We took the JR train back to Kobe, where we had booked accommodation. The train line runs close to the coast and at one point the Akashi Kaikyo bridge is clearly visible. The Akashi Kaikyo is the longest span bridge in the world at a whopping 3.91km. It goes from Hyogo prefecture on Honshu island across to Awaji shima (island) and connects via expressay to a bridge on the other side of Awaji to Shikoku Island, the smallest of Japan's four main islands. The photo leaves a bit to be desired, but it gives an idea of the expanse.
