Umihotaru is a remarkable rest stop built on an artificial island in Tokyo Bay, Japan. Located along the Tokyo Bay Aqua-Line, it offers drivers a place to pause between Kawasaki and Kisarazu. Its name means “sea firefly,” and the facility’s ship-like design reflects its setting above the water. Visitors can enjoy wide bay views, restaurants, shops, and observation decks, often watching ships cross the harbor or the city lights appear at dusk. Umihotaru is a destination where engineering, travel, and scenery meet above the bay for travelers from both cities.
