First, a disclaimer. The information that I’ve compiled here includes tips that I believe will be most helpful. But keep in mind that this guide is meant to serve as a reference, based on my own personal experience. Conditions on the trail are constantly in flux. It’s essential to research the latest information before setting out and to adapt as conditions on the trail change.

Another thing to keep in mind: On long trails, there is no such thing as the right way.

By definition, thru-hiking involves walking the entire trail in a single journey. For a trail longer than 1,000 kilometers (600 miles) like the Michinoku Coastal Trail, you’re spending nights in tents, guesthouses, inns, or other accommodations along the way.

Technically, section hiking involves only walking a portion of a long trail. It might be a day trip. It might last a week or even longer. The appeal lies in sticking to areas that interest you and enjoying the trail on your own terms, at your own pace.

A section thru-hike is, as the term suggests, a mix of the two: completing the entire trail by hiking it in sections at different times.

Anyone who wants to complete a long trail but can’t take enough time off to walk it in one go. This is a common tactic for many hikers on the Michinoku Coastal Trail and other long-distance nature.

This guidebook is for anyone who’s considering a thru-hike of the Michinoku Coastal Trail.

Most thru-hikers spend one to two months on the trail. But every hiker’s fitness level, walking style and speed differs. To complete the 1,059-kilometer (658-mile) trail in a month, you would have to average about 34 kilometers (21 miles) per day, without any days off; the daily average falls to 17 kilometers (10.5 miles) per day if plan on finishing in two months.

Since much of the Michinoku Coastal Trail is relatively flat and passes through towns, it’s possible to cover more ground than if you were hiking in the mountains. But there are also some uphill sections and mountain passes, so you need to plan accordingly.

It took me 33 days, including one rest day, to thru-hike the trail. But time and speed shouldn’t matter as much as the experience itself: How fulfilling is it? You would’t want to walk the trail as if it were a task on a checklist.

A friend told me that he repeatedly left the trail to visit places that sparked his interest. His thru-hike ended up taking nearly three months. It reminded me of a monument at the starting point of the Kyushu Nature Trail that quotes Benton MacKaye, the visionary behind the Appalachian Trail:

“One purpose of a nature trail is to improve physical fitness; another is to foster an appreciation of nature. If, in the future, competitions are ever held on nature trails for the sake of physical achievement, it would be most unfortunate. And if that day comes, I would unhesitatingly give the prize to the person who finished last.”

The message is clear: Hike your own hike!

The Michinoku Coastal Trail connects Kabushima in Hachinohe, Aomori prefecture, with Matsukawaura in Soma, Fukushima prefecture, but unlike some trails, there is no officially designated place to start or finish. Hikers who head north from Soma are known as NOBOs (northbounders); those who go south from Hachinohe are SOBOs (southbounders).

Spring is when many hikers head north from Soma. This strategy gives hikers a better shot at encountering warmer weather up north, where chilly temperatures last through early spring.

Southbounders tend to set off from Hachinohe in autumn. This allows them to avoid the lingering heat of early autumn and the cold that’s soon to arrive.

Neither direction is inherently better.

Terrain and scenery might influence your decision to walk northbound or southbound. The southern portion of the trail passes through more urban areas, while the northern sections get progressively wilder, more natural. Some may prefer the wilderness landscape first; others may want to save it for later.

Less-experienced hikers might want to start from Soma and head north. The terrain near Soma is more level and forgiving and you pass through plenty of cities and towns, so it’s easier to refuel or, if needed, to exit and make your way home.

Spring and autumn generally offer the most comfortable hiking conditions.

That said, one of the strengths of the Michinoku Coastal Trail is that it can be enjoyed throughout the year.

These seasons offer a pleasant balance, with temperatures that are neither too hot nor too cold. Autumn, however, coincides with Japan’s typhoon season, so hikers should monitor weather conditions carefully.

In summer, high temperatures bring a higher risk of heat exhaustion. Think intense humidity and heat radiating from the pavement. You’ll sweat profusely and need to rehydrate with a lot of water. Insects and leeches are also more active.

