where you can relax while seeing the sea. Being near Toguchi-no-Hama, it's just right to drop by on the way back from the beach.
If you're buying ingredients to cook in the room, "Maruki Supermarket" or "Super Minamiha" is convenient. Maruki Supermarket is on the ground floor of Hotel South Island and sells handmade bento too. Super Minamiha is in the inland part of Sawada-no-Hama, with substantial handmade deli dishes too.
Irabu Island has only one convenience store. FamilyMart Miyako Irabu, at the corner where Prefectural Routes 90 and 204 cross. It's open until late at night, so it helps when you suddenly need something.
Why It Suits a Long Stay
Let me list, from real experience, the reasons Blue Cove Terrace suits a long stay.
First, the pricing. According to the official site, for a long stay a substantial discount applies in stages. If you stay a week or 10 days or more, it becomes quite a deal. The official site even says it suits workation, migration trials and sports training camps, so it's made with long stays in mind.
With a washing machine and dryer in the room, you don't need to bring a lot of changes of clothes. This is truly important on a long stay. Your luggage decreases, and you can always wear clean clothes. Playing in the sea requires laundry every day, so a washing machine in the room is a godsend facility, I think.
With a mini kitchen, you can self-cater rather than eating out all the time. Eating out every day costs money and tires the stomach. Just being able to make a simple breakfast or heat up a late-night meal raises the comfort level considerably.
The room is spacious, so even a long stay doesn't feel cramped. You can spread out a laptop and work, and there's room to spare even spreading out luggage. I saw in reviews that many people come for workation, and I think it's an understandable environment.
The car park is free, and you can park right in front of each room. Getting luggage in and out is easy, and it's perfect for Irabu Island sightseeing where travel by car is the main thing. For people renting a car and staying long, it's the best environment.
With no cleaning, you can spend it at your own pace. You don't have to vacate the room at a fixed time daily, and privacy is protected. For a type like me who dislikes people coming and going, it was actually a welcome system.
Being close to Shimojishima Airport, the access is convenient too. Direct flights from Tokyo and Kansai to Shimojishima Airport have increased, and the low travel burden is a long-stay-friendly point too.
The Location Is Insanely Good
Blue Cove Terrace's location is honestly incredibly good. Of course Irabu Island's sightseeing spots, but it's close to Shimojishima's beaches too.
About 2 minutes by car to Toguchi-no-Hama. Said to be Irabu Island's No.1 beach, about 800 m of white sand spreads in a bow shape. The sand is incredibly fine, and walking barefoot it's fluffy and pleasant. Being a shallow flat, even families with children can play safely.
However, Toguchi-no-Hama is prone to rip currents, so care is needed for swimming. Playing in the calm-wave area on the breakwater side is safe. There are no lifeguards either, so it's an enjoy-at-your-own-risk feel. People who want to swim seriously might be better off at a beach with lifeguards, like Yonaha Maehama.
About 10 minutes by car to 17END. A phantom beach that appears only at low tide, said to have Miyako Island's top transparency. The sight of pure-white sand and a gradient-like blue sea spreading out is exactly a superb view.
It's at the end of the Shimojishima Airport pilot-training runway, and if the timing matches you can see planes just before landing up close. This is more powerful and interesting than imagined. However, at 17END a vehicle no-entry point was created due to frequent traffic accidents, and you need to walk from there. It's best to check the map in advance.
About 15 minutes by car to Sawada-no-Hama. A natural beach chosen among "Japan's 100 Best Shores," characterised by a distinctive scenery of giant boulders strewn about. These giant boulders were apparently thrown up by the 1771 tsunami. It's famous as a superb sunset spot too, so going in the evening is recommended.
About 15 minutes by car to Nakanoshima Beach. Called "a natural aquarium," it's a popular spot for people who want to enjoy snorkelling. You can see coral reef and vividly coloured fish up close. There are no toilets or shower facilities, so people who value facilities need care.
About 10 minutes by car to Makiyama Observatory. At the highest point on Irabu Island, there's an observatory shaped like a migratory bird called the grey-faced buzzard. You get a sweeping view of Miyako Island, the Irabu Bridge and the clear sea, and on a fine day you can see Ikema Island and Kurima Island too.
About 20 minutes by car to Toriike Pond. A mysterious place where two ponds connect underground, and the sea-side pond further connects to the open sea. A popular spot for divers too.
About 5 minutes by car to Maruki Supermarket. On the ground floor of Hotel South Island, where you can buy ingredients and daily goods. It sells handmade bento too, convenient when you want to eat breakfast in the room.
About 3 minutes by car to Super Minamiha. In the inland part of Sawada-no-Hama, with substantial handmade deli dishes too. It feels like a community-rooted supermarket indispensable to local life.
About 1 minute by car to FamilyMart Miyako Irabu. Irabu Island's only convenience store, open until late at night. When you suddenly need something, this is what you rely on.
The location of about 30 minutes by car from Miyako Airport and about 6 minutes from Shimojishima Airport is convenient for travellers too. Especially if using a flight from Shimojishima Airport, the short travel time is welcome.
