Overview (history, characteristics, attractions)
Umihotaru is an offshore parking area and tourist facility located at the midpoint of the Tokyo Bay Aqua-Line. It began operation in 1997 (Heisei 9), when the Tokyo Bay Aqua-Line opened. Its major attractions are its appearance like an island floating alone on the sea, 360-degree ocean views, Tokyo Bay, the cityscapes of Tokyo, Kawasaki, and Chiba, and, on a clear day, even Mount Fuji. Equipped with restaurants, souvenir shops, an observation deck, and more, it is popular not only as a rest stop for drivers but also as a tourist spot.
Highlights
- Observation Deck: The rooftop and observation spaces on each floor offer a panoramic view of Tokyo Bay. The view from dusk to night is particularly beautiful, making it a popular photo spot.
- Food and Drink: There are restaurants and food courts specializing in seafood, where you can enjoy a meal while looking out at the sea. The restaurants change frequently, so it's a good idea to check the latest information before visiting.
- Souvenirs and Shopping: There are many souvenir shops selling local seafood and local sweets. You can do some quick and easy shopping here.
- Outdoor walking area: There are walkways and benches where you can feel the sea breeze and relax. Please bring warm clothes on windy days and during the cold season.
