Hokkaido Japan Hemp is a rare and ancient landrace from Japan’s northernmost island, where cannabis has been cultivated for over 2,000 years.

This 50/50 indica-sativa hybrid exhibits a robust, stocky structure with thick stems and broad, dark leaves, resembling classic indicas, yet flowers with spiky, fast-maturing buds similar to sativas.

With high resistance to cold, mold, and rain, this strain thrives in temperate and high-latitude regions (up to 50°).

The semi-autoflowering nature ensures early flowering, making it a great choice for short-season growers.

While traditionally used for fiber and textile production, some phenotypes contain notable cannabinoid profiles, with select plants offering higher CBD, THC, and CBG content.

Genetics & Origins

Hokkaido Japan Hemp is a historically significant landrace, deeply rooted in Japan’s agricultural tradition.

Unlike European or Russian hemp varieties, this strain’s genetic profile suggests a closer relation to Chinese or Korean cannabis.

Though primarily cultivated for fiber, some plants still retain moderate cannabinoid production, offering unique breeding potential for CBD, THC, or CBG-rich selections.

Recent studies on this strain have identified three primary phenotypes based on their cannabinoid profiles:

  1. Balanced (THC:CBD:CBG) – High CBD (~10%), moderate THC (~5.5%), high CBG (~3%)
  2. CBD-Dominant – High CBD (9-12%), low THC (0.4-0.5%), low CBG (0.6-0.8%)
  3. Industrial Hemp – Low CBD (~2%), trace THC (0.1%), minimal CBG

Effects & Experience

  • Very mild psychoactivity, offering a subtle sense of relaxation and light euphoria.
  • Low THC phenotypes provide functional clarity, suitable for daytime focus and productivity.
  • Higher THC phenotypes may induce slight hilarity and an uplifting mood shift.

Flavor & Aroma

  • Natural, earthy, and wild, with hints of geranium and mountain herbs.
  • Most plants exhibit minimal terpene complexity, with only traces of alpha-pinene.
  • Select phenotypes (Group A) develop richer, more appealing aromas with elevated terpene content.

Growing Information

Outdoor Cultivation:

  • Thrives in both warm and cool climates, making it an ideal choice for temperate regions.
  • Handles rain, cold, and humidity exceptionally well, minimizing the risk of mold or disease.
  • Flowers early (August – September), ensuring a quick turnaround before harsh weather arrives.

Indoor Cultivation:

  • Easy to grow with minimal intervention—ideal for preservationists and breeders.
  • Best results with an 18/6 vegetative cycle, then transitioning to 14/10 and later 12/12 for flowering.
  • Can be left to reflower if seeking higher cannabinoid expression.

Nutrient Needs:

  • Moderate feeding throughout the cycle.
  • Avoid high-dose flowering stimulators to reduce hermaphroditic tendencies in late bloom.

Medical & Recreational Benefits

  • Potential for high-CBD selection, making it suitable for wellness applications.
  • Some phenotypes offer mild psychoactivity, great for light relaxation and mood enhancement.
  • Ideal for breeders looking to develop unique hemp strains with diverse cannabinoid ratios.