On the other hand, the trail passes beaches along the Pacific coast, so you’ll be able to cool off with a quick dip or swim.

And a word of warning: You’ll come across vending machines and convenience stores. Don’t overdose on the ice-cold Cokes!

Talk about Tohoku’s winters and many in Japan will imagine deep snow and an icy chill that would make hiking unpleasant. Actually, though, the climate along the Pacific coastline is not quite so extreme. All you need is to proper prepare and pack clothing and gear for snow in the mountains and icy surfaces elsewhere. There are other benefits: the clear views, thanks to the visibility in dry weather, and the feeling of easing post-hike muscle aches in a hot spring, for instance. Check out the Michinoku Trail Club blog, hiking maps and tourist information listings.

On a hike lasting over a month, detailed day-by-day planning can be challenging. A more realistic approach is to plan one to three days at a time while paying attention to three essentials:

ー Food resupply
ー Water sources
ー Overnight accommodations

The Michinoku Trail Club’s online catalog of maps and data provides distances between landmarks, elevation information, nearby train stations, accommodations, toilets, shops and water sources.

You can replenish food supplies along the way at:

• Supermarkets
• Convenience stores
• Local grocery and general stores

You don’t need to carry a lot of food. That’s because you’re likely to come across places where you can replenish your food supplies every one to three days.

The longest stretch without a reliable place to stock up on food is on the Omoe Peninsula in central Iwate prefecture, where you may have to go 50 kilometers (31 miles) before you can make a pitstop.

Supermarkets and convenience stores are a reliable option. Not always so with local mom-and-pop shops, which might have fewer items, shorter business hours and odd days off. It’s best to call ahead of time or load up on extra food ー instant noodles, ready-to-eat rice, for instance ー from big stores. That said, small shops are a valuable opportunities to speak with local residents. I made an effort to support the local communities along the trail by purchasing food and trying regional specialties that I could only find in these places.

• Campsites
• Inns, guesthouses and business hotels
• Places where permission has been granted by residents or landowners

The Michinoku Coastal Trail has no designated overnight sites, so hikers need to plan their own accommodations. Check out the Michinoku Trail Club’s information on Google Maps for camping areas along the route.

The reality is that it’s difficult to only stay at campsites. You’ll also need to stay at guesthouses and other accommodations. I slept at several inns along the route, and was treated well whenever I mentioned that I was hiking the Michinoku Coastal Trail. Fresh local seafood, a comfortable bed and warm hospitality made these some of the most memorable parts of my journey, and I encourage every hiker to look into this option as well as the lodgings offered by some members of the Michinoku Coastal Trail Supporters network.

• Streams and springs
• Tap water
• Vending machines

I recommend carrying a portable water filter. Though I rarely needed to fill up at streams, there were still times when it was a life-saver. Having it gave me an emergency fallback and meant that I didn’t have to carry so much water all the time.

Most of the time, I found facilities that let hikers refill their water bottles in the communities along the Michinoku Coastal Trail that I passed through.

When planning your itinerary, check the Michinoku Trail Club’s Data Book and Supporters information. Another unique feature of hiking in Japan: the abundance of vending machines. You’ll find them even on remote rural roads. They become harder to find, though, as you travel north, so don’t depend on them too much.

I hiked the trail during the relatively warm months of September and October, but I never carried more than about 2 liters (half a gallon) of water at a time or had trouble finding somewhere to fill up. Of course, everyone’s pace and hydration needs differ. Understanding how thirsty you get and how much you need to stay hydrated under different conditions is crucial.

The Michinoku Coastal Trail is mostly paved roads ー roughly 70 percent, in fact ー and trail washouts are rare.

For hikers used to climbing mountains, walking on paved roads might sound unappealing. But the Michinoku Coastal Trail is hardly just an endless stretch of road.

The natural scenery makes for an enjoyable walking along the route, paved or unpaved. As I mentioned, imagining the historical significance of the roads that once connected villages and observing the distinctive qualities of each community is one of the pleasures of the trail.

