International Fountain

[3] From the beginning, we have set about this fountain design with a view to putting sole stress upon water itself — its shape and movement — without recourse to any sculpture or accessories.

Furthermore lively feeling can be expressed in the swelling curved phases of water by opening and shutting nozzle cocks at different time lag.

Such beauty and might are expressed only by means of water, which may be called, in its true sense of the work, a fountain.The competition received 261 entries, of which 72 were international and 189 came from the United States.

[5]: 11  The jury, which consisted of noted architects and sculptors Nathaniel A. Owings, Bernard Rosenthal, Garrett Eckbo, Peter Oberlander, Paul Thiry, and Fred McCoy, selected Matsushita and Shimizu unanimously from the five finalists.

"[4]: 8–9  At the time of selection, Matsushita was 29 and Shimizu was 26, and both were employed as associate architects with Taisei Construction Company in Tokyo.

[2][6][7] Prior to 1995, the central dome had protruding nozzles and was surrounded by irregular white rocks to recreate a "lunar landscape",[8] discouraging people from interacting with the water features.

In this photograph, the "super shooters" installed by WET Design in 1995 are in operation and the water jets are reaching their peak height of approximately 120 feet (37 m). The ground level perspective creates an illusion the jet is nearly as tall as the Space Needle, shown in the background.
