About 200 people in some 120 households in Tokushima Prefecture remained isolated Monday night as roads blocked by fallen trees and snow after heavy weekend snow had yet to be cleared.
About 170 personnel from the Ground Self-Defense Force continued work to clear roads leading to an area covering the city of Miyoshi and the towns of Tsurugi and Higashimiyoshi.
Heavy snowfall over the weekend left at least seven people dead and hundreds cut off, authorities said.
