The tradition · written by opus-5.5,
In Japan hemp is a sacred fibre. It stands for purity, and since ancient times it has been used to cleanse, to mark holy ground and to carry prayers. Japan has also kept and tightened its cannabis law while other industrial countries relaxed theirs. The two facts have stood side by side since 1948: the religion uses the fibre, and the law is aimed at the flower and leaf.
An ordinary crop
Hemp is among the oldest cultivated plants in Japan, grown since the Jōmon period at least six thousand years ago, for food and for fibre: clothing, rope, nets, later paper. Hemp artefacts have been dug from the Torihama shell mound. By 645 the Yamato court taxed it. It was the cloth of ordinary people, while the rich wore silk, until cotton displaced it in the Meiji period. The Japanese word is taima, from Chinese.
It also had lighter uses. Bundles of hemp were burned at the Bon festival to welcome the spirits of the dead, and an American historian of the early twentieth century noted travellers leaving cannabis leaves as offerings at roadside shrines for a safe journey. How far it was ever used as an intoxicant is unclear; any ritual use of that kind is thought to have been suppressed with the arrival of Confucianism.
What Shinto does with it
| Object | What it is | The part hemp plays |
|---|---|---|
| Ōnusa | The wand a priest waves, left, right and left, over a person or thing to be purified | Hung with paper streamers or with strands of hemp fibre. The impurity is believed to pass into the wand |
| Shimenawa | The twisted rope that marks a sacred place or object | Hemp was its basic material from ancient times |
| Jingū taima | The talisman issued by the Ise shrine and kept on the household altar | It began as a purification wand given out by the shrine’s travelling preachers. The name is written with the characters for hemp |
In Shinto hemp is regarded as a sacred substance with a meaning of purity and fertility.
The Ise talisman shows how deep the custom went. A document of 1777 indicates that between 89 and 90 per cent of all households in the country owned one.
1948
Under the American occupation Japan passed the Cannabis Control Act of July 1948. It banned possession and put cultivation under licence. It did not punish use, which is usually explained as protection for farmers who breathed in their own crop. In the months before, Emperor Hirohito is said to have given assurances that farms growing hemp for industry would be allowed to go on.
They went on for a while. In 1950 Japan still had about 25,000 hemp farms. Then synthetic fibre and the cost of licences did what the law had not, and the number fell year after year.
The effect on religion was practical. After 1948 shimenawa began to be made of rice straw instead.
Now
By 2016 there were 37 licensed hemp farms, most of them in Tochigi prefecture, which grows about nine-tenths of the country’s hemp. They are required to plant Tochigishiro, a variety with almost no THC, bred after the war and issued to farmers as seed by the government. Most hemp used in Japan is imported.
The law has moved the other way. In 2024 Japan made use itself a crime for the first time and raised the maximum sentence for possession to seven years, while allowing medicines derived from the plant.[1][2][3][4]
