In mathematics, the lakes of Wada (和田の湖, Wada no mizuumi?) are three disjoint connected open sets of the plane with the counterintuitive property that they all have the same boundary.
More than two sets with the same boundary are said to have the Wada property; examples include Wada basins in dynamical systems.
The lakes of Wada were introduced by Kunizō Yoneyama (1917), who credited the discovery to his teacher Takeo Wada.

Famous quotes containing the word lakes:
“When you get out on one of those lakes in a canoe like this, you do not forget that you are completely at the mercy of the wind, and a fickle power it is. The playful waves may at any time become too rude for you in their sport, and play right over you.”
—Henry David Thoreau (1817–1862)
