Roadside Station Rumoi: The Too Firm Pudding and Herring Souvenirs

The Ororon Line is the coast road up the Sea of Japan side of Hokkaido, from Otaru to Wakkanai. If you drive up from Sapporo on the expressway to join it at Rumoi, Roadside Station Rumoi is your first stop off the expressway: four minutes from Rumoi IC (interchange), where the coast road begins. It has toilets open around the clock, and two things worth buying, Rumoi's "too firm pudding" from a vending machine and herring souvenirs.

1What is Roadside Station Rumoi?

Roadside stations (michi-no-eki) are Japan's public rest stops on ordinary roads, with free parking, toilets and local food. In Rumoi, the roadside station is a large lawn park, Funaba Park, beside the harbor. When I went in October 2023, the stone sign at the edge of the lawn had a sightseeing map of Rumoi on it.

Around the park are the main building with toilets and a tourist desk, an indoor play area for children called Chairumo, a park golf course, a dog run, and an outdoor activity building with a mont-bell store (official website, as of November 2026).

2Where do you buy the too firm pudding?

The station's best-known treat is the too firm pudding (katasugiru purin) made by Lumond, a Rumoi sweet shop that also runs Rumo Café at the roadside station. It is sold only from a vending machine. When I went in October 2023, it filled the middle row of the orange "Nanikore?!" vending machine, in glass jars at 500 yen each, with jars of chocolate cake and tiramisu above.

According to Rumo Café's notice of October 5, 2026, the orange machine is out of order, and the pudding is now sold from the blue machine with a Japanese pattern just to its right (Rumo Café's notice, as of November 14, 2026). Look for the sign saying 固すぎるプリン コチラです (too firm pudding here).

What does it taste like?

True to its name, it holds its shape on the spoon, edges and all. In the mouth, though, it is light and fluffy, almost like a soufflé, and nothing like a smooth, wobbly custard.

3Herring and herring roe souvenirs

Rumoi is known for herring and herring roe (kazunoko), and the roadside station sells both. My pick, sold in the shop inside the station building, is herring simmered in sweet soy sauce (nishin kanroni): eat it as it is with rice, or lay it on hot soba noodles for herring soba.

The same machine also sold local food. In October 2023 it had jars of herring roe (1,000 yen), matsumae-zuke pickles made by a herring roe maker (500 yen), and herring pie from Roadside Station Obira Nishin Banya, about 30 minutes north of Rumoi (500 yen). The orange machine is out of order now (as of November 14, 2026), so these may not be on sale.

4Can you eat there?

The main building has two counters: Musashiya, for soba and udon, and Funaba Café, for soft-serve ice cream and coffee. Musashiya serves herring soba and Rumoi's station lunch box, the nishin oyako bento, with sweet simmered herring and herring roe. Both are open 9:00 to 16:00; Musashiya is closed on Tuesdays and Funaba Café on irregular days (official website, as of November 2026).

On my day trip along the Ororon Line, Rumoi was the morning break. I went on to Cape Ogon, five minutes away across the harbor, and then had lunch in Mashike, about 30 minutes south along the coast, at a seafood restaurant known for sweet shrimp.

That restaurant is Fukuyoshi in Mashike, where I had sweet shrimp and scallops on rice.

5Which Ororon Line roadside station should you stop at?

There is a roadside station every hour or so of driving along the coast. Which one you stop at depends on which way you are driving.

6How to get there

From Sapporo: about two hours without stopping, or two and a half with a break at a service area on the way. Take the Do-o Expressway toward Asahikawa, keep left for Rumoi at Fukagawa JCT (junction), and leave at Rumoi IC, the end of the Fukagawa-Rumoi Expressway. Go straight from the exit, and turn left across the bridge you see on your left; the roadside station is just over it. Iwamizawa SA and Sunagawa SA (service areas; Sunagawa is the northernmost in Japan) are good stops on the way; at Sunagawa, try the Iwase Farm gelato.

From New Chitose Airport: 169 km, about 2 hours 20 minutes to Rumoi without stopping, 20 minutes longer than from Sapporo. Take the Do-o Expressway toward Sapporo and follow the signs for Asahikawa at Sapporo JCT; from there it is the same route (official website, as of November 2026).

7How long to stay

Thirty minutes is enough for the toilets, the pudding and some souvenirs. On my day trip, I left Sapporo at 8:00 from Shin-Sapporo, on the east side of the city, reached Rumoi at 10:30 and left for Cape Ogon at 11:00. Allow an hour if the children want to play in the park or in Chairumo.

8Hours and parking

The main building closes at 17:00; the food counters inside close at 16:00.

Hours and parking are as of November 2026. Check the official website before you go.

9Near Roadside Station Rumoi

Cape Ogon is just across the harbor, five minutes away by car: a rocky shore looking out over the Sea of Japan, known for its sunsets.

If you are going all the way north, Rumoi is also the first break on my drive to Wakkanai, which ends with the sunset at Cape Noshappu.
