A Japanese worker was electrocuted today while helping to remove the 1,340 blue parasols arrayed in a Japanese valley by the environmental artist Christo, the police said.

The worker, Masaaki Nakamura, 51 years old, was operating a crane when the machine's arm touched a 65,000-volt high-tension line about 25 feet above the ground, said an official of the Hitachi Ota police.

It was the second death resulting from Christo's two-nation umbrella art project. Last Saturday, high winds blew an umbrella across a road at the project's other site, the Tejon Pass in California, and crushed a 33-year-old woman against a boulder.
