Akashi Kaikyo Bridge, as seen from Awaji Island

After billions of dollars in construction works, the Seto Inland Sea is now crossed by no less than three stupendously huge bridges. From east to west:

  • Akashi Kaikyo Bridge, with the longest suspended span in the world, between Akashi (off Kobe, Honshu) and Awaji
  • Seto-Ohashi Bridge, a set of six bridges connected Okayama (Honshu) to Kagawa (Shikoku)
  • Shimanami Kaido, from Hiroshima (Honshu) to Ehime (Shikoku)

By train

The only train connection across the Inland Sea is via the Seto-Ohashi Bridge from Okayama to Takamatsu and onward. Services are fast and frequent, although no Shinkansen service is available.
