In addition to hot springs, Japan is a hot spring country. I don't need to say more about the famous hot springs, but in addition to hot springs, Japan has Sakai Cangdong! niche attractions, natural ghosts and craftsmanship are natural masterpieces, go to enjoy the fine carvings of nature. I'm already amazed that I'm standing on a 240-meter cliff, a bell-milk hole made of limestone washed with running water. There are no caves in the ground, countless stalactites, different shapes, are given a variety of names and meanings, to carefully observe and imagine, chat with companions, will find that everyone's angle is different, see the shape is also different, so interesting! And with the light at the bottom of the hole, people are amazing. The geological landscape here also attracts many geologists to explore. Here is my little guide! Address: 409 Xinjian City, Okayama County Tel: 81-867-75-2224 Transportation: Take JR from "Bobei Line" to "Ii Cangyu". Open time: 8:30~17:00 (rainy season may be necessary, sometimes floods will flood the surrounding Ii Cangdong), humanized reminder: It will take about 40 minutes to visit the entire Ii Cangdong, which is still very tired. There is a special short tour route in the cave. People with inconvenient legs and lazy friends should not let go of this natural carved beauty. Finally, I want to say that Ii Cangdong is great value, hurry up and punch in!
