Mammoth Tusk Netsuke: The Material, the Carving and the Rules

Our thesis: a mammoth tusk netsuke is a modern object in an Edo form, and it should be read honestly as both. The form, the toggle that held a hanging box to a sash, is three centuries old; the material is ancient; the carving is usually recent. Read the material, then the form, then the hand, and describe each truthfully. The wider family of hanging objects is set out in our guide to netsuke, inro and maki-e, and the alternatives to elephant ivory in our careful guide to ivory and its substitutes.

At a glance

An ivory from the ground

Mammoths are told from living elephants by their large, spirally twisted tusks. The woolly mammoth evolved in Siberia, and the last mainland populations survived until about 10,000 years ago; an isolated group on Wrangel Island in the Arctic Ocean lasted until about 4,000 years ago, when the first civilisations of Egypt and Mesopotamia already stood. Some estimates suggest ten million mammoths or more still lie buried in Siberia, which is why their tusks continue to surface.

People have worked this ivory for as long as they have known the animal. Upper Palaeolithic hunters carved it into figures and engraved it with mammoths; a piece found in 1864 in the Dordogne bears the first known contemporary picture of a prehistoric animal. The Mongol khan Güyük is said to have sat on a throne of it in the thirteenth century. Siberian ivory is reported to have reached Russia and Europe in the tenth century, and the trade grew after Russia occupied Siberia. From the nineteenth century the material was highly prized, and today it is still in demand as a replacement for elephant ivory, whose export is banned.

Why it became a netsuke material

Japanese clothing had no pockets. Men carried pipes, tobacco, money and seals in hanging containers called sagemono, most famously the lacquered box called inro, held shut by a sliding bead, the ojime, and hung from the sash by a cord ending in a toggle, the netsuke. Netsuke appeared in the seventeenth century, were most popular through the Edo period, and declined as dress was westernised from the Meiji period onward. Edo carvers used boxwood and other hardwoods, ivory, horn and many other materials.

The craft did not stop. Netsuke are still made today, and some modern pieces command serious attention in Japan, Europe and the United States. Mammoth tusk now supplies part of that work, because huge quantities of it still exist. In our handling, the best modern pieces use the tusk's density for crisp, deep relief, and its grain for movement in robes and fur.

Reading the form

A netsuke is first a working object, so the form comes before the subject. The most common type is katabori, a small sculpture in the round. Manju is a thick, flat, round form, carved in relief; ryusa is a manju carved through like lace, so that light passes through it; men netsuke are masks after the Noh theatre; kagamibuta has a metal lid set into a shallow ivory bowl. Every true netsuke has a way for the cord to pass, either two holes, the himotoshi, or an opening in the design itself.

Our shelves show the range. A ryusa-style manju of cherry blossom with pink-stained petals shows the openwork form; a manju of Raijin, the thunder god, among townsfolk shows deep relief; a cluster of Noh and Kyogen masks gathers the mask form into one piece; and a crouching white rabbit with red inlaid eyes is katabori at its simplest. The terms are gathered in our glossary of netsuke terms.

Telling mammoth from elephant

The decisive evidence is in the cross-section. Polished ivory from a tusk shows a checkerboard of crossing lines, the Schreger lines, and where they meet they form angles. In extinct proboscideans such as the mammoth, the outer Schreger angles are acute; in living elephants they are obtuse. Where a flat or cut face shows the pattern, as on the base of some carvings, the angle is the best visual guide there is.

On a finished netsuke that face is often hidden, and then the reading becomes careful rather than certain. In our handling, mammoth tusk often carries mineral-toned patches, from cream to brown or blue-grey, from its long burial, and carvers frequently leave them as colour. Imitations exist too: ivorine and other ivory substitutes have none of the striations of animal ivory, though they are sometimes artificially aged. We name the material in every title as mammoth tusk, and where a piece is stained, engraved or inlaid we say so, as on a Kannon within a lotus petal with engraved red-brown robes or the left-hand shishi of a pair inlaid with coloured stones.

The rules, and what to check before shipping

Rules on ivory differ by country and change over time, so we keep this part narrow. The United Kingdom's guidance on the Ivory Act 2018, published by Defra and the Animal and Plant Health Agency and last updated on 24 July 2026, requires an exemption to deal in items made of or containing ivory from the species it lists: elephant, hippopotamus, killer whale, narwhal and sperm whale. Mammoth is not on that list in the version we read. The same guidance reminds readers to check other rules that may apply, including permits to import or export endangered species, and it sets maximum penalties of a £250,000 fine or five years' imprisonment for dealing in listed ivory without an exemption.

Outside the United Kingdom we make no general statement. Buyers must check their own country's import rules, and any rules where they live, before ordering a piece made of mammoth tusk; we describe the material plainly so that they can.

Where the record differs

The record holds two views of the modern netsuke at once. One describes mammoth pieces as filling part of today's tourist demand for netsuke; another notes that modern netsuke can command high prices in Britain, Europe, the United States and Japan. Both are true, because the material says nothing about the hand. A mammoth tusk netsuke can be a souvenir or a work of art, and only the carving decides which.

In the archive

The house keeps its netsuke on the netsuke, sagemono and inro shelf, with an open room for browsing on the netsuke open room shelf. Beside the pieces above sit a pair of men at kubi-hiki, the neck tug-of-war, a gourd-form netsuke inlaid with the flowers of the four seasons and an ojime bead carved as a coiled snake, the bead that once closed an inro. The humorous and erotic subjects of the tradition are read in our guide to erotic and humorous netsuke.

Answered plainly

Is mammoth tusk the same as elephant ivory?

No. It is the tusk of the extinct woolly mammoth. The two can look alike; the outer Schreger angles on a cross-section are acute in mammoth and obtuse in living elephants.

Are mammoth tusk netsuke antiques?

Usually not. The material is ancient, but most mammoth tusk netsuke are modern carvings, and we describe them as such.

Can I import a mammoth tusk netsuke into my country?

Rules differ by country. We cite only the UK guidance we have read; buyers must check their own country's import rules before ordering.

What is a himotoshi?

The pair of holes, or the opening in a design, through which a netsuke's cord passes. Its okimono cousin, purely decorative and usually larger, was made to be placed rather than worn.

The Edo carver chose his material from what was at hand; the modern carver chooses mammoth because the Siberian ground still gives it up. Read the angle if you can see it, read the form, then judge the hand, and the netsuke will tell you whether it is a souvenir or a small sculpture. That is our reading.
