Most preserved cities were saved on purpose. Somebody formed a committee. Somebody else got a building designated. A third person wrote a grant proposal. The stone facades survived because organized people with clipboards fought to keep them standing.
Otaru was saved by going broke.
The Gateway That Got Left Behind
In the late 1800s, Hokkaido was Japan’s frontier. The Meiji government was colonizing the island in earnest — mining coal, catching herring, shipping goods south to Honshu. Otaru was the port that made it work. Every ton of coal, every barrel of herring oil, every crate of Hokkaido timber moved through Otaru’s harbor.
Foreign shipping companies arrived. Banks opened branches. Trading houses built headquarters. And because these were Meiji-era institutions modeling themselves on Western commerce, they built Western-style buildings. Stone. Brick. Heavy masonry with columns and cornices that looked like they’d been lifted from a Scottish banking district and dropped on the Hokkaido coast.
The canal was the center of it — a working commercial waterway lined with stone warehouses where goods moved from ship to storage to rail. The buildings along Ironai and Sakaimachi streets housed the financial infrastructure of Hokkaido’s early economy. The Nihon Yusen building, the Bank of Japan Otaru branch, the Mitsui Bussan warehouse — these weren’t decorative. They were the engines of a booming port city.
By the Taisho era (1912-1926), Otaru was one of the most important commercial cities in northern Japan. Population growing. Money flowing. Buildings going up in stone when most Japanese cities were still building in wood.
Then Sapporo happened.
The Long Decline
Sapporo had always been the administrative capital of Hokkaido. But through the early 20th century, economic power gradually shifted inland. Sapporo grew. Its rail connections multiplied. Its port — Tomakomai, on the Pacific side — began handling more cargo. Government offices consolidated there. Universities expanded there. Companies moved their Hokkaido headquarters there.
Otaru didn’t collapse. It deflated. Slowly, over decades. The big shipping companies wound down their Otaru operations. The banks consolidated to Sapporo branches. The warehouses along the canal stopped receiving goods. The population peaked around 190,000 in the 1960s and began a slide that hasn’t stopped. Today it’s about 105,000.
Here’s what matters about that decline: there was no money to modernize.
In postwar Japan, most cities that had economic activity tore down their old buildings and replaced them with reinforced concrete. That’s what happened in Sapporo, in Hakodate’s business district, in every city that could afford to rebuild. Japan’s default relationship with buildings is demolition. Old structures don’t gain value in Japan — they depreciate to zero and get replaced. I’ve covered this in earlier articles in this series.
Otaru couldn’t afford the demolition. It couldn’t afford the replacement. The stone warehouses along the canal were too expensive to tear down and too commercially irrelevant to justify new construction. So they sat. Through the 1970s, the 1980s, the 1990s — they sat. Empty or underused, weathering Hokkaido winters, but structurally sound because the Meiji-era builders had used stone and brick that could outlast centuries.
The canal district wasn’t saved by a preservation movement. It was saved by being forgotten.
What Benign Neglect Left Behind
Walk along the Otaru canal today and you’re looking at the consequences of an economic accident. The stone warehouses have been converted into restaurants, craft beer bars, glass workshops, museums. The canal itself — once filled in to its current narrow width as a compromise between preservationists and developers in the 1980s — is lined with gas lamps and walking paths. In winter, snow sits on the stone walls and the reflections in the canal water look like something from a Taisho-era postcard.
The Bank of Japan’s former Otaru branch is now the Bank of Japan Otaru Museum. The Nihon Yusen building is open for tours. The old stone commercial buildings on Sakaimachi Street house glass shops, music box stores, cafes. These aren’t reproductions. They’re the actual buildings, repurposed because someone finally realized that the thing Otaru couldn’t afford to destroy was the thing tourists would pay to see.
Otaru now ranks among Hokkaido’s top three tourist destinations, alongside Sapporo and Furano. Cruise ships dock at the port — international lines running routes through the Sea of Japan bring thousands of passengers who walk the canal, eat sushi, buy glass, and leave. Seasonal tourism peaks in summer and during the Snow Light Path festival in February, when hundreds of snow lanterns and ice candles transform the canal district into something that photographs don’t quite capture.
