Broth worth the wait.

48-hour pork bone tonkotsu. House-pulled noodles. No shortcuts, no stock cubes, no apologies.

Since 2019

Started with one pot and a 12-seat counter.

Kōji started because we couldn't find the ramen we wanted in Portland. Not the watered-down, 20-minute stock version. The real thing — bones simmered for two full days, noodles pulled fresh every morning, tare aged in-house using kōji fermentation.

We opened on SE Division in 2019 with a tiny kitchen and no reservations. Word got around. Now we seat 48 and still run out of tonkotsu by 9 PM most Fridays.

Word of mouth

Straight from the counter

★★★★★

We come here every Friday after work. The tonkotsu is ridiculous — thick, rich, and they don't skimp on chashu. My 6-year-old drinks the broth like soup. Every time.

Tried every ramen spot in Portland over the past two years. This is the one I keep coming back to. The spicy miso will clear your sinuses and your soul. Counter seats are the move — you can watch them pull the noodles.

Ordered the tantanmen on a cold January night. Perfect. The sesame and chili oil hit different when it's 38 degrees outside. Also the karaage is dangerously good.

Brought my parents here from Tokyo. My dad said the broth reminded him of a shop in Hakata he used to go to in the 80s. That's the best review I can give.
