Umihotaru PA Tokyo Bay – Breathtaking Views & Unexpected JDM Encounters
Umihotaru Parking Area（Umihotaru PA Tokyo） is not just a highway rest stop—it's a floating oasis in the middle of Tokyo Bay. Located on the Tokyo Bay Aqua-Line expressway, this one-of-a-kind PA offers panoramic ocean views, shopping, dining, and even the occasional JDM car meet on its top deck.
🌊Floating Above the Sea
Half bridge, half tunnel, the Tokyo Bay Aqua-Line connects Kawasaki and Kisarazu. Right in the middle sits Umihotaru PA—a man-made island built for travelers to relax and recharge while surrounded by ocean on all sides. You’ll get 360-degree views of the bay, Rainbow Bridge, and even Mount Fuji on a clear day.
It’s especially popular during sunsets and night drives, making it a favorite destination for both tourists and car lovers looking to cool down after a spirited highway cruise.
🚘A Surprise JDM Spot
Although not officially known as a JDM hotspot like Daikoku or Tatsumi, Umihotaru has become a spontaneous meet-up spot. Especially on weekends or national holidays, it's not unusual to see lines of GT-Rs, Supras, RX-7s, and tuned imports lining the outer deck. The unique lighting and sea backdrop also make it a favorite among car photographers.
Plus, the multi-level structure means there’s always a place to chill, eat, and take in the view—even if the top lot is full.
📍How to Get There
Umihotaru PA is only accessible via the Tokyo Bay Aqua-Line Expressway. You can enter from either the Kawasaki side (Kanagawa Prefecture) or Kisarazu side (Chiba Prefecture). A toll is required, but the drive itself—especially through the underwater tunnel—is part of the adventure.
📸Best Times to Visit
Golden hour (just before sunset) offers unbeatable photo ops, but after 9 PM is when the JDM cars start to roll in. Bring a tripod, a warm jacket, and your best lenses—Umihotaru is pure magic under the stars.
🏁Final Thoughts
Umihotaru PA isn’t just a stop—it’s a destination. From the surreal experience of driving under the sea to the elevated vibes of ocean air, this PA brings together the best of Tokyo’s tech, nature, and car culture. Whether you're a tourist, tuner, or just out for a drive—Umihotaru is worth every toll yen.
