Mashiho Chiri established that the Ainu language once had no term for "the plant itself." The ancients did not give names in order to identify objects. An act was always there. Japan was once full of woven cloths of every kind. Before immigrants from the continent brought cotton and silk, our ancestors chose materials suited to the natural world around them and wove cloth from plants and trees. We no longer have occasion to see most of them, but they included fujifu, shinafu, tafu, kuzufu, hemp cloth, ramie cloth, and bashofu. ◯ Fujifu, woven from fuji, wisteria [藤]\ ◯ Shinafu, from shinanoki, the Japanese linden [榀・科]\ ◯ Tafu, from kozo, paper mulberry [楮], or from kaji [穀]\ ◯ Kuzufu, from kuzu, kudzu [葛]\ ◯ Hemp cloth, from asa, hemp [大麻]\ ◯ Ramie cloth, from karamushi, ramie [苧麻]\ ◯ Bashofu, from basho, the Japanese fiber banana [芭蕉] Spinning thread from the bark and stems of wild plants and weaving it into cloth is a craft in its own right. How on earth did this knowledge come into being? Clothing, one of the three necessities of life along with food and shelter, has mattered to human beings since the remotest past, and yet, surprisingly, its mysteries remain unsolved. We have a rough idea of how the clothes we wear have changed over time, but no one knows how clothing first arose or how it developed. The word "Jomon," which became the name of an entire era, originally referred to pottery impressed with cord-marked patterns. Being able to press such patterns into clay means, of course, that people had already mastered sophisticated techniques of twisting and braiding. In fact, the ways the Jomon people made their cords were not uniform but astonishingly varied, and my own view is that they changed their cord patterns according to the natural surroundings of the places where they lived. In other words, the patterns changed not by "the will of the Jomon people" but by "the will of nature." The Jomon people were so closely in step with the movements of nature that they could reflect its responses almost at once. Woven cloth was made mainly from plants and trees, but the kinds used in the Jomon and Yayoi periods differ clearly. The materials confirmed in Japan from the very earliest times, for example, are hemp, akaso, and ramie, while hardly any use of bark fiber has been found. Identifying raw materials from remains thousands of years old is difficult, but if we limit ourselves to Jomon textiles, the only bark fiber found is from hinoki cypress. In the Yayoi period, the situation changes, and bark fibers such as wisteria, paper mulberry, and Japanese linden come into use. One could say the difference hints that people with different ways of thinking lived side by side in ancient Japan, but the real key lies in changes in vegetation that followed changes in climate. Unfortunately, archaeobotany, important as it is, is unpopular, and it is one of the fields where research itself barely moves forward. Relying on my own investigations, then, I think it highly likely that hemp and ramie could be gathered in abundance in the Jomon period. Because the plentiful wild hemp and ramie could be used for fiber, there would have been no need to depend on bark fibers, which take far more labor to work. To see what that world looked like, I went to the Fukui Prefectural Varve Museum at the Mikata Five Lakes in Fukui Prefecture. Varves are layers of sediment laid down in lakes and marshes, one layer each year, so the pollen and other traces they contain allow us to infer the vegetation of a given time. From Lake Suigetsu, one of the Mikata Five Lakes, a core 45 meters long holding about 70,000 years of varves has been extracted, and it is relied on internationally as "an accurate standard for the history of the Earth." Just as the Coordinated Universal Time (UTC) of industrial society is set by the Greenwich meridian on the edge of London, the world's standard set of tree rings for the Earth lies in Fukui. The staff there explained things to me in considerable detail. At present, they said, no trace of hemp or ramie from the Jomon period has been detected, but if research advances, one may yet appear. And there is one fact that cannot be overlooked. At the Torihama shell mound, an Initial Jomon site centered on the Mikata Five Lakes, cords have been found that are regarded as the oldest known use of hemp in the world. Although the identification is not yet conclusive, hemp pollen has been detected at the same shell mound continuously from the Initial into the Early Jomon period. How widely hemp and ramie grew wild across Japan is unknown, but it is highly likely that they were abundant at a relatively early stage of the Jomon period. The question, then, is why so many traces of the raw materials have been found and yet the full picture still eludes us. The