In praise of…The ghost highway

Leaving Osaka and heading for Kyushu, the driver is presented with the option of two highways running broadly parallel: the Sanyo Expressway, which hugs the populous Pacific coast, and the Chugoku Expressway, which barrels across the low rolling mountains of the middle of this westernmost region of Honshu. Ever eager to take the road that seems less travelled, I opted for the Chugoku.

Once past Kobe, 40km outside of Osaka, the traffic melted away, and I settled back to enjoy the ride into the sunset. On and on the road unspooled, up and up the kilometers from Osaka mounted, sparser and sparser the traffic became. Why on earth was this road built, I wondered to myself. Some 300km out of Osaka, the Chugoku veers south to clip the north of Hiroshima City, the lunges west again beyond the Hiroshima North junction through a parade of tunnels. It began then to dawn with faint foreboding that I was essentially the only thing heading west, and at 7.10pm that Saturday evening, with dusk descending, I started counting off the minutes that elapsed before passing, or being passed by, other road users. Five minutes went by, then 10: I passed a pair of cars. Reset the stopwatch: five, 10, 15, 20, 25 minutes… At 7.46pm I passed another pair of cars, and then two more before, at 8pm, I turned off for Yamaguchi City, 475km out of Osaka, to find a place to stay for the night. In 50 minutes, I had covered about 80km…and met with just six westbound vehicles.

Returning from Kyushu, I decided to photo-document the otherworldly desolation of the Hiroshima-Yamaguchi stretch of the Chugoku, dropping in at every parking area and service area and pulling on to the hard shoulder every 10km or so for a snapshot of the state of the road, as long as the light held out, for the Chugoku is no ordinary road to nowhere, built to keep local construction companies afloat, but a full-bore four-lane expressway, at 540km the second longest in the whole of Japan, linking its second most populated city, Osaka (prefectural population of nearly 9mn) with its second most populated island, Kyushu (population of over 13mn).

445km out of Osaka (444km, to be pedantic—the 444km marker is just visible in the central reservation)

435km out of Osaka

The Kano service area: both of its gas stations closed in 2005 and no traces of them remain. Service areas are supposed to offer 24hr shops and restaurants, but those at Kano are no longer open at night, leaving only vending machines and toilets.

The Yoshiwa service area

Abandoned gas station at the Yoshiwa service area, closed in March 2009. The westbound gas station closed in November 2008. There is now no fuel available on the Chugoku for some 150km, between Mito (487km from Osaka) and Asa (340km from Osaka). In all ignorance, I ask: is there anywhere else in the developed world where highway gas stations are being closed down?

375km out of Osaka, now engulfed in darkness but still bereft of roadway companions in either direction. Having already driven some 800km that Sunday and needing to find accommodation for the night, I gave up on documenting the silences and absences of the Chugoku after 100km of desertion, case proven.

So what accounts for the Chugoku’s voids? To answer that question, we have to rewind to the 1960s and the dawn of Japan’s motorization, when the powers that were decided, reasonably enough, that an expressway would be needed between Osaka and Kyushu—and then proceeded to put it in the wrong place. The Chugoku was built in stages between 1970 and 1983, when it was fully opened, but for roughly 400km it runs through hill and dale and small farming settlements, the biggest centers of population it passes through being Tsuyama in northern Okayama (around 100,000 people) and Miyoshi in northern Hiroshima (around 60,000 people). Like nascent expressway planners the world over, I sense, the road builders failed to realize that most traffic on their creations would be local.

Planning then began for the Sanyo Expressway, linking Kobe and Yamaguchi, but this time right through the center of cities such as Himeji (over 500,000 people), Okayama (over 700,000 people), Fukuyama (nearly 500,000 people), and Hiroshima (nearly 1.2mn people). Construction work began in 1982 and the expressway, in all its 450km or so of glory, was completed in 1997. Traffic immediately drifted south from the Chugoku to the Sanyo, the Chugoku not helped by its relative age, which means a dearth of tunnels, an abundance of tight corners, and a ridiculous 80km/h (50mph) speed limit along most of its length, falling as low as 50km/h (30mph) at one point, which must surely be the lowest mandated speed limit in the world for a full-scale highway—thankfully, it’s gleefully ignored and unenforced.

What does the future hold for the Chugoku? Greater loneliness is the only conceivable answer. Traffic on much of it is currently falling by around 2% a year, I guesstimate, caused by ageing and depopulation in the rural communities it largely serves: the population of Tsuyama is projected to slide 18% from 2005 to 2035 and of Miyoshi 29%, to say nothing of the smaller towns and villages along the way, where population declines will be still more dramatic. The San’in expressway on the Sea of Japan side of Chugoku is due to be completed sometime this decade, as long as the money holds out, draining still more traffic from the Chugoku. I suspect that by mid-century, all things being equal, large stretches of the expressway will finally be judged unviable and left to rot.

In the meantime, though, let’s raise a toast to the joys of the Chugoku, over 400km of delightful motoring through pine glades, across ponds, and past picturesque farmhouses, with nary another motorist in sight. One word of warning, though: the highway patrol cops are very active for at least the first 100km out of Osaka, so stick to within 20km/h of the speed limit, as you wouldn’t want to get caught by the fuzz on the ghost highway.

Postscript for traffic nerds and the curious: I did some digging around to see if I could quantify just how empty the Chugoku was. Fortunately, it’s not that difficult, as Wikipedia Japan carries the results of an FY3/06 census by the Ministry of Transport for almost all of Japan’s highways, and we can I think safely assume that, barring the odd typo, the information will have been inputted honestly.

