Inro
An inro is a small case made of a stack of tiny nested boxes, carried hanging from the sash of a kimono. It was created in the Sengoku period, from 1467 to 1615, as a portable case for a personal seal and medicine, became a fashionable men's accessory in the middle of the Edo period, and by the Meiji period had become an art object collected for its own sake.
Definition
The word joins in, a seal, with ro, a basket. An inro is one of the sagemono, the hanging containers of Japanese dress, but where others were made for one purpose, such as tobacco or a brush and ink, the inro was suited to any small thing and was most often used for medicine. Its boxes fit one on another, held together by two suspension cords. A sliding bead, the ojime, is pushed down the cords to keep the stack closed and slid up to open it; above the sash, a netsuke stops the cords from slipping.
Inro were made mostly of paper, wood, metal or ivory, and paper, layers of washi hardened with lacquer, was the most common, because, unlike wood, it would not warp or crack. Almost all are lacquered, and the finest are decorated in maki-e, sprinkled gold and silver, with shell inlay called raden, ivory inlay and metal foil.
Origin
Wealthy merchants of the townsman class and samurai collected inro through the Edo period, from 1603, and the inro became one of the most decorative kinds of Japanese lacquerware. As technique developed from the late Edo period into the Meiji period, from 1868, the inro stopped being worn and began to be collected as art. The finest pieces of the late Edo and Meiji periods were made to be looked at in the hand rather than worn, and they are read today as lacquer art first and accessories second. A plain, working inro in black lacquer belongs to the same family; it simply answers the first purpose, carrying medicine, rather than the second, display.

How to identify it
- Count the cases. Inro are described by their number of compartments; a five-case inro has five stacked boxes. Check that each opens and that the stack closes cleanly.
- Read the lacquer. Raised gold in relief is taka maki-e; flat gold is hira maki-e; gold polished level with the ground is togidashi.
- The inside. In our handling, the interiors of good inro are finished too, often in fine gold-flecked lacquer, and the rims fit without gaps.
- The cords. In our handling, original silk cords rarely survive; replacement cords are normal and should be described rather than hidden.
- Signatures. Many inro carry a lacquerer's signature at the base; read it with care, because names were used across generations of a workshop.
Where it appears in the collection
Inro sit beside netsuke on the netsuke, sagemono and inro shelf. We hold an Edo five-case inro in gold maki-e with flying cranes and pines, an Edo inro with chrysanthemums in maki-e and a Wajima lacquer turtle inro by Okuno Bihou. The family is read in full in our study of netsuke, inro and sagemono and in our guide to Japanese lacquer and maki-e.
