The red lantern hanging under the Thunder Gate at Sensō-ji is 3.9 metres tall and weighs 700 kilograms. Several times a year, for the Sanja Matsuri and other festivals, the temple staff fold it up like a concertina so that tall objects can pass beneath the gate.
That is the entire idea of a chōchin in one gesture. It is a paper lantern built around a spiral of split bamboo, and its defining property is not that it gives light. It is that it collapses.

A Lantern Engineered to Fold Flat
A chōchin (提灯) is a Japanese paper lantern made from a spiralled bamboo frame covered in washi, the paper produced from the inner bark of the mulberry. The name is written with the characters for carry and light: a lamp you take with you. Its ancestor arrived from China around the sixteenth century, and the collapsible version is the Japanese contribution.
One strip of bamboo, wound in a spiral
Look inside a chōchin and you will not find a series of hoops. You will find a single continuous strip of split bamboo, wound in a spiral from the bottom ring to the top. That spiral is the mechanism. It has spring in it, and it lets the whole body compress into the space between the two wooden rings at either end.
The paper is glued to the outside of that skeleton over a sectional wooden mould, which is then dismantled and pulled out through the opening once the glue is dry. The lantern is essentially a moulded object with no mould left inside it.
Why collapsibility mattered
Before electricity, a lantern was equipment. A traveller carried one, a night watchman carried one, a shop hung one out at dusk and took it in at closing. Something you carry needs to fold, and something a merchant hangs out daily needs to be stored flat for the other twenty hours.
The practical requirement produced an object with no fixed volume — a thing that is a sphere when lit and a disc when it is not. That is a rare property in furniture of any culture, and it explains why the format survived long after the candle inside it stopped being necessary.
The Writing Is the Whole Point
Every serious chōchin carries characters, and almost none of them are decorative.
A lantern outside a bar carries the name of the bar. A lantern at a shrine carries the name of the person or company who paid for it. A lantern at a festival carries the name of the neighbourhood association fielding the float. A lantern in a noodle shop may carry a single word — rāmen, oden, sushi — because that is all a passer-by needs at eye level in the dark.
The characters are brushed on by hand, by a specialist, usually in a heavy vernacular style closer to sign-painting than to calligraphy. The most common lettering styles are built to be read at speed and from below, with thick strokes that survive the curvature of the paper and the flicker of the light behind it.
The red lantern means one specific thing
A plain red chōchin outside a small establishment is a signal every Japanese adult reads instantly. Akachōchin, red lantern, is the ordinary word for the kind of no-frills, loud, smoky drinking place where grilled skewers arrive on the counter and nobody books a table. The lantern is not advertising the bar. It is the category.
This is worth stating plainly, because most writing about paper lanterns treats them as ambience. They are not. A chōchin is a signboard that happens to glow, and it is one of the oldest continuously used forms of outdoor advertising anywhere. Understanding the symbols and characters painted on them turns a row of pretty lights into a street directory.
The donor's name
At shrines and temples, the rows of lanterns flanking an approach are a subscription list. Each one records a donation, and the size and position reflect the sum. Walking that avenue at night, a visitor is reading, without realising it, the ledger of who funded the place — which local business, which family, which company. The light is the receipt.
The Giant at the Thunder Gate
The most photographed lantern in Japan hangs at the Kaminarimon, the outer gate of Sensō-ji in Asakusa. It measures 3.9 metres tall and 3.3 metres across, and it weighs around 700 kilograms.
The front reads Kaminarimon (雷門), Thunder Gate. The back carries the gate's official name, Fūraijinmon (風雷神門), the gate of the wind and thunder gods — a reference to the two statues standing on either side, Fūjin with his wind bag and Raijin with his ring of drums. On the underside, invisible unless you stand directly beneath it and look up, is a carved wooden dragon.
The gate itself burned down in 1865 and stood in ruins for ninety-five years. It was rebuilt in 1960 with a donation from Kōnosuke Matsushita, founder of the company now called Panasonic, and the metal base of the lantern carries a plate bearing the old company name. The lantern is replaced roughly every ten years, each one hand-built.
