Tochigishiro ( Japanese: とちぎしろ) is a cultivar of hemp grown in Tochigi Prefecture, Japan. It meets international standards of non-narcotic agricultural hemp at about 0.2% THC, [2] [3] reckoned "remarkably low" by Sensi Seeds. [4] It was grown in the early 20th century at Arlington Experimental Farm near the United States capital. [5] The modern variety was developed beginning in 1973 by Kyushu University professor of pharmacy Itsuo Nishioka from seeds "found in southern Japan", [6] and completed c. 1982 by the Tochigi prefectural government at Tochigi Agricultural Experiment Station in Tochigi-shi. [7] [8] According to a National Institute of Mental Health-affiliated researcher, the strain is missing the enzyme tetrahydrocannabinolic acid synthase that makes most Cannabis capable of producing THC. [9] It is the most widely grown cultivar in Japan in the 21st century, being exempt from prohibition under the Cannabis Control Law, due to its low levels of psychoactive chemicals. [10] [11] Approximately 90% of the hemp grown in Japan is the Tochigishiro variety (as of 2007). [12]
A research report on an experimental plot at Kitami Agricultural Experimental Station on Hokkaido suggests that it may be the most productive known crop for biomass, yielding 52.7 tonnes/ha in a single season. [13] The crop grows about 3 metres (9.8 ft) tall. [8]
