Why Is Nakayama Pass Famous for Ageimo?The Short Answer
Ageimo was created at Nakayama Pass in 1968 by a female employee looking for a simple snack for travelers. Inspired by the Japanese-style corn dog, she coated local potatoes in batter and fried them—and a Hokkaido road-trip legend was born.
Today, the snack is so closely connected with Nakayama Pass that the official roadside station says around 300,000 skewers are sold each year.
Why You Should Care
Imagine driving from Sapporo toward Niseko, Rusutsu, or Lake Toya.
The road climbs higher.
The city disappears.
Mountains surround you.
Then, at Nakayama Pass, drivers pull over for something surprisingly simple:
three fried potatoes on a stick.
No fancy seafood.
No expensive wagyu.
Just potatoes.
Yet for generations of Hokkaido travelers, stopping for ageimo has become part of the journey itself.
Once you know why it was created here, eating one feels less like buying a snack and more like joining a Hokkaido road-trip tradition.
The Story Behind Nakayama Pass Ageimo
Why Is Nakayama Pass Such an Important Stop?
Nakayama Pass sits on National Route 230, a major road connecting Sapporo with areas such as Rusutsu, Niseko, and Lake Toya.
At about 836 meters above sea level, it lies on the boundary between Sapporo and Kimobetsu and is the highest point along this section of Route 230.
For travelers leaving Sapporo, the pass feels like a gateway.
Once you cross it, the landscape opens toward the countryside around Mt. Yotei.
That made Nakayama Pass a natural place to stop, stretch your legs, enjoy the view—and eat something warm.
Who Invented Ageimo?
The story begins in 1968.
According to Japan’s Agency for Cultural Affairs, a female employee working at Nakayama Pass wanted to create an easy snack for people traveling between Sapporo and destinations such as Niseko, Rusutsu, and Toya.
Her inspiration came from an American dog.
In Japan, an “American dog” is a sausage on a stick covered in slightly sweet batter and deep-fried—similar to what Americans call a corn dog.
She had a simple idea:
What if the sausage were replaced with a local potato?
That idea became ageimo.
Why Potatoes?
Because this is Hokkaido.
More specifically, this is Kimobetsu, an agricultural town where potatoes have long been one of the local specialties. The town still lists potatoes among its major agricultural products today.
The modern Nakayama Pass roadside station also emphasizes potatoes grown around the Mt. Yotei area in its ageimo products.
So the original idea was perfectly suited to the place:
take one of the region’s most familiar crops,
turn it into something hot and filling,
and hand it to people in the middle of a long mountain drive.
Sometimes the best local foods begin with very practical ideas.
What Exactly Is Ageimo?
Ageimo literally means:
age = fried
imo = potato
But it is not a french fry.
A traditional Nakayama Pass ageimo uses whole potatoes covered in a soft, slightly sweet batter and deep-fried until golden.
A typical serving has three potatoes on one skewer.
The result is a simple contrast:
outside: warm, slightly crisp and gently sweet
inside: soft, fluffy potato
The official Nakayama Pass shop describes its version as using a secret “magic powder” for the coating.
Why Does Ageimo Feel Different From French Fries?
French fries are usually thin, salty, and crispy.
Ageimo is almost the opposite.
The potato stays mostly whole, so the center remains soft and substantial.
The batter also adds a gentle sweetness.
That makes it feel somewhere between:
a potato snack,
a corn dog without the sausage,
and a simple roadside comfort food.
It is easy to hold.
Easy to share.
And very satisfying after driving through the mountains.
That practical design is probably one reason the snack has lasted for decades.
Did Ageimo Exist Before the Roadside Station?
Yes.
This is a fun detail.
Ageimo was created in 1968.
But Michi-no-Eki Boyo Nakayama, the official roadside station where most travelers buy it today, was registered as a Michi-no-Eki in 1993.
That means the famous snack is about 25 years older than the roadside-station system at this location.
People were stopping at Nakayama Pass for ageimo long before modern “Michi-no-Eki” road-trip culture became what it is today.
Why Is the Roadside Station Called “Boyo Nakayama”?
The full name is:
Michi-no-Eki Boyo Nakayama.