At its most congested, just out of Osaka, the Chugoku carries about 105,000 vehicles per 24hr spell, making it just about as packed as any highway in Japan. At its least congested, on the Okayama-Hiroshima border, slightly to the east of the stretch I chose to document, it carries fewer than 5,000 vehicles a day, less than 1/20th of the volume; between Hiroshima North and Yamaguchi the volume is 10,000-13,000 vehicles a day, which still, at 10,000, divided by two (for westbound and eastbound traffic) and then divided by 24hrs, is only about 200 vehicles an hour, or 3.5 every minute, averaged out across the day, which means many fewer in the off-peak periods. Even the Akita Expressway carries more traffic for most of its length than the Chugoku’s least trafficked parts do.

The ghost highway prize will eventually go, I suspect, to the Doto Expressway in Hokkaido, which will link Chitose south of Sapporo and Kushiro in the east, some 260km away; it is due for completion in 2013 or thereabouts, so the volume numbers we have at the moment are tentative, but about 1,500 vehicles per day on average over large stretches seems like a reasonable assumption. One every half a minute in each direction, far fewer at night.

FWIW, I got my traffic decline projection from the same source—traffic on the Chugoku fell by 2.4% from FY3/02 to FY3/03, while on the Meishin between Nagoya and Osaka it fell 1.2% and on the Tomei between Tokyo and Nagoya it fell 0.5%. That might have been amid the tail-end of a mild recession, but there’s no real reason to think those percentage declines are not much larger now.

  1. Welcome back! What a great start, you really manage to turn the void into words, so to speak😉
    … this might not help Japans economy much, but is highly entertaining.

    • Hey Juergen, thanks for the generous praise! Much, much more to report, but I thought I’d start with an easy one~

  2. Oh man, I remember bits of that road close to Tsuyama on the way to a place that teaches you how make traditional Japanese paper.

    Tsuyama really does have that small town feeling.

  3. Love it! The Chugoku Expressway looks very enticing – virtually no cars! Fantastic pictures. It looks a bit like Hokkaido – first rate roads, very few users. Is the Chugoku more expensive than the Sanyo? Just wondering…

    Regarding highway gas station closures in developed countries, there may be a few along highways in remote areas of Canada and Australia as mines wind down. 100km or 150km between gas stations is pretty standard in regional Australia. However, it seems as though the really remote ones are kept going on local govt/indigenous community subsidies. Not sure about the US – perhaps Route 66 had a few gas station closures too. That said, the population figures are not at all comparable (and calling some of outback Australia`s roads highways would be very charitable).

    • It’s quite a challenge to tell if the Chugoku is more expensive than the Sanyo, because the search engines automatically assume that no-one in their right mind would drive the whole of the Chugoku from Osaka to Shimonoseki and generate routes that send you at some points down on to the Sanyo… But, yes, it’s about Y10,000, versus Y8,500 on the Sanyo. I drove it at weekends both ways and paid the flat-rate Y1,000 (x2, as I stopped off midway).

      I almost added a sentence along these lines: “But you have to pinch yourself and remember this is not an outback road to Alice Springs or a camel track across the Sahara.” There are almost as many people between Osaka and Fukuoka as there are on the Australian continent…

    • “Not sure about the US – perhaps Route 66 had a few gas station closures too.”

      I think I’ve been on sections of it in Arizona as a kid, but Route 66 is really just a local highway anymore having been superseded by freeways decades ago. It’s definitely fallen into the category of a “blue highway.” There are thousands of miles of highway and freeway between the Rockies and the Mississippi where “Last services for X miles” signs are common. Particularly in the northern plains.

  4. +400 km of empty road is a cyclist’s paradise!

    • Surely it is. You’ll just have to wait awhile (half a century should do it) before they let pedal pushers on the Chugoku.

  5. Thankyou for another eluminating update. I find your blog very interesting.

  6. If it’s as empty as you say, then I suppose the Chugoku Expressway will be one of the routes that the DPJ will eliminate tolls on once they finish their little ‘experiment.’ I’m sure traffic would increase if it was a toll-free highway, especially once the San’in Expressway is finished.

    • You might think so, but no part of it is in the current experiment, so unless all the highways go toll-free, I have my doubts.

  7. Is this a toll highway? I assume it is because I am not aware of any non-toll expressways in Japan. It certainly seems the Chugoku’s destiny is set due to depopulation and the newer expressways but if this is still a toll highway, why wouldn’t they reduce or eliminate the toll to increase traffic on the Chugoku?

  8. My guess about gas stations in the U.S. – for every three that open one closes. Of course some roads are less traveled as people migrate to the large urban areas looking for employment.

  9. Miles of deserted pavement — not only expressways, but also the countless twisty local roads that snake needlessly up and over scenic mountains — are what make Japan a paradise for motorcyclists. So long as there are still enough gas stands open here and there for fueling up, the emptier the roads are, the better the riding gets.

  10. Great blog read.
    I live in Western Canada and 100 km between roadside gas stations is fairly common. Especially late at night.
    I was wondering myself about the toll fees. It seems like a diminishing returns sort of thing. Obviously high tolls will force more cars and trucks onto the side roads. Yet I presume that each exit must have toll booths with 24 hour staff. Surely money spent on that staffing might be better spent on maintenance and upkeep. There are visible pavement cracks in each of your photos on this page. I can’t image that it will take too many winters to turn some of those sections into vast potholes.
    (Though of course, if they just raised tolls even higher then the low traffic volume should preserve the pavement forever).

    • Oh. I wanted towrite something about the downside of modern more fuel-efficient cars. The cars of my early driving years would make about 400 km on a tank of gas only at low speed with a trailing wind. My current Hyundai can cruise all afternoon at 110 kph; almost 700 km if I am lucky. These modern cars have little need of refuelling outside the bigger cities. Therefore less need for rural gas stations.