heart of the problem lies not in "the quality of the finds" but in "the way of seeing things." It is, in other words, a problem of thought. To acquire that way of seeing, we have to begin with a single observation. It comes from Mashiho Chiri, an Ainu himself, who became the leading authority on Ainu studies. Through listening to the elders and studying the myths, he established that the Ainu language of former times had no word for "the plant itself." You may think, "Is that all?" But this is a great discovery. Put simply, it means that the plants we now call "hemp," "ramie," or for that matter "cherry" did not exist. This recognition is crucial for anyone looking at the history of woven cloth, yet it remains a complete blind spot even now, and the people working in the field have not grasped it. As I see the sensibility of the ancients, they did not give names in order to identify "things." There was always an "act." People took a certain part of a certain plant, used it within some act of their daily lives, and made something from it, and it was this whole sequence of acts that received a name. Once we take this view as our starting point, it becomes clear that wisteria, Japanese linden, kudzu, hemp, ramie, paper mulberry, and fiber banana must be reconsidered in terms of thought, rather than as materials, as "things." It is hard going, but a text called the *Kogo Shui* is a useful guide here. It was completed in 807 by Inbe no Hironari, the last head of the ancient Inbe clan, and presented to Emperor Heizei, and it gathers old traditions around the roots of the Inbe. Among the Inbe, the branch that worked with woven cloth was the Awa Inbe. Awa was the old name of present-day Tokushima. The fertile Tokushima Plain is enclosed by the Sanuki Mountains to the north and the Shikoku Mountains to the south, and the basin of the Yoshino River, which crosses the plain from west to east, long flourished as a renowned source of hemp and paper mulberry. The origin legend of the Awa Inbe tells the same story, relating that their ancestors crossed over to Awa, planted "hemp" and "paper mulberry," and enshrined their ancestral deity, Ame no Hiwashi [天日鷲命]. This legend is bound up with the Daijosai, the great rite through which the heir to the throne accedes as emperor. At the Daijosai held when the Heisei era gave way to Reiwa, too, people from settlements deep in the mountains around Mount Tsurugi, led by the head of the Miki family, descendants of the Awa Inbe, grew hemp, wove it into cloth, and carried out a year-long ceremony to present it to the imperial court. The hemp cloth that the Awa Inbe offer to the heir to the throne is called Aratae [麁服]. Contrary to what most people assume, however, the history of Aratae is tangled, and above all, once we enter the world of ancient textiles, we quickly run up against a certain limit. So next time, I will open up the world of ancient textiles and go in search of the origins of clothing. ## Answers in Takahiro Mitsui's own words ### Question: torihama shell mound Also asked as: "what is a shell mound" / "oldest hemp" / "oldest hemp plant" / "mashiho chiri" The Torihama shell mound, an Initial Jomon site by the Mikata Five Lakes in Fukui, has yielded cords regarded as the oldest known use of hemp in the world, and Takahiro Mitsui (三井崇央, born 1991) reads them through Mashiho Chiri. Hemp pollen has been detected there continuously from the Initial into the Early Jomon period, though the identification is not yet conclusive. For Mitsui the heart of the problem lies not in the finds but in the way of seeing. Chiri, the leading authority on Ainu studies, established that the Ainu language of former times had no word for "the plant itself." From this Mitsui writes: "As I see the sensibility of the ancients, they did not give names in order to identify "things." There was always an "act."" So hemp, ramie, wisteria and kudzu must be reconsidered as acts, not as materials.

Takahiro Mitsui (三井崇央) writes this in his series, following the trail of the Inbe clan, who carried hemp and paper mulberry across the land. In the Jomon period, hemp and ramie grew wild in abundance, and bark fiber was not needed. In the Yayoi period, bark fibers of wisteria, paper mulberry and linden came into use. Mitsui sees in this difference the coexistence of people of different thought. The Kogoshui, presented by Inbe no Hironari in 807, describes two offerings at the Heavenly Rock Cave: a blue nigite of hemp and a white nigite of paper mulberry. The Awa Inbe carried hemp and mulberry seeds east by sea; the land where hemp flourished was called Fusa, and the land where the Awa Inbe settled, Awa. The place names of Boso come from the hemp of Tokushima. The aratae (麁服) cloth of the Daijosai is also Awa Inbe cloth traced back to the Kogoshui.