And several times a year, it is folded. During the Sanja Matsuri and similar events, the 700-kilogram lantern concertinas upward so that portable shrines and tall floats can pass through the gate. The largest chōchin in the country obeys the same rule as the smallest.
It sits within a much larger architectural vocabulary worth reading before a visit; our guide to Japanese temples covers the gates, halls and pagodas these lanterns hang from.
The Families of Chōchin
The word covers a range of shapes, and the differences are functional rather than stylistic.
Odawara-chōchin
The travelling type: cylindrical, plain, with a flat top and bottom that let it fold down to almost nothing. It takes its name from the post town on the Tōkaidō road and was carried by anyone walking between cities at night. This is the ancestor of every folding lantern that followed.
Bonbori
Rounder and squatter, with a wide shade, often mounted on a pole or a stand. Bonbori are the lanterns of the Hina Matsuri doll display and of shrine paths at dusk. They are made for softness rather than for reading.
Takahari-chōchin
The tall pole-mounted type used at festivals and at funerals, raised high enough to be seen across a crowd or a field. When a village needed to signal a gathering point in the dark, this was the instrument.
Bon-chōchin
The lantern of the dead, and the one with the most weight attached to it. Often decorated with painted flowers or fitted with a revolving inner shade that turns with the rising heat, casting moving shapes on the paper.
Obon: The Lanterns That Are Not Decoration
For three days in mid-August, Japanese households mark Obon, when the dead are held to return to their families.
The chōchin has a job in this. A mukaebi, a welcoming fire, is lit at the start so that the returning spirits can find the house; a okuribi, a sending-off fire, closes the festival. Where an open fire is impractical — which is most of urban Japan — a bon-chōchin does the work, hung at the entrance or beside the household altar for the duration.
Some regions end Obon with tōrō nagashi, floating paper lanterns released onto a river or the sea to carry the spirits back out. Anyone who has watched several thousand of them move downstream in the dark understands why this object never became merely ornamental in Japan.
A family buying its first bon-chōchin after a death is not shopping for a lamp. It is acquiring a fixture that will be brought out every August for decades — the same relationship Japanese households have with a great many seasonal objects, from the furin wind chime in summer to the decorations that come out only once a year.
Gifu, Noguchi, and the Lamp in Your Living Room
Gifu, in central Japan, has made lanterns for centuries, using mulberry-bark paper and local bamboo. By the mid-twentieth century the industry was in bad shape: mass-produced imitations had flooded the market before the war, and the war finished the job.
In the spring of 1951, the sculptor Isamu Noguchi passed through Gifu on his way to Hiroshima and watched the cormorant fishing on the Nagara River at night, each boat lit by chōchin. The mayor, learning that Noguchi was in town, asked him whether he could do something for the failing lantern trade. Noguchi had two designs sketched the following day.
He called the result Akari — a word meaning light in the sense of illumination, and carrying an implication of weightlessness. He replaced the candle with an electric bulb, and he replaced the accordion silhouette with rounded organic volumes drawn from his own sculpture. He entered into a partnership with the Ozeki family workshop, and Akari have been made there, by hand, ever since.
The detail that matters is what he refused to change. Noguchi insisted on keeping the collapsible frame — the property the Gifu makers regarded as unremarkable because it had always been there — precisely because it meant a sculpture could ship flat in an envelope and expand in a room on the other side of the world. He did not modernise the craft. He commissioned new shapes from it, and the technique is essentially the pre-industrial one.
The line runs directly from a fishing boat on the Nagara to a paper globe in a Copenhagen apartment. Few objects have made that journey without losing anything on the way.
Paper, Vinyl, and What Changed
Walk a Japanese street tonight and most of the lanterns you pass are not paper. They are vinyl, printed by machine, lit by a low-energy bulb or an LED strip, and they will survive rain that would destroy a washi lantern in an afternoon.
This is not a decline story, or not only one. A bar owner needs a sign that lasts through a typhoon season and costs what a sign should cost. Vinyl does that. What it does not do is age: a washi lantern yellows, softens, and eventually tears at the folds, and a shop that has hung the same paper lantern for thirty years is displaying its own longevity along with its name.
