Kept in the Box: How Japan Cares for Jewellery and Watches

The box is orange, the colour Hermès adopted in 1942 when wartime Paris could offer it nothing else. On one edge a printed label still reads "Pointu 100% soie vintage Bolduc", followed by the colourway and a bar code. Inside lies a silk triangle printed with ribbons. The scarf is beautiful, but the label is what a collector reads first, because it means that someone, somewhere in Japan, kept the box, the label and the silk together for years. Pieces that pass through Japanese hands arrive this way often enough that we now expect it. This article sets out why: a centuries-old practice of boxing and inscribing treasured things, a gift culture in which the wrapping is part of the gift, a climate that punishes neglect, and a way of grading condition that rewards the owner who kept everything.

Read it alongside the flagship essay Why the World's Treasures Came to Rest in Japan, and our guides to Okachimachi, Tokyo's jewellery quarter, Ginza and the watch and gold in Japan.

Boxes that carry a history

Long before luxury houses printed their names on cardboard, Japanese owners of tea bowls, caddies and scrolls kept them in made-to-measure wooden boxes called tomobako. The Rhode Island School of Design Museum describes these boxes, made of wood or lacquer, as safeguarding tea utensils while documenting their history; a box may carry the potter's signature and the appraisals of tea practitioners. The Toledo Museum of Art holds one such authenticating box, made for a tea bowl by the potter Kawai Kanjirō (1890–1966), its lid inscribed by Kawai Takeichi to attest that Kanjirō made the bowl.

The writing itself has a name, hakogaki: inscriptions on the front and back of a lid that record where an object came from and how it was handed down. This autumn the Tokugawa Art Museum in Nagoya has given boxes an exhibition of their own, "Tokimeku Hako", which runs from 8 October to 15 November 2026. Among its loans is a Chinese tea caddy once owned by Katagiri Sekishū, founder of the Sekishū school of tea, kept in an inner pouch box of paulownia and a second box of cedar whose lids bear Katagiri's own handwriting. A celebrated incense burner is shown with its many boxes, one inside another, each added by a later owner.

The lesson for a collector of watches and jewellery is direct. In this tradition the box is not packaging to be thrown away. It is the object's record: who made it, who owned it, who vouched for it. A watch that returns with its box, guarantee card and the receipt folded inside belongs to the same habit of mind, even when the box is leather and the inscription is a printed serial number.

Wrapped with intent

The second habit is wrapping. The furoshiki, the square cloth used to carry and present things, descends from tsutsumi, wrapping cloths that temples used in the Nara period (710–794) to protect sacred texts and ceremonial objects. Its name joins furo, bath, and shiki, to spread: in the Muromachi period the shogun Ashikaga Yoshimitsu built a great bathhouse in Kyoto, and guests marked their cloths with family crests so they could find their belongings. In the Edo period townspeople carried tools, gifts and lunch boxes in them.

Wrapping also carries meaning in the gift calendar. Nippon.com's guide to etiquette explains that the midsummer and year-end gifts, ochūgen and oseibo, grew from offerings to ancestors; in the Edo period merchants gave gifts to their best customers at the half-yearly settling of accounts, and department stores later turned both seasons into gift campaigns. Such gifts travel in boxes wrapped in noshigami paper with mizuhiki cords, which stand for a prayer for the recipient's happiness, and the guide notes that boxes are wrapped impeccably. In a culture where the presentation is part of the courtesy, the box that held a watch or a bracelet is naturally kept.

Behind both habits sits a word. In February 2005 the Kenyan environmentalist Wangari Maathai, the 2004 Nobel Peace laureate, told Prime Minister Koizumi Junichirō that she had been struck by mottainai, roughly the sense that valuable things should not be wasted, and that she wanted to carry the idea around the world. The following year Environment Minister Koike Yuriko promoted a "Mottainai Furoshiki" as an answer to plastic bags.

Six weeks of rain

Care in Japan is also a matter of climate. Every early summer the rainy season, tsuyu, settles over Kanto; in 2024 the Japan Meteorological Agency declared it begun on 21 June, fourteen days later than in an average year. Coto Academy, writing for residents of Tokyo, describes the season as a summer-long contest between warmth, humidity, poor ventilation and mould.

The household answer is unglamorous and thorough. Supermarkets sell electricity-free dehumidifying tubs (Mizu Tori Zō-san is a familiar brand) that collect water from closets and shelves and are replaced after about a month. The small desiccant sachets that come with new shoes and dried foods are kept and tucked into wardrobes, refreshed every one or two months. Sunny days are for opening windows. A leather bag that lives in such a closet, in its dust bag, has every chance of leaving it as it went in.

Silver, leather and steel: what harms each

Three authorities set out the risks clearly. The Canadian Conservation Institute explains that silver tarnishes when it reacts with sulphur gases, above all hydrogen sulphide; wool felt and vulcanised rubber, rubber bands included, give those gases off, sterling tarnishes faster than pure silver because of its copper, and every material tarnishes faster as humidity climbs, so silver is best kept below 50 per cent relative humidity. Blackened silver is the exception to polishing: the dark recesses of a Chrome Hearts piece are part of the design, as Chrome Hearts: Hollywood Silver and the Tokyo Stores explains. Louis Vuitton advises keeping a bag in a breathable dust bag, lightly filled so it holds its shape without being stretched, away from direct sunlight, damp and heat. Grand Seiko's handling cautions ask owners to keep a watch away from strong magnetism, high humidity, temperatures below 5°C or above 35°C for long periods, and the vapour of polish remover or thinners, and to lay a soft cloth between the case back, band and clasp when the watch is set down.

