Arcana Izu

A private hot tub fed by natural spring water sits on every balcony, which tells you something about the philosophy here. This Michelin Key-holding inn on the Izu Peninsula blends ryokan tradition with international boutique sensibility, the furniture by Osaka designers Graf, the walls of glass framing uninterrupted forest. The 32-seat French restaurant seats everyone facing outward, like a cinema where the film never changes. Two hours from Tokyo, no children under 12.
