Sumiko IV was the fourth planet in its star system. This planet was home to the Cliffs of Heaven and an Emerald Wading Pool. The Cliffs of Heaven were recreated in Holodeck Program 47-C aboard the USS Enterprise-D. In 2368, Kristin was injured twice while diving from the cliffs on Sumiko IV. (TNG: "Conundrum" ) A simulation of the Emerald Wading Pool on Sumiko III was also available aboard the USS Enterprise-E in 2373. (Star Trek: First Contact)
