The Complete Guide to Legal Herb & Hash in Japan

Back in Canada, there was nothing better than a slow afternoon with friends. Rolling a fresh joint, the paper crackling just a little as it twisted shut, the smell of some dank bud filling the room before we even lit up, and if we were lucky, a cheeky lil’ chunk of hash or two. It wasn’t just about getting high. It was about the ritual…grinding, rolling, passing, laughing, and the way certain strains could wrap you in a familiar, happy haze. I figured those days were over when I moved to Japan, but I was wrong. Now, with The Complete Guide to Legal Herb & Hash in Japan, I get to share how you can experience that same ritual here, completely legally.

Japan’s alternative cannabinoid scene has been quietly reinventing itself, especially since THC regulations tightened in December 2024. And right at the center of this new wave is Delta Farms — a brand that doesn’t chase trends, but nails authenticity. Their flower and hash feel like the real thing, minus the legal risk.

If you’ve been curious about legal herb or hash in Japan, this is your moment. And here’s a little treat to make it sweeter: use code MaryJane for 15% off sitewide at Delta Farms.

This review covers two of my favorites:

Grapefruit Kush CBXE + CBN Smoking Flower (10%, 5g pouch)
CRDH Permanent Marker Hash (50% CRDH, 1g)

I have been a fan of CBXE and CRDH together for a while. The euphoria they produce is not just additive; it is multiplied, proving that the entourage effect is real. Delta Farms nails the balance, texture, and terpene profile in a way that makes the experience something special.

Product #1: Grapefruit Kush CBXE + CBN Flower

The moment you open the pouch after wrestling with the child-and-adult-proof seal (trust me, you will earn your smoke), you’re greeted by a zesty, citrus-kissed aroma that’s unmistakably Grapefruit Kush. And it’s not just for show. Delta Farms infuses their flower with natural hemp-derived terpenes, so the scent and taste are as close to the real strain as possible.

Here’s what makes it stand out: unlike many so-called “legal buds” on the market, this isn’t random dried herbs sprayed with cannabinoids. Delta Farms’ flower is predominantly damiana, an aromatic, smoke-friendly plant that burns smooth. It’s infused using a proprietary, solvent-free method kept under lock and key to prevent copycats. The result? Cannabinoids are evenly distributed for consistent effects, with no harshness, just a clean, pure smoke.

Why it is exceptional:

Already ground. No grinder needed, no sticky mess. Just scoop and roll.
Perfect balance. CBXE for a mood-lifting, clear-headed buzz, and CBN for a calming, relaxing finish.
Complete kit. Comes with high-quality rolling papers — just add a filter.
Travel-friendly. Stylish 5g pouch that slips into a bag without drawing attention.

Best way to use: Roll it. This blend truly shines in a joint. The slow, even burn brings out the grapefruit tang and smooth herbal finish. You can bong or vape it, but the flavor and pacing of a joint make it a more authentic experience.

Product #2: CRDH Permanent Marker Hash

Hash in Japan is a rare treat. Most people here have never tried it, and even fewer have seen it done right. Delta Farms’ hash is dense, aromatic, and almost intimidating at first glance. Both the CBXE with CBN and CRDH versions are great, but today I’m talking about the CRDH Permanent Marker hash.

It leans toward Moroccan style with its uplifting high, and aromatic scent. One whiff hits you with a sweet, fruity smell and a hint of diesel, a terpene profile that’s both nostalgic and heady. It’s the kind of smell that instantly makes you think, oh, this is going to be good.

Why it is special:

50% CRDH content — that is 500mg in just 1g of hash.
Blended with CBD, CBG, and CBN for depth, balance, and smoothness.
Natural hemp-derived terpenes for an authentic, strain-specific aroma.
It has a sticky, pliable texture that is easy to work with once you know how.

Cannabinoid effect profile:

CRDH = euphoria and elation
CBD, CBG, and CBN = body relaxation and a smooth comedown

The best part? This is a rich, old-school and authentic smoking block that still meets every legal requirement in Japan.

How to Use Hash (Especially If You Have Never Tried It)

Since hash is new to most Japanese consumers, here is how to use it:

Crumble Method: Pinch off a small chunk, crumble it gently between your fingers, and sprinkle it evenly over your ground flower before rolling.
Snake Method: Roll the hash into a thin, even “snake” and lay it along the center of your joint. Wrap your flower around it and roll as normal. This gives you a slow, consistent burn.
Bowl Layering: Place flower in your pipe or bong bowl, add a layer of hash, then top with a little more flower. This prevents clogging and gives a layered burn.
Vape Method: Check your vaporizer’s manual. Hash usually needs higher temps than flower to vaporize properly.

For the most euphoric experience, pair the hash with one of Delta Farms’ smoking flower blends.

Why CBXE + CRDH Together Is the Dream Team

I’ve tried (and loved) each on its own, but something special happens when CBXE and CRDH meet. CRDH is like a spark that’s uplifting, creative, and social. CBXE is the best friend who dials everything up and adds a euphoric, immersive, slightly giddy feeling. Together, they create a wave that builds and holds, without the paranoia or edge of traditional THC.

If you miss the body-and-head balance of old-school herb, this pairing is as close as you’ll get in Japan while staying fully compliant.

The Legal Side (Peace of Mind Included)

Everything on the Delta Farms Japan site is THC compliant under Japan’s 12/12 regulations, which means less than 1ppm THC. They are crafted with hemp-derived cannabinoids and terpenes, so you can enjoy them without worrying about legal trouble.

For tourists and locals alike, that peace of mind is priceless. You get the ritual, the flavor, and the mood, all without the risk.

Final Thoughts

When I first heard “legal herb” in Japan, I didn’t think it could ever feel authentic. Delta Farms proved me wrong in the best possible way. Their Smoking Flower brings back the joy of rolling and savoring, and their hash is the closest I’ve seen to the real thing here.

Consider this your complete guide to legal herb and hash in Japan — now you can savor it for yourself.
