Join us on an unforgettable journey under the sea and through the sky! On this adventure, we explore two engineering marvels in Japan: Tokyo Bay Aqua-Line (Trans-Tokyo Bay Highway) – a 23.7 km expressway weaving together a 9.6 km underwater tunnel and a 4.4 km bridge, connecting Kawasaki (Kanagawa) and Kisarazu (Chiba). You’ll travel through the undersea “Aqua Tunnel,” step onto the unique Umihotaru artificial island—complete with restaurants, observation decks, and the iconic “Tower of Wind” (Kaze no Tō) ventilation tower—and witness the gargantuan shield tunneling machines that made it possible. Chiba Urban Monorail – the world’s longest suspended monorail system, spanning 15.2 km across two lines with 18 stations. It glides gracefully over residential roads and busy cityscapes, offering unmatched views and a ride that feels like a gentle upside-down roller coaster. We take you riding on this futuristic “sky train,” capturing the sleek efficiency and pristine cleanliness typical of Japanese public transport. Chiba Station buzzes below, while the suspended monorail hums above—showcasing how modern infrastructure meets urban life.
