Relatives on Wednesday commemorated the 35th anniversary of the Japan Airlines jetliner crash that killed 520 passengers and crew 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 to mourn their loved ones. The annual trek was spread over a few days this year, with participation restricted mostly to kin to prevent the spread of the novel coronavirus.

The trail was damaged by a typhoon last year but has been sufficiently restored to allow access to the crash site.