The unpaved paths are well-maintained and easy to follow. There were no impassable or dangerous sections. I was traveling when vegetation was at its thickest, but I never got lost, thanks to the trail management efforts of organizations and local volunteers.

The few rough sections that I encountered were, I later learned, areas where route changes had recently been made and maintenance work was in progress. The route continues to evolve, with efforts underway to add more natural paths wherever possible.

Note: Although trail conditions are generally excellent, don’t get complacent. Even minor lapses in judgment can lead to serious accidents. No one is inspecting the trail week to week, and typhoons and other natural disasters can alter the state it’s in. Be sure to check the most up-to-date information about closures and detours on the Michinoku Trail Club’s website.

It’s relatively easy to leave the trail thanks to JR and other private railway lines along the Pacific coast.

From north to south, public transportation options include:

JR Hachinohe Line (Hachinohe–Kuji)
Sanriku Railway (Kuji–Sakari)
JR Ofunato Line (Sakari–Kesennuma)
JR Senseki-Tohoku Line and BRT (Ishinomaki–Sendai)
JR Joban Line (Sendai–Soma)

While these lines are not always near the trail, they are extensive, stretching from one end of the trail to the other. There are also local bus services.

There are a few spots that require extra planning due to longer gaps between services and settlements. Notably: The peninsulas, between northern Miyagi and central Iwate prefectures ー Omoe Peninsula, Funakoshi Peninsula, Hakozaki Peninsula, and Ogatsu Peninsula.

Besides places that have been hit by typhoons, heavy rain or other natural disasters, hikers should be aware of the following hazards.

On the border between Hirono and Kuji in northern Iwate is the Takaya River. You will need to wade across it. Water depth and current speed vary depending on the season and a safe crossing can depend on a hiker’s size and experience. If it seems risky, take the detour instead. Avoid the crossing during the spring snowmelt season or after a torrential rainstorm, when the river can become dangerously swollen.

After dark, it’s best to avoid the sections of the trail on busy highways or roads without sidewalks.

Pay attention to the tides. Several sections in northern Iwate run along the shoreline and may be impassable at high tide.

The Japan Meteorological Agency publishes tide tables for locations throughout the region but only in Japanese. I had to change my route a few times due to high tides. Even so, getting drenched by a wave while walking along the beach is one of my favorite trail memories.

Asian black bears inhabit most of the mountainous areas near the trail, and there have been sightings. Hikers should make their presence known using radios, whistles or other noise-makers. Try to avoid traveling at dawn, dusk or nighttime.

I never encountered a bear, but I did come across fresh bear scat several times. Winter hikers should also be vigilant: Bears along the Sanriku coast are thought to skip hibernating during the coldest months.

Encounters with wildlife are part of hiking. Still, steering clear of bears whenever possible is the key to their safety, since encounters can lead the authorities later to hunt down and kill the animal for the sake of other hikers.

Japanese giant hornets are aggressive, and fatalities from hornet stings reportedly outnumber those caused by bears. They’re most active from May through October, which overlaps with the main hiking season. While I was on the trail, one section was temporarily closed because of hornets. (Japanese giant hornets are just one of the 17 types of hornets in Japan.)

Land leeches inhabit areas along the Michinoku Coastal Trail, especially the Oshika Peninsula in Miyagi prefecture and neighboring Kinkasan Island.

Unlike bears or hornets, leeches are rarely life-threatening for hikers. But they can cause prolonged bleeding, itching and swelling.

When I hiked through the area, it was rainy, and despite my having applied generous amounts of repellent, my legs were covered with leeches. I had anticipated the possibility and hurried through the section at a near jog. Even so, the sight of leeches climbing my legs every time I looked down was psychologically draining.

The trail is well-marked with signposts, but don’t rely solely on them. In some areas, there aren’t many signposts, and staying on the route can be challenging.

