岡田港船客待合所

Ground-floor transit operations—centered on the Tokai Kisen counter and primary waiting lounge—give way upstairs to a community-run specialty area and souvenir shop. The second level houses 10 permanent optical illusion installations themed around Izu Oshima's stratified cliff sections and volcanic events. Outside, an exterior rear staircase provides direct access to the upper floor, offering a quiet vantage point to watch the sunrise across the water.