Hand-made chōchin survive where the object still has a job that vinyl cannot do — temples, shrines, festivals, funerals, and the workshops supplying them. Roughly the same division has settled over most Japanese crafts, from kokeshi dolls to paper screens, and it is a more stable arrangement than it sounds.
For anyone bringing one home, the practical guidance is short. Paper lanterns do not go outdoors in a wet climate. They discolour in direct sun. They are stored flat, not on a shelf where something can lean against them. Our Japanese lantern and decoration ranges sit at the domestic end of the same tradition.
Frequently Asked Questions
What is a chōchin?
A Japanese paper lantern built on a spiral of split bamboo covered in washi paper made from mulberry bark. Its defining feature is that it collapses flat between two wooden rings. The name combines the characters for carry and light.
What is the difference between a chōchin and an andon?
A chōchin is collapsible and portable. An andon is a fixed lamp with a rigid wooden or metal frame and paper panels, meant to stand on a floor or a table indoors. One is equipment for moving through the dark; the other is furniture.
What do the characters on Japanese lanterns mean?
Almost always a name. The shop or bar the lantern hangs outside, the dish it serves, the neighbourhood association at a festival, or the donor who paid for it at a shrine. The lettering is brushed by hand in a heavy style built for legibility from below and at speed.
What does a red paper lantern outside a bar mean?
It identifies an akachōchin — an informal, inexpensive drinking place serving grilled skewers and small dishes, without reservations or ceremony. In Japan the red lantern functions as the category name for that type of establishment.
How big is the lantern at Kaminarimon?
Roughly 3.9 metres tall, 3.3 metres wide, and about 700 kilograms. It is replaced approximately every ten years, and the metal base carries a plate commemorating the donation by Kōnosuke Matsushita, founder of Panasonic, that rebuilt the gate in 1960.
Is the Kaminarimon lantern really folded up?
Yes. During the Sanja Matsuri and other festivals it is collapsed upward so that portable shrines and tall floats can pass through the gate. The mechanism is the same spiral bamboo frame used in a lantern you could hold in one hand.
What is a bon-chōchin used for?
For Obon, the mid-August observance when the dead are held to return home. The lantern is hung at the entrance or by the household altar to guide the spirits and to see them off, replacing the welcoming and sending fires where an open flame is not practical.
What is tōrō nagashi?
The practice of floating paper lanterns on a river or the sea at the close of Obon, carrying the spirits of the dead back out. It is performed in many regions and is one of the largest lantern events in the Japanese calendar.
What are Gifu lanterns?
Chōchin made in Gifu, a centre of lantern production for centuries, using mulberry-bark washi and local bamboo. Gifu makers are known for fine paper and painted decoration, and the workshops there still produce lanterns by the traditional method.
Are Noguchi Akari lamps real chōchin?
They are made by chōchin methods, in Gifu, by the Ozeki workshop Isamu Noguchi partnered with in 1951, and they retain the collapsible bamboo frame. What Noguchi changed was the shape and the light source. The construction technique is essentially the traditional one.
What is a chōchin made of?
Split bamboo wound in a continuous spiral, washi paper from the inner bark of the mulberry, and two wooden rings at top and bottom. The frame is formed over a sectional wooden mould that is dismantled and removed once the paper has dried.
Can paper lanterns be used outdoors?
Traditional washi lanterns are not built for weather; rain destroys them and direct sun fades the paper. Modern outdoor lanterns are usually vinyl, which is why most street-level lanterns in Japan today are not paper at all.
How do you store a paper lantern?
Flat and collapsed, which is what the frame was designed for. Compressing it between the two rings and laying it down protects the folds. Storing it expanded on a shelf invites the crushing that eventually tears the paper along the bamboo lines.
A Sphere That Remembers How to Be a Disc
Seven hundred kilograms of paper and bamboo hanging over the busiest gate in Tokyo, and the answer to a festival float that will not fit underneath is to fold it up like a road map.
Everything else about the chōchin follows from that. A lantern that folds is a lantern you can carry, hang, store, ship in an envelope, and hand to a sculptor in 1951 who will send it round the world without changing how it is built.
