アイヌと刀剣——イコロとしての宝刀
Ainu and the Sword — Sacred Blades as Ikoro
For the Ainu people, Japanese swords carried a distinctive cultural meaning as trade goods, prestige objects, and spiritual treasures (ikoro). Swords that entered Ainu society through trade with the Matsumae domain were integrated into a meaning-system unlike that of the Japanese, forming a unique indigenous sword culture.

The Ainu Concept of Ikoro
In the Ainu language, ikoro means 'treasure' or 'wealth,' specifically prestige objects believed to hold spiritual power. The highest-ranking ikoro was the Japanese sword (emushi in Ainu), linked to the authority of the community leader (kotan-koro-kuru). For the Ainu, a sword was not merely a weapon but a sacred presence inhabited by ancestral spirits, passed down as a family and clan heirloom.
Influx of Japanese Swords through Trade
In trade with the Matsumae domain (the Edo-period ruler of Ezo), the Ainu offered salmon, kelp, furs, and hawks in exchange for rice, sake, cotton, iron goods, and swords. Swords ranked among the most valued Japanese trade goods and played an important role as gifts at ceremonial feasts (umesa), marriages, and alliance-sealing. Most incoming blades were practical Edo-period uchigatana and wakizashi, though some earlier kotō were included.
Ainu Patterns of Sword Use
Ainu men routinely carried an emushi (belt knife), but their uses differed from Japanese practice. Primary uses were daily tasks: butchering bear and deer, woodworking and craft. Ritual contexts included cutting offerings to deities and participation in iyomante (the bear-sending ceremony). The sword also carried protective spiritual significance, playing roles in rites of passage such as birth and funerals.
