Shipping the Soul of Sapporo: Men-Eiji's Broth Goes Global

Tucked away in the residential lanes of Toyohira-ku, Men-Eiji has spent more than a decade refining a single obsession: a cloudy, fragrant gyokai-tonkotsu broth built from pork bones, dried sardines, scallops, and a measured pour of bonito oil. Founder Jun Furukawa, the chef behind both Men-Eiji Hiragishi BASE and the sibling Duck Ramen EIJI counter, has long argued that this broth is more sauce than soup, a building block rather than a backdrop. As demand from overseas fans grew louder each year, the natural next step seemed obvious: bottling the broth and shipping it to pop-ups abroad.

Bringing gyokai-tonkotsu across the equator, however, quickly revealed itself to be a different kind of cooking. Air freight lanes to Sydney, Melbourne, and Los Angeles run for fifteen hours or more, customs brokers in destination countries require airtight paperwork, and Australian biosecurity officers in particular treat any animal-derived liquid with intense skepticism. Add in the fact that hot broth cannot be transported as broth at all — it has to be cooled, sealed, and confidently reimagined — and the gentle romance of "doing a pop-up" starts to look a lot like project management.

For Men-Eiji, the stakes are also cultural. Australian diners have become some of the most demanding ramen connoisseurs outside Asia, with queues for places like Ippudo, Gumshara, and a dozen Melbourne CBD counters stretching out the door most evenings. They expect depth, salt balance, and the unmistakable scent of the sea. Reproducing that off the back of a cold-chained box, in a borrowed kitchen, half a world away from Sapporo, is a puzzle the team has had to solve one batch at a time.

This is the story of how Men-Eiji approaches that puzzle, the setbacks that forced new thinking, and what the process has taught the kitchen about staying true to its origins while making itself portable.

The Broth as the Brand, Not the Menu

Jun Furukawa rarely talks about toppings first. When he describes the Sapporo kitchen to visitors, he talks about the kettle, the rolling boil, and the twelve-hour skim. That hierarchy matters when the broth leaves Japan, because nothing else on the menu can rescue a bowl if the foundation fails. A handful of noodles, a soft-yolked egg, three slices of chashu — these are accents. The broth is the whole performance.

Exporting, then, is less a logistics exercise and more a translation problem. Fish and pork bones behave differently once they are boiled down, chilled, frozen, thawed, and reboiled in tap water thousands of kilometres from the original. Calcium and magnesium ratios shift. Collagen breaks down at different rates. Salt perception dulls slightly after time in cold storage. Each of these small chemical nudges pushes the flavour off-centre, and customers in Brisbane or Perth can taste the difference as quickly as the chef.

The team's answer has been to treat exported broth not as finished product but as a concentrate. Skim volumes at Sapporo tend to be reduced further before bottling, with a final adjustment of soy and fish sauce to be folded in at the destination. That compromise keeps the umami spine intact while leaving room for last-minute calibration in an unfamiliar kitchen.

Cold Chain Logistics Across the Southern Hemisphere

The physical journey is unforgiving. A pallet of frozen broth usually rides from Shin-Chitose through Narita or Haneda, hops to Singapore or Hong Kong, and lands at Sydney, Melbourne, or Brisbane a day later. Carriers that handle dumplings and premium wagyu for high-end restaurants tend to be reliable, but drayage, slot bookings, and last-mile refrigerated trucking still go wrong with uncomfortable regularity. A missed connection on the tarmac can leave a container of -18°C stock sitting in a warm customs bay for hours.

For Men-Eiji, the response has been to ship smaller, more frequently. Three or four boxes of just-in-time broth travel every pop-up rather than one massive crate. It costs more per kilogram, but it allows the team to recover gracefully when weather, strikes, or the occasional volcanic ash cloud scrambles the route. Each box is also double-sealed: a primary food-grade bag tucked inside a leak-proof drum, with a tamper-evident strap for the Australian border agents who will inevitably open it.