Material	What harms it	The Tokyo habit	What we suggest at home
Sterling silver	Sulphur gases from wool felt and rubber; damp air	Original pouch or box, closet kept dry through the rainy season	A dry drawer below 50% humidity; no rubber bands or wool felt nearby; polish rarely
Leather bags	Damp, heat, direct sun, crushing	Dust bag, box, dehumidifier tub in the wardrobe	Breathable dust bag, lightly filled; a cool, ventilated shelf, never plastic
Mechanical watches	Magnetism, humidity, heat and cold, solvent vapour, knocks	Kept in its own box with the guarantee and booklet	Away from speakers and phones; a soft cloth under the case back; service on the maker's schedule
Silk scarves	Light, moisture, sharp folds	Flat in the original box with its label	Flat or loosely rolled, out of the light, in the box it came with

What the houses put in the box

The brands we carry each leave their own trail of evidence, and a careful owner keeps all of it.

• Hermès. The orange box is itself a piece of history. Before the war the house used cream and gold boxes and marigold ones edged in bronze; in 1942, with packaging rationed in Paris, the only stock the house could obtain was orange, and the colour stayed. Our Hermès collection lists which pieces keep their boxes, dust bags, locks and clochettes, and our guide to Rodeo charms and the Chaîne d'Ancre shows how much the small boxed pieces are prized complete.
• Chanel. For decades a Chanel bag carried a hologram serial sticker inside and an authenticity card bearing the same number. From 2021 a slim metal plate with an embedded chip replaced both on most classics, so a bag from that year may have either. A card that matches its sticker is one of the reasons a collector of the Chanel collection asks whether the papers were kept; jewellery is covered in our field guide to Chanel earrings and brooches.
• Louis Vuitton. Date codes, letters for the workshop and digits for the week and year, are stamped inside most pieces made before 2021; from March 2021 many bags and accessories carry an embedded microchip instead. Our guide to vintage Louis Vuitton canvas bags explains how to read them, and the Louis Vuitton collection notes each piece's code.
• Watches. A box, the guarantee card, the booklet, spare links and the original receipt make a full set. Our essay What Makes a Full Set? explains why each part matters, and the collectible watches record each piece's inclusions.

The grade on the label

This care shows up in a vocabulary. Japanese condition grades, used across the country's trade in pre-owned luxury, run from N for new through S (unused), SA (near unused), A (very good), AB (light signs of use) and B (visible signs of use) to C (marked wear). Because the scale is shared, a piece kept in its box through every rainy season reaches a higher grade and is described more exactly than one that was not. Our guide Japanese condition ranks, explained sets out what each letter allows.

Craft and the honest mend

Respect for an object begins with respect for its maker, the idea at the centre of our essay on monozukuri, shokunin and the mingei ideal. Its opposite pole is not neglect but repair. Kintsugi mends a broken bowl with lacquer and gold so that the break becomes part of its story. One habit keeps the box so nothing is lost; the other keeps the scar so nothing is hidden. Both refuse to treat a fine thing as disposable.

Where the record differs

Completeness can be overstated. Box and papers raise value, which gives forgers a reason to make them: the dealer Bezel cancelled the sale of a genuine 1990s Rolex Day-Date because its papers were counterfeit, printed with a reference, 182388, that Rolex never used. A full set is evidence to be examined piece by piece, not proof in itself.

Five things worth knowing

1. Hermès orange was a wartime necessity: in 1942 it was the only packaging colour left to the house in rationed Paris.
2. Japanese has an idiom built on the box: hakoiri musume, "a daughter in a box", means a sheltered young woman.
3. When the Mottainai Furoshiki went on sale in 2006, a Printemps Ginza fair sold 800 in two weeks; the store had previously sold about ten a month.
4. In the Tokugawa Art Museum's current exhibition, a sword is shown with a bag, a box and a separate box for its mountings: three layers for one blade.
5. The Kawai Kanjirō box in Toledo is dated about 1970, after the potter's death in 1966: the authentication was written later, by Kawai Takeichi.

Frequently asked questions

Does a missing box lower a piece's value?

For watches and for the most collected handbags, usually yes, because a complete set is easier to verify and to pass on. For older jewellery and silver the piece itself matters most; we always state exactly what is included.

How should I store a silver piece from Japan at home?

Dry, below about 50 per cent humidity, away from wool felt and rubber, which give off the gases that cause tarnish. A closed drawer with its original pouch serves well.

Should I keep a leather bag in plastic?

No. Louis Vuitton recommends a breathable dust bag, lightly filled, in a cool, dry and ventilated place out of direct sun.

Are Chanel authenticity cards still issued?

Not on most classic bags made from 2021, when a metal plate with a chip replaced the hologram sticker and card. Bags from the changeover year may carry either.