The Hiking Map Book is the official map series published by the Michinoku Trail Club. The trail is divided into ten sections of roughly 100 kilometers (60 miles) each. The maps include route information, elevation profiles, water sources, toilets, resupply points, restaurants and distances between landmarks.

This B5-sized guide contains more detailed information than in the Hiking Map Books, showing distances between points. It’s invaluable for planning. I primarily used the Hiking Map Books for route-finding while I relied on the Data Book for calculating distances, planning food and water resupplies and figuring out accommodation options.

Official route data is available on Google Maps, and GPX files can be imported into other navigation apps. These resources work best as supplements to the official maps. The Google Maps version also includes information on landmarks and camping locations.

The Michinoku Coastal Trail runs through relatively low-elevation terrain, so hikers generally don’t need to worry about the severe mountain weather of alpine regions. But on a long-distance hike, you should take emergencies into consideration when choosing your gear.

If you plan to hike during the colder autumn or winter seasons, prepare for cold weather. Even though the trail passes near towns and villages, there are still isolated sections where help won’t be close by. Also, don’t expect to buy or replace gear along the trail.

Below you’ll find a list of the gear that I used. Keep in mind that this should only be a reference. Adjust your own gear list for the season, temperature, weather, your hiking style and your tolerance for hot, cold or wet conditions.

【Esbit】Alcohol-burning stove

For long journeys, I usually choose a gas stove. This time, I went with an alcohol stove. The main reason was fuel availability. Towns along the trail are often small, and fuel canisters are not always easy to find. Alcohol fuel, on the other hand, can be purchased at drugstores. Carrying 500 ml (17 fl oz) in a bottle was enough to cover morning coffee and evening meals for more than two weeks without needing to resupply.

People often associate alcohol stoves with ultralight hiking, but this stove is made of brass and weighs about 90 g (3 oz, or 0.2 lbs), so it’s not especially lightweight. Its advantage: flame adjustment, which makes cooking rice and other simple preparations possible.

【Trangia】Mini

This cooking set consists of an 800 ml (27 fl oz) aluminum pot and a simple frying pan that doubles as a lid. I normally use a lightweight titanium pot for instant noodles on long trails but for this trip I planned meals of rice and whatever unique local ingredients that I could find while passing through towns and villages. I grilled produce that I bought at roadside stations (michi-no-eki) and even made rice cooked with wakame seaweed.

【Kontex】MOKU Light Towel

Kontex bills its MOKU as “more than a tenugui (a thin cotton tea towel), less than a towel”. I like how practical and lightweight it is and how quickly it dries. At around 50 g (1.8 oz), it is slightly heavier than a traditional tenugui, with gauze on one side and pile fabric on the other. It has excellent absorbency and is also highly breathable, so it dries quickly. With many bathing facilities near the trail, this towel was ideal.

【Yamatomichi】Active Pullover

I always bring this versatile midlayer on long hikes. I use it as insulation, active wear and a change of clothes. It’s plenty warm when temperatures dip to around 10°C (50°F) and performs well even when wet. The fabric itself absorbs very little water, so I can comfortably wear it even after getting soaked, which is vital in Japan where getting wet is often unavoidable.

Cutting back on the gear you carry is one of the key principles of lightweight hiking. Carrying fewer items reduces the number of decisions you have to make and can reduce stress on a long journey.

【Yamatomichi】Chemical B Pocket T-shirt

I usually wear merino wool base layers. This time, I chose the 100 percent Yamatomichi’s polyester Chemical B Pocket T-shirt.

Even in hot, humid conditions, the shirt performed extremely well: it wicked sweat away instantly, prevented moisture from building up on my skin, minimized contact between the shirt and my skin, and dried quickly. Even when I got wet, the shirt helped to reduce any discomfort I might have felt.

Another major advantage of the Chemical B: odor resistance. Usually, Merino wool works better for me, but the Chemical B shirt performed well. After three or four consecutive days of wear, it had virtually no odor. That’s key when you can’t often stop and do laundry and want to avoid bad body odor while passing through towns and other populated areas on the Michinoku Coastal Trail.