Australia's Biosecurity and Import Reality

No country on the Pacific Rim is fussier about food imports than Australia, and ramen broth falls right in the middle of the rules. The Department of Agriculture requires full disclosure of every ingredient, every fishery source, and every animal origin point on a meat and seafood product. A single mislabelled tin of dashi powder, or an absence of evidence that bonito was harvested outside a restricted zone, can mean a whole shipment being re-exported or destroyed on the dock.

Men-Eiji's team learned this the hard way during an early Melbourne visit, when a borderline scallop sourcing question pulled a container out of rotation for nine days. Since then, they pre-clear paperwork with an Australian-based broker, attach country-of-origin certificates for every imported seafood component, and keep a printed ingredient deck in the truck for any random inspection. Diners visiting the Sapporo flagship address often assume the broth travelled without drama; the paperwork backstage tells another story.

There is also the question of how broth is classified at the border. A pure liquid generally draws different scrutiny than a shelf-stable concentrate, and heat-treated products can sometimes avoid certain inspections entirely. Each route carries trade-offs in shelf life, flavour fidelity, and how confidently a chef can stand behind the bowl being served.

Rebuilding the Bowl Far from Sapporo

Even with the broth safely thawed, the work is only half done. Australian tap water is famously soft in Melbourne and reasonably hard in parts of Sydney, and that single variable changes how soy, salt, and fish sauce read in a bowl. The Men-Eiji crew now travels with a portable TDS meter and a few sachets of mineral blend to nudge the water back toward what their Hokkaido kettle produces. Locals notice the difference without being able to name it.

Noodles are another puzzle. Fresh ramen noodles do not survive international cold chain well, so the team partners with local Australian flour mills in advance. Sydney's heritage pasta houses and Melbourne's artisan producers have been surprisingly willing to adjust hydration and resting times for a guest menu. Egg content stays high, kansui is sourced locally, and resting is held back a few extra hours to mimic the texture of a Sapporo morning batch.

Equipment brings its own surprises. Australian three-phase power can differ from Japanese wiring, and most borrowed kitchens expect induction rather than gas. The team now travels with portable burners and a flat-top that matches the temperature curve of their home stoves, so the final tare reduction behaves the same way it would in Toyohira-ku.

Trust, Crowds, and the Soft Skills

Pop-ups live or die on word of mouth, and Australian food media has little patience for lukewarm ramen. A bad tray of broth, a slack noodle cook, or a queue that grumbles past ninety minutes can doom a guest run before the second sitting. Men-Eiji addresses this by limiting tickets, posting FAQ notes about batch size, and letting regulars from venues like Ramen O-San and the Tokyo Tina kitchens pop in for a tasting before doors open.

Language plays a small but real role too. Staff learn the soft Australian habits — saying "no worries" instead of "daijoubu", saying "thanks heaps" instead of "arigatou", and never asking a punter if they're "right" because someone, somewhere in Brisbane or Adelaide, has already made that joke too many times. It is a small courtesy, but it shifts the pop-up from foreign concept to friendly neighbourhood kitchen.

There is also an emotional layer. Furukawa likes to remind the team that an overseas pop-up is rarely a financial win for a small Hokkaido brand. It is brand-building, a love letter to diaspora customers, and a quiet advertisement for the Sapporo home base all rolled into one brisk weekend.

Practical lessons from the road

Looking ahead, the team is exploring shelf-stable retort processing for select broths destined for non-refrigerated pop-up carts in Melbourne laneways, where back-of-house space is tight. They are also testing concentrated tare sachets that travel light and rehydrate with boiled water in seconds. Both moves would compress the cold-chain headache and let the chefs focus on noodles and hospitality. The broader lesson sits at the heart of any authentic export effort. Liquid broth is fragile, but the brand is portable when treated with care. Australian fans, who already make up the largest international following outside East Asia, appear willing to embrace the imperfection of a pop-up bowl as long as the soul of the broth is preserved.

To experience the broth in its home setting before the next international run lands, stop by the Men-Eiji Hiragishi BASE page for opening hours, the seasonal menu, and the address in Toyohira-ku. Tickets to the upcoming Australian events will be released soon through the brand's social channels — keep an eye out and book early, because the queue always forms well before service begins.
