Jutting over a still harbour on weathered timber pilings, a broad wooden dock leads the eye to a striking three-storey Western-style concrete hotel — its balconies dressed with bold Japanese kanji banners proclaiming "江の島海岸温泉 / 岩本楼別館," the celebrated Enoshima Seaside Hot Spring establishment at Iwamoto-rō. This atmospheric real-photo-style sepia postcard captures the hotel complex at the height of its Taishō-era popularity, when Enoshima — a small island near Kamakura south of Tokyo — was Japan's premier seaside resort destination. A traditional multi-roof Japanese structure flanks the modern building to the right, neatly illustrating the architectural collision of Meiji modernisation. Small boats are moored beneath the dock, their hulls barely visible in the dark water below, while painted advertisements cover the retaining wall in sweeping brushstroke kanji. The lower left carries the telephone/postcard catalogue number 電話片通三二八番, placing production with a commercial studio circa 1910–1920. The reverse bears "CARTE POSTALE / UNION POSTALE UNIVERSELLE" and a vertical Japanese inscription.
