Two hours, no compromises: the chashu logic at Men-Eiji

Men-Eiji's gyokai-tonkotsu has built a small but loyal audience across Sapporo, and one of the most common questions sent to the kitchen is why the chashu cooks for exactly two hours. It is a fair thing to ask. Most ramen counters either braise pork for far longer or sous-vide it overnight, treating the slice almost as an afterthought once the broth has done its work. At Men-Eiji, the pork roll is timed alongside the seafood stage of the broth itself, which is a different kind of discipline. Watching chef Jun Furukawa lift the roll out of the pot at the one-hundred-twenty-minute mark feels closer to a kitchen ritual than a typical prep task.

The two-hour window is rooted in a simple observation about how protein and broth talk to each other. Pull a roll sooner and the edges dry out by the time a customer is four or five bites deep into a bowl. Leave it another thirty minutes and the ribbed fat starts rendering into the broth, dimming the seafood character of the liquid. The narrow band in the middle, sustained with precision, gives the diner a slice that still chews like pork rather than dissolving like stewed wool.

For travellers planning a Sapporo trip after a season of ramen crawls through Surry Hills, that level of discipline is the kind of detail worth booking a flight around. Reading a side-by-side comparison of the two branches before the flight helps turn the philosophy into something edible once the plane lands at New Chitose.

The broth alliance behind the two-hour window

The broth at Men-Eiji runs on a night-before timeline. Pork back bones and trotters go in first, brought to a hard rolling boil for the early hours, then dialled back once the collagen starts releasing. This is what gives the liquid its weight. Only after the pork bones have surrendered their connective tissue does the gyokai layer begin: niboshi, katsuobushi shavings, dried flounder, scallop shells. That stage arrives at the two-hour mark of a new service day, which is exactly the same window the chashu is timed against.

A chashu dropped into already-loaded broth cooks differently than a chashu braised in clean water. The fatty acids and gelatin from the pork bones create a thermal shortcut, softening the muscle fibres without steam-blasting them. By the end of two hours, the protein reads as tender but still has bite. A roll left another thirty minutes starts to render its ribbed fat into the pot, smearing the seafood character the gyokai side is trying to protect.

This is also why the kitchen never braises a pork roll ahead of service and then reheats it for lunch. Reheating reverses the moisture gradient built up during the original two-hour cook. Fresh from the pot, the slice retains enough internal juice that even a slow eater working through a thick broth can finish the last piece without chasing it with a napkin.

Inside two hours of heat

The two-hour window is not a single chemical event. It is a layered process where several changes happen almost in parallel. Looking at the protein closely, three stages dominate the cut from start to finish. The kitchen watches each one and pulls the pot the moment the second reaches its plateau.

What changes inside the pork

Pulling the roll at any point before the second stage finishes leaves a slice that looks cooked but feels tough once chewed. Holding the pot another forty-five minutes lets the intramuscular fat cross the line, and the slice starts tasting like pulled pork rather than chashu. Two hours sits in the band where the salt has reached the centre, the collagen has converted, and the fat has barely shifted. That convergence is what the kitchen is really chasing.

For diners who have eaten across Melbourne's late-night AC/DC Lane counters or spent a winter arvo queueing through Fortitude Valley, the difference between a one-hour braise and a two-hour braise lands hard in the mouth. The shorter version feels polite. The longer version feels like the cook gave up. The two-hour version asks the pork to do something specific and lets it do that thing all the way through.

Aroma, edge, and the plate-to-bowl connection

Aroma is harder to measure than texture, but the kitchen reads it constantly. During the second hour of braise, the chashu begins to pick up the marine vapour rising off the simmering seafood stock. That vapour carries small amounts of scallop-shell minerality and dried-flounder sweetness straight into the surface fat of the pork. By the time the slice is lifted, blotted briefly, and arranged on the bowl, the chashu has already been seasoned twice: once from inside, once from above.

This secondary seasoning matters more in gyokai-tonkotsu than in a soy-shoyu or miso bowl. The pork bone layer of the broth is rich, and without a top-note lift the whole bowl trends heavy. The two-hour chashu compensates by arriving at the counter already carrying those top notes. The diner does not consciously identify them, but the bowl reads brighter than the ingredient list suggests, which is one of the reasons Men-Eiji's bowls have travelled well to international pop-ups.

That approach scaled cleanly into the takeaway format used for interstate dates, including a recent Adelaide Hills weekend where the broth travelled cold-packed and the chashu was finished on a small gas pot on site. The two-hour timing carried over without modification. A shorter or longer braise would have required the team to retune everything from broth salinity down to noodle firmness.

Reading the same logic across both Sapporo counters

The two-hour braise is taught the same way at Hiragishi BASE and at Duck Ramen EIJI, with the same dipping stations, the same internal probe temperature targets, and the same lift time. The two counters diverge on other things: seating, sides, hours, signature fat base. Side-by-side, the working details look like this.

Same chashu discipline on both sides of town. Different contexts to eat it in. Hiragishi BASE runs a longer dinner cut and a more traditional broth-first pour. Duck Ramen EIJI leans into duck-fat for the evening queues that form after the Chuo-ku cocktail bars close.

A traveller with only one night in town should pick the counter that matches their evening shape. A dinner-first visitor flying out the next morning will get more out of Hiragishi BASE. A late lunch with a daytime itinerary fits Duck Ramen EIJI better, since the kitchen closes at 15:30 and the queue thins by 14:00 on weekdays.

What two hours on the tongue actually feels like

Inside the bowl, the chashu does most of its work across three bites. The first bite confirms the surface aroma. The second proves the tenderness. The third is where the broth and slice settle into each other, where the salt and the seafood carry have moved into the fat and now taste like they belong together. A chashu that missed any of the three reads as slightly underdone in a different way each time, even if a less trained diner would call them all the same.

A bowl loaded with too many competing toppings drowns the chashu. The two-hour investment only pays off if the slice is allowed to lead. Walking up to the ticket machine with a stripped-down order is almost always the better move, and a few combinations tend to give the slice that room.

Pairings that hand the slice the lead

That third bite is what the kitchen tastes every time a new batch comes out of the pot. If it lands muted, the team looks at the chashu first. Pulling earlier often fixes the muted finish. Pulling later fixes a too-soft bowl. The two-hour clock is less a recipe and more a feedback loop, adjusted all day by people standing over a probe thermometer.

Two Sapporo stops can realistically fit into a four-day Hokkaido itinerary, especially for travellers flying in from an Australian winter already halfway plotted. Most visitors arriving at New Chitose in the afternoon take the JR into Sapporo Station and have the rest of the day plus one full day inside the city before heading to Niseko or Furano. Lunch on day one at Duck Ramen EIJI, dinner on day two at Hiragishi BASE, and the rest of the time chasing coffee, ramen-adjacent izakaya food, and the late-night snack culture Sapporo runs into the small hours. For a traveller already mapping Hobart and Sapporo into the same winter calendar, slot one of these bowls in before the powder crowds arrive and let the discipline of a two-hour chashu reset what ramen is supposed to taste like. The seats at both counters are tight, the lift times are real, and the broth clock does not pause for anyone who turns up late.
