Why Is Cranberry’s Sweet Potato So Famous in Obihiro?The Short Answer
Cranberry’s Sweet Potato has been a signature dessert in Obihiro since the shop opened in 1972. It stands out because the sweet potato filling is served in a real sweet potato skin, keeps the natural flavor of the ingredient, and is sold by weight rather than at one fixed price.
More than 50 years later, it is still one of the sweets most closely associated with a trip to Obihiro.
Why You Should Care
Obihiro is famous for food.
Pork bowls.
Dairy products.
Local sweets.
And among those sweets, one dessert looks almost too simple to become a local icon:
a very large sweet potato.
But this is not an ordinary baked sweet potato.
Cranberry has been making this dessert since the company was founded in 1972, and the store has spent decades introducing it to customers both in Hokkaido and across Japan.
Knowing that story makes buying one in Obihiro feel less like picking up dessert—
and more like tasting part of the city’s food history.
The Story Behind It
How Did Cranberry’s Sweet Potato Begin in Obihiro?
The story started on October 7, 1972.
The business originally opened in Obihiro as a Western-style confectionery shop called Andersen.
Its Sweet Potato was already a signature product from the beginning. In 2000, the company changed its name to Cranberry, the name travelers know today.
That means the dessert was not created later as a tourist souvenir.
It has been part of the shop since day one.
More than half a century later, Cranberry still describes it as the product that represents the company.
Why Does Cranberry Use a Real Sweet Potato Skin?
This is the first thing you notice.
Instead of placing the dessert in a paper cup or pastry shell, Cranberry uses the actual sweet potato skin as the container.
The company says it tries not to over-process the ingredient, focusing instead on bringing out the natural flavor of the sweet potato. Because sweet potatoes harvested in different places and seasons have their own flavor characteristics, the raw ingredient itself remains an important part of the dessert.
The result looks rustic rather than perfectly uniform.
And that is part of its charm.
One important tip for travelers: Cranberry says the skin is used as a container and does not recommend eating it.
Why Is Cranberry’s Sweet Potato Sold by Weight?
This is another unusual feature.
At Cranberry stores, Sweet Potato is not simply sold as:
“One piece = one price.”
Instead, it is sold by weight.
As of September 2026, the official store price is ¥270 per 100 grams.
So the final price depends on the weight of the piece you choose.
For overseas travelers, this can be a fun surprise.
You point to the Sweet Potato you want, the staff weighs it, and that weight determines the price.
It feels more like choosing something fresh at a market than buying a perfectly standardized factory-made dessert.
Why Does It Taste Different From an Ordinary Sweet Potato?
Cranberry describes its Sweet Potato as having a mild sweetness and emphasizes preserving the natural taste of the sweet potato rather than adding excessive sweetness.
You can also enjoy it in two different ways.
Warm it slightly, and the texture becomes soft and comforting.
Or chill it in the refrigerator for a cooler, firmer dessert.
Cranberry officially recommends both styles.
If you buy one during your Obihiro trip, trying part of it cold and warming the rest later is an easy way to experience both.
How Did an Obihiro Dessert Become Famous Across Japan?
Cranberry did not keep its Sweet Potato only in Obihiro.
Beginning in the 1980s, the company started taking part in Hokkaido food fairs at department stores around Japan.
At these events, staff demonstrated the making and selling of the Sweet Potato directly to customers.
This was important.
People who had never traveled to Obihiro could discover the dessert in Tokyo, Osaka, or another city.
Then they associated it with:
Hokkaido → Tokachi → Obihiro → Cranberry’s Sweet Potato.
Decades of these events helped turn a local confection into a dessert known far beyond eastern Hokkaido.
Why Is Obihiro Such a Good City for Sweets?
Cranberry is only one part of Obihiro’s larger sweets culture.
The Obihiro Tourism and Convention Association even promotes a sweets tour connecting local bakeries and confectionery shops around the city. Cranberry is included as one of the stops.
That makes sense in Tokachi.
The region is strongly associated with agriculture and dairy farming, and food has become an important part of the visitor experience.
So when you explore Obihiro, dessert does not have to be something you eat after sightseeing.
Dessert can be the sightseeing.
Where Is the Easiest Place for Travelers to Buy It?
Cranberry currently operates five stores in Obihiro and neighboring Makubetsu.
For travelers using trains, the easiest option is usually the Esta Obihiro store, located inside the west wing of the JR Obihiro Station complex. The official store page lists its hours as 8:30 a.m.–7:00 p.m.
If you want to visit the original downtown shop, クランベリー本店 is located at Nishi 2-jo Minami 6-chome and is currently listed as open from 9:00 a.m.–8:00 p.m.
That means you can easily add a Sweet Potato stop before or after exploring central Obihiro.
Can You Take Cranberry’s Sweet Potato Home?
Yes—but plan carefully.
For store-bought Sweet Potato, Cranberry recommends refrigeration and says the best-eating period is generally about 2–3 days after purchase, depending on storage conditions.
This makes it better suited to:
- eating during your Hokkaido trip
- enjoying at your hotel
- taking home if your journey is short and you can keep it cold
There is one important current update.
As of September 2026, Cranberry has temporarily suspended online Sweet Potato orders and furusato-tax orders because increased demand has made it difficult to secure enough raw materials. The restriction began on May 26, 2026, with no announced end date yet.

Don’t Miss Cranberry’s Delicious Soft-Serve Ice Cream
Cranberry is famous for its sweet potatoes, but there’s another treat I highly recommend—soft-serve ice cream!
Its smooth, creamy texture and delicious flavors make it a perfect dessert while exploring Obihiro.Different flavors are available depending on the store, so it’s worth checking the menu when you visit.
My recommendation: Don’t leave Cranberry without trying both the sweet potato and the soft-serve ice cream!
Why Is Hokkaido Ice Cream So Good?
Hokkaido is famous for its delicious dairy products, and ice cream is no exception!Discover why Hokkaido’s ice cream is so creamy and what makes it special.
