Yabitsu Pass in the Rain

During my recent trip to Japan, I found myself with a free day in Tokyo. With no time to plan, I decided to head to Yabitsu Pass.

Yabitsu Pass is popular with cyclists, because it’s close to the capital, and yet it traverses a mountain range that is far off the beaten path. You could ride there from central Tokyo, but I decided to take the train for the first leg of the ride. Not only does this save time, but it keeps navigation simple. The way I did it, the ride across Yabitsu Pass has only three or four turns where one could get lost.

An hour’s train ride from the center of Tokyo brings me to Takao at the foot of the mountains. The first thing I do is un-Rinko my bike – remove the carrying bag and assemble it.

Twelve minutes later, I am ready to roll. My ‘Mule’ currently lives in Japan. It’s nice to have a bike waiting for me when I arrive – a bike that can handle anything from a fast group ride to loaded touring.

Heading out of town, I stop at my favorite shrine for a moment of contemplation. As is the Japanese custom, I pray for safety on the road. It reminds me to be careful and not take undue risks as I head out for an adventure.

After riding through suburbs for a while, I enjoy the short, steep climb as I reach Lake Miagase. The lake is formed by a large dam, and I have to climb that elevation all at once, with a gradient that feels like 18%. My Japanese is making only slow progress, but I don’t need to read Kanji to understand what this sign says. Alas, no cute monkeys are visiting the park today.

My effort is rewarded by the view across Lake Miagase. Today the mountains are shrouded in mist. The weather forecast predicted a 20% chance of showers. Usually, Japanese forecasts are very accurate, since they rely on the latest technology. So I hope that the rain I see falling on the lake is just one of those ‘showers.’

From here, the ride is heading into the mountains. I follow the beautiful road that skirts the shore of the lake.

When I reach the rugged valley that leads to Yabitsu Pass, rain starts falling in earnest. It’s not typhoon season, but it doesn’t feel all that different, except the rain is colder. I am glad the ‘Mule’ has generous fenders and a good mudflap. I am getting wet from above, but there isn’t the constant barrage of spray that can chill legs and feet to the bone. I am carrying enough clothes in my handlebar bag to deal with any conditions, as long as I keep moving: wool tights, extra layers and a rain shell. For emergencies, I carry a space blanket. It’s not so much equipment that it’ll slow me down, but it’s enough to be prepared.

The road to Yabitsu Pass is an all-time favorite. The first part is almost level as it goes along the lower reaches of the river. Curve follows after curve, and on a well-handling bike, it’s great fun.

Despite my limited Japanese, I do know the Kanji for rain: 雨. This sign indicates in the third line that if more than 20 mm (0.8″) of rain fall in one hour, the road will close. (The second line says that if 100 mm/4″ fall without a dry spell, it’ll close as well.) In this steep terrain, the danger of mudslides is ever-present. Today, I hoped it won’t come to that!

Just before the real climb to Yabitsu Pass starts, there is a side road that I have been wondering about. I’ve been making good time today, so this seems like good an opportunity to explore it.

The road is closed to motorized traffic with a big gate, but it seems that bikes are allowed. At another fork in the road, I turn left and go up a beautiful valley.

Soon I discover why the road is closed: Rockfalls have made it impassable for cars. No problem on a bike, but wide tires are a plus to avoid pinch-flats.

A big tree has fallen across the road. It’s only a minor obstacle. On wet and slippery ground, it’s not advisable to jump, cyclocross-style, so I take it at a more cautious pace. Click on the arrow to watch the video clip!

I pass a sign for Mt. Tanzawa. A hiking trail scales the steep valley side. I continue on the road, until it ends where another rockfall has completely obliterated the road. Time to turn around and explore the other fork…

The second road is steeper as it climbs the ridge between two valleys. The climbs have a nice rhythm, and I am having a good day. The ‘Mule’ and I get in sync, and the gradient feels much less steep than it probably is.

When I chart the ride on RidewithGPS later, I am surprised how the two sidetrips each climb more than the actual pass! (The steep downhill after the first climb is an artifact of my drawing a straight line on the map – the software doesn’t follow the closed road.)

The road climbs higher and higher in switchback after switchback. It is fun!

The top comes almost unexpected. It’s another trailhead for Mt. Tanzawa. It feels like I’ve climbed the 1567 m (5,141′) mountain from both sides. For a moment, I think of a passhunting adventure. I could hike with my bike to the top, then down the other side. Maybe another day!

The downhill is wet. Very wet! On the steep slope, I drag my front brake continuously, so my rims stays warm enough to evaporate the water. That way, I can brake for the hairpin turns. In conditions like this, powerful brakes are important. If your brakes are marginal in the dry, they cannot cut through the film of water that builds up on the rims when you ride in the rain. No problem with the Mule’s centerpull brakes, though.

When I return to the main road, I am starting to get cold. Fortunately, the gradual uphill invites an all-out effort. That is why it’s so popular with racers. Pushing myself and my bike to their limits, the curving road is great fun. Where sightlines allow it, I don’t slow for the bends, but use the entire road. At other times, I have to brake for the curves, even through the road is heading uphill.

