Tōrō nagashi: seeing the dead off by lantern
On the last evening of Obon, Japanese families write their ancestors' names on paper lanterns, light them, and set them on the river to carry the spirits home. On the festival's gentlest hour, and why the send-off matters as much as the welcome.Written to last.

Obon begins with fire that says come home: lamps at the gate, fires on the hillsides, lights to guide the ancestors back to the house for their August visit. Three days later it has to solve the harder problem. The visit ends. The dead must be seen off.
The answer, in towns along rivers and coasts across Japan, is tōrō nagashi: the floating of the lanterns. At dusk on the festival's last evening, families come to the water with paper lanterns, a candle inside each, the family name or a message to a particular person brushed on the paper. They light them, set them on the current, and watch. Hundreds, sometimes thousands of small flames drift downstream together, around the bend, toward the sea, until the river is a slow procession of light carrying the summer's guests away.
Almost everything in the rite is direction. The welcoming fires of Obon's first night burn at the house, fixed points saying here; the lanterns of the last night move, and move away, downstream, seaward, in the direction rivers have always stood for. Nobody retrieves a lantern. The whole point is that it goes, taking its passenger with it, and that the family stands still on the bank as it does, which makes tōrō nagashi one of the very few remembrance customs whose whole content is letting go, performed annually, gently, with the entire town letting go at once.
The dead, in this tradition, are not being dismissed. They are being seen to the door. They will be back next August, and the lanterns will be lit again, both facts known to everyone on the bank, which is what keeps the evening tender rather than bleak. Grief with a return ticket.
The custom carries one of Japan's heaviest anniversaries. Each 6 August, on the Motoyasu River that runs past the Atomic Bomb Dome in Hiroshima, thousands of lanterns are floated for the dead of 1945, many inscribed with names, many with messages written by schoolchildren to people they never met. The same vessel, the candle in paper on moving water, holds a family's grandmother and a city's hundred thousand dead without changing its design, which is a fair measure of how much load a simple form can bear.
The form travels well. Lantern floatings in the tōrō nagashi line are now held from Honolulu, where tens of thousands gather each Memorial Day, to riversides across Asia and beyond, most of the participants far from any Buddhist framework, all of them recognisably doing the same thing: giving a name to a light and letting the water take it.
A lantern bears a name, a candle, and at most a sentence, and by morning it is gone; it is the least permanent memorial in this entire library, more fleeting even than the meadow grave, and deliberately so. Its work is done in the two minutes the family watches it go. The permanence lives elsewhere, in the butsudan at home, in the household's stories, in whoever keeps the names that get brushed onto the paper each August.
Which is the quiet dependency under the loveliest evening of the Japanese year: someone has to still know the names. The lantern is written from the family's memory, not the other way round, and a family that keeps that memory recorded, in a place like Confinity, is stocking every future August with passengers. The river does the sending. The record makes sure there is someone to send.
