Traditionally Used Raw Materials
History and Characteristics

In that ivory possesses a smooth texture, beautiful luster, the subtleness of vein patterning and ideal hardness; it offers everything that is required of a superior material for traditional crafts. As such, since ancient times it has been highly-prized in both Eastern and Western cultures.

In Ancient Egypt, ivory created opulent furniture and personal ornaments; in Ancient Greece and Rome, it was the material from which countless deity statues were fashioned. Ivory also has a rich usage tradition in China. With large volumes imported by China from India and Thailand during the thriving commerce of the Sui and Tang Dynasties, ivory was a material that came to be loved by the ruling classes, it being employed by the Chinese to create decorative furniture among other forms.

Based on ivory pieces held by the Shoso-in (the treasure house of the Todai-ji Temple in Nara Prefecture), it can be understood that Chinese carving techniques were conveyed to Japan during the Nara Period (710-794). Within the Shoso-in collection, there is a rule (a scepter) used in religious ceremonies that features intricate ivory carvings. There are also Biwa (Japanese lute) plectrums, and stones for the board game of go, etc., all of which have been fashioned from ivory.

Furthermore, in that the Shoso-in also possesses samples of unprocessed ivory (in its natural state), it is possible to appreciate that processing and the creation of ivory pieces was also conducted in Japan in ancient times.

To explain what ivory is, it represents the grown tusks of elephants, with large examples being three to four meters in length, and sometimes weighing between 40 to 60 kilograms. The tusks of female elephants tend to be narrow and long, while the tusks of males are both strong and thick.

It is said that ivory product manufacture in Japan commenced with spoons and other accoutrements (such as container covers used in the tea ceremony). During the middle of the Edo Period (1603-1868), ivory pieces came to be widely used, with items such as netsuke, hair ornaments and samisen plectrums, etc., coming into use. This resulted in ivory being loved by people of many different classes from the samurai to the townsfolk of Edo.
