A northern governor permitted a ship carrying 30 tons of nuclear waste to unload its cargo Friday, ending a four-day standoff after the prime minister promised to find some other spot to dump such waste.

Gov. Morio Kimura allowed the Pacific Swan, completing a two-month journey from France, to dock after Prime Minister Ryutaro Hashimoto offered assurances the waste would be moved from the seaside village of Rokkasho, 325 miles from Tokyo.Kimura allowed the ship to enter port so its 26 crew members could rest and escape rough seas. After meeting with Hashimoto in Tokyo Friday, Kimura also gave the go-ahead for the Britsh-flagged ship to unload its cargo.
