Izu Oshima Hotel & Resort Mashio
Tokyo Metropolis/Izu OshimaPerched on a hill overlooking the tidal currents. All three rooms offer ocean views.
Surrounded by the chirping of birds and overlooking the currents from a high vantage point, Izu Oshima Hotel & Resort Mashio. Untouched nature orchestrates the transitions of the four seasons. We look forward to welcoming you with a comfortable space and warm hospitality.
This Hotel is located at the top of a narrow mountain road. It was very quiet, and the soothing music playing throughout the Hotel made it even more relaxing. Unfortunately, it was cloudy, but if there hadn’t been any fog, we would have been able to see the horizon from our Room and enjoy an even more wonderful view. The meals were carefully prepared, and both the fish and roast beef were served with vegetables that paired perfectly with each dish—everything was delicious. The dessert was a yogurt mousse (I’m not sure if that’s correct), but it was excellent.We stayed as a family of four, including our son in his 20s, and everyone left feeling full—though we did ask for extra bread. We were told they host only three groups per day, and we were able to use the spacious private family bath as well. It was a stay that freed us from everyday busyness and truly felt like an escape. The interior furnishings throughout the Hotel were also thoughtfully arranged and had an elegant feel. If we have the chance, we would love to visit again. Thank you very much.
いぶりっち 3/31/2026We stayed here to celebrate my 93-year-old mother's birthday. Although the location was a bit hard to find and we got lost in the mountains, we were relieved when someone came to pick us up and safely guided us to the accommodation. The guest room was like a private space with high ceilings and beautiful views, which was truly wonderful. The meals were delicious, made with fresh ingredients that brought out their natural flavors, and both my mother and husband praised them highly. Although the weather wasn't perfect, Masio-san's hospitality more than made up for it. This is one of the rare accommodations that makes you want to visit again.One small suggestion: it would be helpful if water could be placed on the table during meals so guests can serve themselves at any time.
