Akashi Kaikyo Bridge: The Longest Suspension Bridge in the World

Standing like a steel ribbon over the Seto Inland Sea, the Akashi Kaikyo Bridge links the bustling city of Kobe with Awaji Island in Hyogo. Completed in 1998, it stunned the world with its record breaking central span and today stands as the world’s longest suspension bridge. It belongs on every Japan must visit list and is perfect for travellers who want sweeping views, engineering wonders, or an easy day trip from Kobe.

The idea for the Akashi Kaikyo Bridge grew from tragic ferry accidents in the busy strait, prompting plans for a safer, year round crossing. Built through the late 20th century, the project mobilised engineers, shipwrights and thousands of workers across Hyogo Prefecture, blending traditional maritime skills with modern civil engineering. Engineered to withstand powerful winds and frequent seismic activity, the Akashi Kaikyo Bridge uses tuned dampers, flexible expansion systems and advanced cable techniques developed with expertise from firms around Kobe.

The Maiko Marine Promenade is a circular network of observatory walkways tucked beneath the bridge deck, sitting about 50 metres above the water and giving you a rare, up close view of the bridge’s structure. From the enclosed platforms you can observe the massive cables and towers, explore hands on displays about seismic and wind resistant design, and watch ships slip through the strait below.

At the Kobe end of the Akashi Kaikyo Bridge, the Bridge Exhibition Center offers clear, visitor friendly displays that explain the planning and construction of the crossing and showcase suspension bridges from around the world.

To see the span in context, visit nearby waterfront parks or take a short ferry for a shoreline viewpoint at dawn or dusk when the light is at its most striking. Sunset in particular turns the steel into a dramatic silhouette, so bring a camera and arrive early for the best golden hour shots.

This engineering landmark is more than a record holder. It is a scenic stage offering breathtaking views and golden hour photo opportunities that draw travellers back. Plan a visit to the promenade or nearby waterfront and let the span’s quiet grandeur be the highlight of your day trip.
