The death toll from a tropical storm buffeting Japan rose Thursday to 15 after searchers found more victims, including two men buried inside their homes beneath mud and debris that had barreled down a mountainside. Tropical storm Meari has cut a wide swath through Japan since Sunday, causing floods, triggering deadly landslides and forcing about 10,000 people to flee their homes for shelters. Twelve people were missing and at least 70 others had been injured.
