O-bon Fire Ritual: Flames Across Hillsides, a Countryside Summer Tradition

About this spot

A traditional O-bon ritual passed down in Tomioka's Oshima district to guide ancestral spirits. Fires are lit simultaneously on hillsides overlooking the settlement, creating a solemn and beautiful sight where flames connect across the darkness—a quiet beauty unlike urban fireworks. Though modest in scale, this community-maintained tradition is cherished as a vital summer event in the local calendar.
