Relatives commemorated Thursday the 36th anniversary of the Japan Airlines crash that claimed the lives of 520 crew and passengers in the world's deadliest single-aircraft accident.

Members of bereaved families climbed the steep mountain trail to the Boeing 747's crash site on Osutaka Ridge in Gunma Prefecture. Participants were restricted mostly to kin for the second year amid the coronavirus pandemic.

Shortly before 7 a.m., the bereaved family members, many of whom were elderly, started walking toward the ridge.