The Comparison That Keeps Coming Up
Foreign visitors — Europeans especially — tend to compare Otaru to small Mediterranean port cities. The hills rising behind the harbor. The stone buildings with their heavy facades. The narrow streets climbing from the waterfront. The sense of faded commercial grandeur from an era when this particular harbor mattered to the wider world.
I’ve heard Porto. I’ve heard Trieste. I’ve heard the smaller Ligurian towns where the pastel buildings climb the hillsides above a working fishing port.
The comparison is imperfect but not wrong. Otaru has the bones of a European port city — the stone, the topography, the architecture that announces former wealth. What it also has is a functioning JR train line to a two-million-person metro area thirty-five minutes away, seafood that would make a Ligurian fisherman weep, and property prices that make Porto look like Monaco.
What Otaru Is Not
I want to be specific about this because the tourism marketing can mislead.
Otaru is not a theme park. The canal district is beautiful and gets heavy tourist traffic, but it’s concentrated in a small area. Walk fifteen minutes in any direction and you’re in a regular Japanese city — residential neighborhoods climbing the hills, local shopping streets with pharmacies and hardware stores, elementary schools, dental clinics, the infrastructure of a city where 105,000 people actually live.
The tourists visit the canal. The residents live in the hills behind it. The two populations overlap for about six blocks along Sakaimachi Street and then diverge completely. I bought a house in the hills. My daily life involves the canal district about as much as a Manhattan resident’s daily life involves Times Square — I walk through it sometimes, I take visitors there, but it’s not where I buy groceries.
Otaru is also not rural. This trips people up. When they hear “declining Japanese city” and “cheap property,” they picture a mountain village with one bus a day and the nearest hospital two hours away. Otaru has hospitals. It has supermarkets. It has a JR station with rapid trains to Sapporo running every fifteen to twenty minutes. It has a working commercial fishing port. It has banks, post offices, city hall, a library, community centers, parks. The population is shrinking, but the urban infrastructure is intact.
The port is still active. Fishing boats go out in the morning and come back with squid, crab, herring, whatever’s in season. Sankaku Market at the train station sells the catch fresh. The harbor smells like diesel and salt water and fish, the way a real port does, as opposed to the curated version of a port that tourist towns manufacture.
The Population Story
Here are the numbers, because this is the part that matters for property buyers:
Otaru peaked at roughly 190,000 residents in the 1960s. Today it’s around 105,000 and declining by about 2,000 per year. The demographics skew old. Young people leave for Sapporo for university, for work, for the density of opportunity that a major metro provides.
This is the same demographic trajectory playing out across hundreds of Japanese cities. It’s the reason nine million akiya exist. It’s the reason you can buy a house in Otaru for the price of a used car.
But Otaru’s version of this story has a wrinkle that most declining Japanese cities don’t share: proximity to Sapporo and growing tourism. The population is shrinking, but the number of visitors is growing. The canal district draws millions of tourists per year. Cruise ships bring international money. The Niseko ski boom has spilled demand for accommodation eastward toward Otaru. These forces don’t reverse the population decline, but they create a floor under property values that purely rural towns don’t have.
Whether that floor holds or rises is the bet. I covered this in my article about how I bought my house — it’s a bet, and I’m living inside it.
Why I Picked This City
I could have bought cheaper property elsewhere in Hokkaido. I could have bought a nearly free house in a mountain village on Honshu. The akiya market is vast and the really cheap stuff is in places where nobody wants to live.
I wanted to live where I bought. That was the constraint that narrowed everything.
Otaru gave me a city I could walk around in, with stone buildings that have actual history baked into their walls, connected by a thirty-five-minute train ride to every urban amenity I could need. It gave me a harbor where fishermen still work, a canal where gas lamps still light up at dusk, and a neighborhood where the old woman next door brings me mikan oranges and I shovel her walkway when it snows.
The city preserved itself by accident. I moved here on purpose. Both decisions were driven by the same thing — a lack of better options that turned out to be the best option available.