Cross the Irabu Bridge and you can get to the main Miyako Island right away too, so access to Miyako Island's sightseeing spots is easy. You can enjoy Miyako Island's famous spots like Yonaha Maehama Beach, Cape Higashi-Henna and Sunayama Beach on a day trip too.
Pros and Cons I Found from Actually Staying
I've written only good points, but honestly there are cons too. I'll write real impressions.
Pros
Good value. A spacious 30 m² room with a washing machine, dryer and mini kitchen, around ¥10,000 a night. A long-stay discount applies too, so if you stay a week or more it becomes quite a deal.
You can park in front of the room, so getting luggage in and out is easy. It's truly convenient for people doing marine sports with lots of wet things, like diving gear.
You don't have to mind check-in and check-out times. Arrive late at night or set off early in the morning, no problem. Being able to move at your own pace is the best.
Privacy is protected. With no cleaning, no one comes into your room. Even on a long stay you don't have to mind it.
Good location. Access to Irabu Island's main sightseeing spots is easy, and supermarkets and a convenience store are close too.
A washing machine and dryer in the room. This is a truly welcome facility for sea-play-focused people. You can do laundry every day, so your luggage stays light.
Simple cooking with the mini kitchen. Convenient when your stomach is tired from continuous eating out, or when you want to eat breakfast in the room.
Close to Shimojishima Airport. For people coming on direct flights from Tokyo or Kansai, the short travel time is nice.
Cons
No staff service. Being an unmanned hotel, the response when something happens is by phone or email. It doesn't suit people who want to talk to a person in real time to solve things.
Some people are anxious about self-check-in. For people not used to tablet operation or bad with machines, the barrier might be a bit high at first.
No cleaning. Towel changes and amenity refills require going to the library space yourself. It doesn't suit people who want daily cleaning.
Being a motel-type build, you can sometimes hear the next room. There were voices in reviews too like "I minded the next room's sound." People who want a quiet environment need care.
The breakfast-venue guidance is insufficient. There was a voice in reviews like "there was no guidance on the breakfast venue and I had to ask myself." It's safer to check in advance.
The restaurant is closed Mondays. Shokusaitei Mutsumi is closed on Mondays, so if you stay on a Monday you need to find another meal place.
Irabu Island itself is a leisurely island, so some people might feel "there's nothing." It might be boring for people who seek urban stimulation. But conversely, for people who want to spend it quietly and slowly, I think it's the best environment.
Being road-facing, the sound of cars can sometimes bother you. Bringing earplugs might be reassuring.
Who Is It Recommended For?
The people Blue Cove Terrace suits are, I think, these.
People who want to enjoy diving and snorkelling. With a washing machine and dryer in the room, you can wash and dry wet things every day. There's a diving shop nearby too, and access to popular snorkelling spots like Nakanoshima Beach is easy.
People who want a long stay. For people planning to stay a week or more for workation, a migration trial or a sports camp, it's ideal. A long-stay discount applies too, and with a spacious room and a mini kitchen you can spend it comfortably.
People who want to travel at their own pace. You can move without minding check-in and check-out times, and with no cleaning your privacy is protected. For people who want to spend it freely without being disturbed by anyone.
Value-focused people. A spacious room with substantial facilities, around ¥10,000 a night. Stay long and it becomes even more of a deal. Perfect for people who want to spend it comfortably without spending money.
People who don't mind self-service. You need to do towel changes and amenity refills yourself. But for people who feel the high freedom and comfort in return, it suits.
People whose travel is mainly by car. The car park is free and you can park in front of the room. If you plan to rent a car and tour the island, it's very convenient.
Conversely, the people it doesn't suit are these.
People who expect staff support. Being an unmanned hotel, face-to-face support is basically absent. If something happens you respond by phone or email.
People who want daily cleaning. With no cleaning during the stay, it doesn't suit clean freaks who want the room tidied daily.
People bad with machine operation. Self-check-in is tablet operation, so for people not used to machines the barrier might be high.
People who seek a luxury resort experience. Being a casual resort hotel, I think it's lacking for people who expect a luxurious experience.

For a Long Stay on Irabu Island, Blue Cove Terrace Is the Best Answer
Blue Cove Terrace is, I think, quite a good option for people who want to enjoy a long stay or marine activities on Irabu Island. You might be bewildered at first by the unmanned-hotel format, but once you're used to it you'll notice its high freedom and comfort.
A spacious room, washing machine and dryer, mini kitchen, free parking. With these facilities at around ¥10,000 a night, it's honestly too good value. A long-stay discount applies too, so if you plan to stay a week or more, it becomes even more of a deal.
The location is also faultless. 2 minutes by car to Toguchi-no-Hama, 10 minutes to 17END, 6 minutes to Shimojishima Airport. Access to Irabu Island's main sightseeing spots and to the main Miyako Island is easy. Supermarkets and a convenience store are close too, so you won't be stuck for living.
There are cons too. No staff service, no cleaning, self-service being basic. But change your perspective and these are merits too. Disturbed by no one, you can spend it freely at your own pace. Privacy is protected, and you don't have to mind check-in and check-out times.
For people who want a long stay on Irabu Island, people who want to enjoy diving and snorkelling, value-focused people, people who want to travel freely, it's a hotel I can truly recommend. I want you to by all means experience the new format of the unmanned hotel.
