12,000-YEAR THREADS
Cannabis in Japan traces back to the Jōmon period (10,000–300 BCE), where archaeologists uncovered hemp rope and seeds more than 12,000 years old. Sites such as Torihama and Tsunan revealed pollen and fibers that confirm early cultivation. Even the word “Jōmon” means “cord-pattern,” most likely tied to hemp rope impressions used in pottery.
IMPORTED OR INDIGENOUS?
Scholars generally agree that cannabis reached Japan from China and Korea around 300 BCE. A cave painting in Kyushu depicts hemp-like plants with wave motifs and traders, hinting at its introduction through maritime exchange. This aligns with broader patterns of agricultural and cultural imports during that era.
JŌMON TO YAYOI
Between 300 BCE and 300 CE, hemp cultivation spread widely. The Ainu people wove ceremonial hemp garments, while Yayoi farmers relied on hemp for fishing nets, textiles, and agricultural tools. With farming and metallurgy advancing, hemp emerged as a staple crop alongside rice.
SHINTO’S SACRED HERB
Cannabis assumed a central role in Shinto spirituality. Priests used hemp gohei wands during purification rites, and hemp (taima) was burned at the Ise Grand Shrine. Sacred hemp ropes, or shimenawa, still adorn shrines and remain integral to imperial rituals, symbolizing purity and divine connection.
ZEN, MEDICINE, AND HEMP
Historical accounts also note medicinal applications, where cannabis was brewed into teas and tinctures. Zen monks prized its clarity-enhancing qualities, although records are scarce regarding recreational use. The cultural context suggests cannabis was viewed with reverence for both healing and spiritual clarity.
SYMBOL OF STRENGTH
Cannabis symbolized resilience and vitality in Japanese culture. Children were sometimes named after hemp to embody strength and durability. For farmers, warriors, and priests alike, it stood as an indispensable resource, paired with rice as a foundation of survival and ritual.
THE AMERICAN INTERRUPTION
Following World War II, U.S. occupation authorities imposed strict controls on cannabis. In 1948, the Cannabis Control Act criminalized its cultivation and use, erasing centuries of cultural integration. Farmers resisted, but their protests were silenced under occupation policy.
DECLINE AND RESTRICTION
In 1954, more than 37,000 licensed hemp farmers remained active. Today, fewer than 30 survive, strictly permitted to cultivate hemp for fiber or research. Most modern Japanese citizens are unaware that “taima,” once a sacred and essential plant, is now a controlled substance.
LEGACY LOST, NOT FORGOTTEN
From prehistoric ropes to Shinto shrines, cannabis is deeply interwoven into Japan’s cultural fabric. Though outlawed, its legacy endures in language, ritual, and memory. As global attitudes evolve, Japan may eventually reconsider and reclaim this ancient green thread.