The kanji for Boyo — 望羊 — refers to looking toward Mt. Yotei.
And that makes sense the moment you arrive.
On a clear day, the roadside station offers a beautiful view of Mt. Yotei, the nearly symmetrical mountain often nicknamed “Ezo Fuji” — the Mt. Fuji of Hokkaido. The official Hokkaido Michi-no-Eki guide specifically highlights the station as one of the best viewpoints for Mt. Yotei.
This creates the classic Nakayama Pass experience:
ageimo in your hand, Mt. Yotei in front of you.
How Popular Is Nakayama Pass Ageimo Today?
Very popular.
The official facility currently describes ageimo as its No. 1 item and says around 300,000 skewers are sold annually.
That number helps explain why ageimo has become much more than a convenient snack.
For many people in Hokkaido, it is tied to memories of:
family drives,
school trips,
ski trips,
weekend travel,
and journeys from Sapporo toward southern and western Hokkaido.
Food does not always become a regional symbol because it is complicated.
Sometimes it becomes famous because people eat it in the same place, on the same journey, generation after generation.
Is Ageimo Now an Official Part of Japanese Food Culture?
Yes.
In fiscal 2024, Nakayama Pass ageimo was selected for the Agency for Cultural Affairs’ “100-Year Food” program in the category for foods that communities hope to pass on for the next 100 years.
The program recognizes regional food cultures that have been developed and passed down within their communities.
That is remarkable for something invented as a simple roadside snack in 1968.
Ageimo went from:
“What can we serve hungry drivers?”
to
“This is a food culture worth preserving.”
Has Ageimo Changed Over the Years?
The classic version remains the star.
But the tradition is still evolving.
For example, in autumn 2026, the roadside station introduced a limited Premium Ageimo using three varieties of potatoes grown around Mt. Yotei, each finished with a different colored coating. The shop said the special version required two days of preparation and sometimes sold out in about 20 minutes.
The facility has even developed coffee specifically designed to pair with ageimo.
That is a nice reminder:
traditions do not have to stay exactly the same to survive.
They can keep their identity while continuing to change.
Why Does Ageimo Taste Better at Nakayama Pass?
Technically, you could fry a battered potato almost anywhere.
But that misses the point.
At Nakayama Pass, the food comes with:
a mountain road,
cool air,
a travel break,
Mt. Yotei,
and the feeling that you are leaving one part of Hokkaido and entering another.
That experience has been repeated by travelers since the late 1960s.
Ageimo is famous not only because of what it is.
It is famous because of where and when people eat it.
That is the real reason a potato on a stick became a Hokkaido icon.
My Favorite Way to Enjoy Ageimo: With a View of Mt. Yotei!
For me, one of the best experiences at Nakayama Pass is eating freshly fried ageimo while admiring the beautiful view of Mt. Yotei!
Mt. Yotei is often called “Ezo Fuji” because of its beautiful, symmetrical shape, which resembles Japan’s famous Mt. Fuji.
On a clear day, the mountain looks absolutely stunning from Nakayama Pass.
Enjoying hot, crispy ageimo while gazing at this magnificent mountain is, in my opinion, one of the best ways to experience Hokkaido!
Why Is Mount Yotei Called the Mount Fuji of Hokkaido?
Mt. Yotei’s beautiful, symmetrical shape has earned it the nickname “Ezo Fuji” (Hokkaido’s Mount Fuji).
But why does this mountain look so much like Japan’s most famous peak?

Final Thoughts
Why is Nakayama Pass famous for ageimo?
It did not begin with a marketing campaign.
It began with a simple problem.
Travelers were crossing a mountain pass.
They were hungry.
A woman working there wondered:
“What could we make for them?”
She looked at the corn-dog-style American dog.
She looked at local potatoes.
And in 1968,
she put the two ideas together.
That was enough.
Drivers stopped.
Families ate it.
Children grew up and came back.
More travelers stopped.
Decades passed.
And eventually, a simple fried potato became part of Hokkaido’s food culture.
Today, you can stand at Nakayama Pass with three warm potatoes on a stick and Mt. Yotei in the distance.
The recipe is simple.
The experience is not.
Ageimo is more than a fried potato.
It is part of the journey through Hokkaido.
