size of the mangrove growing area in Iriomote Island is larger than any other place in Japan, and almost all species of mangroves that grow in Japan can be seen.<br \/>\nFor example, the Nakama River watershed running south of Iriomote Island is said to have about 25% of Japan's mangrove area, making it the largest mangrove watershed area in Japan.<br \/>\nMangroves grow near the mouths of most of the 40 or so rivers, large and small.<br \/>\nThus, Iriomote Island is the best place to enjoy mangroves in Japan.<\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\"

approximately 2,100 km.<br \/>\nEven from the main island of Okinawa, which is about 400 km away, the island is very close to Taiwan and is about 100 km east of Taiwan.<br \/>\nGeographically, it is 24 degrees north latitude and 123 degrees east longitude.<br \/>\nTo get to Iriomote Island, you can take a boat from Ishigaki Island.<br \/>\nThere are two ports on Iriomote Island, and the journey

mangroves are, their ecology, and what kinds of mangroves grow on Iriomote Island.<br \/>\nIn fact, there is no plant species named mangrove.<br \/>\nMangroves are a general term for plants that grow in salt marshes where freshwater and seawater mix, such as on the coasts and at the mouths of rivers in tropical and subtropical regions.<br \/>\nMangroves grow in what is called the intertidal zone.<br \/>\nThe intertidal zone is the area affected by the ebb and flow of the tide.<br \/>\nIn other words, at high tide, the area is hidden by the sea surface, and at low tide, the area is not submerged in sea water.<br \/>\nBecause it grows in these locations, it appears to grow in the ocean at high tide.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-6007

height=\"480\" \/><br \/>\nThe mangroves of Iriomote Island grow in the area between coral reefs formed in shallow water and plants growing completely on land, and together with coral reefs, they play an important role in shaping the ecosystem of Iriomote Island.<br \/>\nFor example, at high tide, small fish can be seen congregating near the roots of the mangroves, providing a much-needed place for the creatures to gather on the roots.<br \/>\nThe number of mangrove species growing in the world has not been fully determined, but it is estimated that there are approximately 110.<\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"%E6%A0%B9%E3%81%8C%E7%89%B9%E5%BE%B4%E7%9A%84\"><\/span>Roots are distinctive<span