There is no traffic at all. I remember the sign at the bottom of the pass and wonder whether it has rained more than 20 mm in an hour, and the road has been closed. It doesn’t matter – it’s too late to turn around.

As I reach the last, steep kilometer before Yabitsu Pass, I can feel the effort in my legs. I give it everything I have and reach the pass without slowing. Getting here feels like a real achievement today. The pass is deserted on this rainy weekday.

Now all I have to do is coast down the other side to the train station at Hadano. No more photo stops – I need to get down the steepest part of the descent before my body has a chance to get chilled. Then I reach the station. I Rinko my bike and get on the train. I am back in Tokyo for dinner.

If you find yourself in Tokyo looking for a great ride, I recommend Yabitsu Pass. It’s scenic; it sees little traffic (albeit a bit more on sunny weekends); and navigation is easy. The two optional out-and-back side trips add to the challenge if you feel so inclined.

The ride across Yabitsu Pass in numbers:

  • Distance: 66 km (42 miles)
  • Elevation gain: 1300 m (4265 ft)
  • Two extra climbs add about 30 km (19 miles) and 900 m (3000 ft)
  • Link to map on RidewithGPS

    Jan, your Rinko bag must fit in your handlebar bag as I don’t see it elsewhere on your bike. Is there much room left for other travel items?

  2. Franklin Miller says:

    I don’t see a raincover on your saddle. Is it not necessary?

    • I find that as long as I sit on the saddle, it usually stays reasonably dry. I’ve tried raincovers, but I move around on the saddle too much, and they always come off and vanish without a trace.

        Another issue is rain on the saddle once you’re stopped. I don’t worry about a few raindrops on the saddle. For more rain I carry a plastic bag in my in my handlebar bag. When stopping in the rain, I put it on the saddle to protect it. (The bag also doubles as a windshield for my chest underneath the jersey on cold mountain descents.)

      • Absolutely. When I stop, I also cover the saddle with a plastic bag. On this ride, I didn’t stop for more than a few seconds to take photos, and for the photos, I didn’t want to put a bag on the saddle.

    Another great and inspirational report. Thank you for making the effort to write. How does the Ideale saddle tolerate rain? I noticed that you did not use a rain cover.

    Jan, you might know this already but you can manually draw/create routes in RideWithGPS. This is helpful when the app will not or cannot follow a road or trail. You can switch from “follow road” to manual using the controls in the pop out panel on the right.

    As a geographer and someone who works in the mapping industry, RideWithGPS is a brilliant app. Kudos to the developers.

    Jan, the rinkoed package looks pretty big (at least compared to the handlebar bag). I have seen your orther pictures where the package looks smaller. Did you remove the front fork and handlebars in the picture above?
    Also, do the trains in Japan allow removing just the front tires and covering with a bag.

    I ordered the Ostrich SL bag from Compass few days ago and I will be in France for about a month. Looking forward to trying the rinko system.

    • The package is always the same for the cyclotouring bikes with fenders. Just removing the wheels doesn’t make them much smaller! When I travel with a modern bike, I use a bigger bag and just remove the wheels and bars, as the cables don’t disconnect easily, so the handlebars can’t be moved to the rear of the bike as they are in Rinko.

      The baggage regulations of the Japanese railways don’t allow the bigger Rinko packages, but people use them without anybody complaining. What’s not so nice is that they usually stick out in the aisle in the middle of the car, making it hard for the Bento cart to get through on the express trains. If it’s impossible, then half the train just doesn’t get service. I’d rather not do that! On the local trains, there is more room for standing passengers, so during off-peak hours, it’s not a problem.

      • As Jan says, there’s little problem taking a modern bike with the front wheel & bars removed. With my last disc equipped bike removing bars & wheels together with the mudguards & pedals and getting it all into the bag took less than 5 mins—as did unpacking & reassembling the bike. (My record, set when catching the last late night train home, is about 2mins.) I’ve also used without problem a bag where you could just remove the front wheel (& mudguard) and turn the bars. With this and all other bags I usually can just lean or tie the bike upwards at the back of the carriage (incl. on shinkansen) so that the footprint of the bike is really just one wheel wide. I’ve seen people take bikes on regional trains fully assembled & loosely covered by a garbage bag, though this is certainly at the discretion of the conductor, and not something I’d advise. And it’s best not to inconvenience other people.

    Yes, Yabitsu is fun. You can do it north to south (as you did); you can do it south to north (as I generally prefer); you can combine it with Makime pass; you can add little complications for added enjoyment. Next time, consider turning off at the point where your Ride with GPS map says 32.1 km and going around the WSW end of lake Miyagase, crossing the Hayato river and rejoining at 33.7 km on your route. This is undemanding but/so makes an enjoyable break from the other ups and downs. Kimagure (66.0 km on your route) is good for an inexpensive lunch.

    Jan,
    Who is building these lovely gray framesets for you?
    Thanks,
    Derek
