In Okamura Island, a hotel must provide a certain amount of upscale conveniences to be designated 5 stars. These can include on-site gyms, spas and saunas, gourmet restaurants, premium bedding, luxury bathroom products and more. What also sets 5-star hotels apart is their extraordinary standard of service. You can expect things like concierge services, nightly turn-down services and in-room massage. Some may even offer additional touches like welcome gifts.
