Japanese culture has a tradition of cannabis use dating back at least 10,000 years, with scientific certainty of its cultivation on all its islands for more than 2,000 years. On the northern island of Hokkaido hemp has been grown traditionally since time immemorial. In fact, cannabis grows wild in Hokkaido, with authorities having to eradicate nearly a million plants every year.
This landrace cannabis strain from Hokkaido has broad leaves and fat stems, growth characteristics usually associated with Indica varieties. The general appearance and leaf morphology of this Japanese variety bring to mind the Indica phenotype of China Yunnan, although the Hokkaido has darker leaves, greater vigour, longer node spacing and more branching.
Hokkaido Japan regular seeds shows semi-autoflowering characteristics, meaning that outdoors it starts flowering quickly after summer solstice. It has a spiky floral development similar to a Sativa but flowers develops very quickly and maturing in only 6-8 weeks.
Three main phenotypes have been identified in this strain:
Group A: High CBD content (10 %), moderate THC content (5,5 %), high CBG content (3%) and a 2:1 CBD:THC ratio. Increased terpene content with much stronger and appealing aromas than the others.
Group B: High CBD content (9-12 %), very low THC content (0,4-0,5 %), low CBG content (0,6-0,8 %) and a 22-25:1 CBD:THC ratio.
Group C: Low-moderate CBD content (2 %), extremely low THC content (0,1%), extremely low CBG content (0,05-0,1 %) and a 22-25:1 CBD:THC ratio.
Genetic analyses indicate that Hokkaido Japan is a uniform variety, homozygous and with very little genetic variation. This is a rare and unique genotype, not related to other varieties of European or Russian hemp. Its origins suggest that it's related to Chinese or Korean cannabis varieties. Its lack of, or very low hermaphroditism is a sign of traditional breeding at some time in its development.
Hokkaido Japan regular seeds is a very interesting pure, stable and fast-ripening landrace for the development of new hemp strains (with high or low CBD content). It grows well indoor, and outdoors up to 50ºN in hot climates and in zones where flowering coincides with rain and low temperatures. Moderate levels of nutrients for the whole cycle are recommended. Allow plants to reflower if searching for higher cannabinoid count. Most plants during phenotype trials were harvested in week 10-11 of flower.
The HIHA (Hokkaido Industrial Hemp Association) has recently signed an agreement with the French government to introduce new European hemp varieties with very low THC content (less than 0.2%) in Hokkaido, meaning that the old traditional varieties on the island could be replaced and become extinct in the short term.
