Details on the Fukitsugi River Tidal Flat
The Fukitsugi River Tidal Flat is a tidal flat that appears near the mouth of the Fukitsugi River at low tide; the area is also home to natural mangrove forests and serves as a habitat for many species.
When they are visible, you can spot creatures such as crabs and gobies, as well as crab burrows.
In addition, at low tide, when the mudflats are exposed, you can see the full extent of the mangrove roots and take your time observing species such as the Yaeyama mangrove, with its unusual, octopus-like roots, and the black mangrove, with its knee-shaped roots.
Since the types of mangrove plants vary depending on the salinity of the water, be sure to enjoy observing the changes in the vegetation when you take part in a canoeing or SUP tour.
When the tidal flats are exposed, you can see lots of crab burrows and small, dumpling-like objects.
These dumpling-like things are left behind after crabs filter out organic matter to feed on, so if you look around here, you'll be able to find some crabs.
At low tide, you can walk across the mudflats to go quite far, so be sure to visit during low tide.

Because they tend to form groups, they are called "army crabs."
