Have you ever dream of floating in the water without exerting too much effort, even if you didn’t have any swimming experience? If you want to turn that dream into reality, you should try visiting the public pools in China and Japan. China’s Dead Sea is the largest indoor water park resort in Daying district in Sichuan province of China and Tokyo Summerland is a popular water park that’s home to the world’s most crowded wave pool. These two are the most crowded swimming pools in the world.
DEAD SEA OF CHINA
Inspired by the original Dead Sea in the Middle East, the Dead Sea of China resort is situated at the same 30 degree north latitude and features architecture decorated with sculpted camels and supported by Greco-Roman columns. The “sea” itself which is actually a gigantic swimming pool – is housed beneath a translucent semi-cylindrical dome that lets in just enough sunlight to keep the fronds of the many transplanted palm trees green. Its construction is based on Daying’s rich deposits of bittern, a by-product of the salt-making process.
With an investment of 1 billion yuan (US$121 million) and an area of 133 hectares, the project consists of a four-star hotel, indoor and outdoor heated swimming pools, bowling and basketball courts.
According to Sichuan Geological Survey, China’s Dead Sea natural bittern water is mainly composed of sodium chloride (table salt), and it also have 40 kinds of mineral substance and microelement in its water. The predominant elements are potassium, iodine, bromine, calcium, etc. The main difference between the typical hot spring and the bittern water of the Dead Sea is there is ionic forms salin in the water of the latter. It consist of carbonate, sulphate, magnetic salt, oxonium salt, calcium salt, sylvite, alumina, iron oxide, bromine, silica, etc. Based on modern medicine, these substances are of very essential for the improvement and accommodation of human health and that’s the root why Dead Sea is of high value in health care.
Crowded pools are also common in Japan. National Geographic photographer Michael Yamashita, who captured pictures of a typical summer day at one of the largest waterpark, the Tokyo Summerland, told My Modern Met:
“There’s no question that given the heat, humidity and population of Tokyo in the summer, the throngs at any swimming pool there are going to, by definition, test the limits of crowd control and sanitation. Japan, however, is prepared for this and manages to keep everyone happy and cool no matter how jam-packed the pool – by moving the water rather than the swimmers. While not exactly conducive to laps, giant wave pools surge with swells a meter or higher, drenching stationary bathers so they don’t need to swim to cool off. Other pools feature circular courses with a current that keeps everyone moving together in the same, very orderly, direction. And of course, Japanese people, by tradition and habit, are arguably the cleanest – not to mention the most cleanliness-conscious – in the world. The water in these pools is clean enough to drink!”
