From July 18 to August 31, five planes dressed in “pocari blue” will launch the outsized “POCARI SWEAT” cloud advertisement 600 times in the sky over Japan. In this advertisement, the words are 4.5 KM in width from right to left, with every one 400 m*400 m in size, equivalent to about four domes of Tokyo. The flight team undertaking this promotion activity ever carried out the sky advertising of “Five-circle” and “WELCOME” marks at 1984 Olympic Games in Los Angeles, US, thus shook the whole world.
