Shio Senkyo no Riku

One of the natural wonders of Rokugan.

Also known as Tidal Landbridge.

At low tide it sits uncovered by the water, forming a landbridge almost half a mile wide. But at high tide the landbridge is completely submerged in water.

There has been an ongoing dispute between the Crab and Crane about who owns it. There is a garrison of Daidoji on the eastern side of the landbridge, registering anyone who crosses.
