An unforgettable escape: breathtaking views you’ve never seen, a coastal drive in a Rolls-Royce convertible, and the inspiring fusion of skin-beautifying Onsen and Mirabath.

Have you ever been moved to tears at an Onsen Ryokan? XYZ Speciale offers an overwhelming escape from the ordinary—and your greatest memories. “True, unobstructed views” 펼—an endless world of sea and sky with no man-made structures in sight. Share the “best starry sky of your life” with someone special. A coastal drive in a Rolls-Royce convertible is especially recommended in the coming season and has been highly praised as the “ultimate extraordinary experience.” In addition to the open-air bath with spectacular views, we have now installed in-room bathing innovations featured at Expo events—the futuristic “human washing machine,” Mirabath, and Mirable—in every Room. Enjoy breathtaking scenery in the open-air bath and skin-beautifying benefits in the indoor bath, making the most of Tsubaki Onsen—often compared to a facial lotion—in two distinct ways. Our Guinness-recognized laser message has brought many guests to tears and is XYZ’s one-of-a-kind original service that creates unforgettable memories. Enjoy a new style of Onsen stay—precious time with someone special, spent in an exquisite private space. - A new style of in-room dining - Meals are served in a private, dedicated dining area within your Room, so staff do not enter your private space. Savor creative cuisine alongside ever-changing “magic hour” views from sunset onward. - True panoramic views “Real Infinito” - From your Room, enjoy scenery on par with famous Pacific Ocean viewpoints: 240° of uninterrupted sea and sky, a gracefully curved horizon, and a cliffside seat where only the sound of waves surrounds you—an awe-inspiring panorama that lets you feel the roundness of the Earth. - Advanced beauty amenities for radiant skin - All 12 Rooms are standalone villas. In your open-air bath with an electric retractable roof, indulge in 100% natural hot spring water from Tsubaki Onsen. We also provide “Mirabath & Mirable ZERO” and the latest ReFa hair dryer. Cutting-edge beauty technology helps leave your skin smooth and supple. - A breathtaking night view that stirs the soul - At night—when all lights are turned off—a different world unfolds. A sky filled with stars, the Milky Way, shooting stars, moonlit seas, and a fantastical nightscape. Staying at XYZ is a rare extraordinary experience: spending one night on a secluded coastline. Enjoy one-of-a-kind miraculous ocean views that transform moment by moment. Spectacular views, Onsen baths, gourmet cuisine—and deep emotion. All yours exclusively within your Room. We offer an Onsen stay unlike anything you have experienced before. “Beyond infinity.” Discover true scenery through fully private luxury.

  • Everything was wonderful. Every dish we had was delicious. My husband, who rarely gives compliments, kept saying how good it was, and I was so happy to be able to enjoy the meal together with him. And the Onsen left my skin silky smooth—while soaking, it felt as if my whole body were being bathed in lotion, and even after getting out of the water there was no tightness at all. Normally I need to apply body cream or my skin feels tight, but this time it stayed moisturized even without it. There was also a Mirable bath, and I was glad to have that first-time experience. After dinner, a laser message display appeared, and I was truly moved when I saw my family’s message. And with the breathtaking star-filled sky that felt like it might fall from above at night, plus the spectacular daytime views stretching all the way to the horizon, everything felt extraordinary—I’m really glad we stayed here. All of the staff were very kind and created a warm, homey atmosphere, so we were able to relax and take our time. Thank you very much for taking such great care of us during our stay. It’s a Hotel where we would definitely like to stay again.

  • I used this Accommodation to propose to my girlfriend. She was truly moved by the laser surprise and how wonderful the Room was, and the surprise went perfectly. The staff were also excellent, and it was a huge help that they even confirmed the surprise arrangements with me. Everything was fantastic with nothing to complain about; the only disappointment was that the bed was quite firm and I couldn’t sleep well. Still, even without much sleep, soaking in the Onsen while gazing at the moon and stars made it a very fulfilling stay. We said we’d like to stay here again on our wedding anniversary.\nThank you again, and we look forward to coming back.

Notice from the Accommodation

  • [Ultimate Skin-Beautifying Benefits] The “Mirable Bath” Human Washing Machine Has Been Installed!

    A deeply moving laser message service that brings many guests to tears.
    Following the ultimate escape: a highly acclaimed seaside drive in a Rolls-Royce convertible…

    For the third installment of XYZ’s Speciale services, we are taking on the pinnacle of skin-beautifying Onsen by installing microbubble bathing systems in every guest room.

    “Mirable Bath” is a state-of-the-art bathing system that generates ultra-fine bubbles (microbubbles), drawing attention as part of the futuristic “human washing machine” concept at Expo 2025 Osaka.

    By combining our renowned “beautifying waters,” Tsubaki Onsen (100% natural spring water), with Mirable Bath technology, we offer an unprecedented skin-enhancing experience.

    When microbubbles’ cleansing and skincare benefits are added to Tsubaki Onsen’s highly alkaline, naturally silky water—often likened to a natural lotion—you can enjoy the finest skin-beautifying Onsen experience.

    We promise a refreshing stay for both body and mind with an Onsen-focused retreat you won’t find anywhere else—featuring Japan’s first electrically opening-and-closing open-air bath with breathtaking views, along with an indoor bath equipped with cutting-edge technology.

  • Terrace Dining in Guest Rooms

    Dinner at the Terrace Dining Room

    For a while, as part of our insect prevention measures, we had been serving dinner in the anteroom dining Room in front of your Room, which may have caused inconvenience. Starting today, we will resume serving dinner in the terrace dining room, where you can enjoy the evening view.

    XYZ Speciale will continue to help make your special moments even more memorable.
    We sincerely look forward to welcoming you.

  • "XYZ Real Infinite"

    A quiet escape from the crowds—time spent simply facing the sea. Our Accommodation stands on dramatic seaside cliffs and offers 12 guest rooms, each with a private terrace and an open-air bath.

    You often hear terms like “ocean view” or “infinity.” Yet in many cases, man-made structures still come into sight between you and the water.

    To clearly distinguish this from views that merely overlook the sea, we describe it as a “real infinity” experience.

    Where sky meets the curved horizon, a sweeping Pacific panorama reveals the roundness of the Earth. With no artificial structures to block your view, all you hear is the rhythm of waves rolling in and out. It’s a luxurious space that feels like having scenery beyond any famous viewpoint entirely to yourself.

    Feel the sea breeze on your terrace and soak in Onsen in your open-air bath. Watch the ocean change moment by moment and enjoy an evening sky painted by sunset all to yourself. This authentic ocean-view experience—“XYZ Real Infinity”—deeply restores both body and mind.

    Forget everyday noise and savor blissful moments at one with nature—fully at your leisure at our Accommodation.
