Hiking in Oze National Park

Hiking in Oze National Park

The vast wild space of the national park covers vast areas of Fukushima, Gunma, Niigata, and Tochigi Prefectures. Boasting a diverse environment of marshlands, lakes and mountains where plants and wildlife can flourish. A wooden boardwalk allows you to walk through the nature without disturbing and small wildlife who may be hiding in the tall grass or harming the fragile marshlands.

When to visit?

Visitors primarily come from mid-May to late-October, outside of these months, the area is blanketed with deep snow.

In spring and summer various wild flowers grow in the fields and the marsh, creating a lovely atmosphere of vibrant greens and bright colored flowers. In Autumn, the grass turns a golden brown and autumn flowers bloom, my favorite was a deep purple flower. Some more adventurous explorers have visited in the winter months, however I would recommend against doing so unless you have the proper skills, permit, and guide. Facilities are also closed during the winter months.

Beginner friendly:

Hike to Lake Ozenuma (6.4 km roundtrip)

The short hike to Lake Ozenuma take you’re through a deep forest where shadows may keep pathches of snow and ice frozen even in the late spring and early summer months. The cool shade of the trees is refreshing but may be cold, so I would suggest bringing warmer layers.

Once you reach the first marsh area you will be greeted with incredible views of Mt. Hiuchi (Hiuchigatake) in the distance, and as you walk you will start to see Lake Ozenuma as well. The lakeside views of the water are incredible as well as the various plants that are growing along the water. Keep an eye out for animals as you may catch a glimpse of them in and around the water.

Overlooking Lake Ozenuma, you’ll find the Oze National park visitors center, as well as a shop, restaurant, and guesthouses that operate here. Snacks, souvenirs, and even alcoholic beverages can be purchased here, so while you will definitely want to pack snacks, you should be able to buy more here!

It’s a very relaxing place to spend time so I would suggest planning to have time to spend here for lunch and relaxing. After which you can choose to head back, or continue hiking if you are able to spend a night or so in one of the lodges or mountain huts in the park.

Stay the night!

If you want to continue hiking past Lake Ozenuma, then I recommend booking a stay at one of the lodges or mountain huts. When I visited during the Autumn hiking season, I stayed a night at the Chozo Hut (built in 1915!) and had a marvelous time.

The weather was much colder, but a wood burning stove kept us warm, and there were a variety of books and games to keep us entertained.

This Lodge is run by the descendants of one of the first pioneers who ventured into the wilderness that is today known as Oze National Park. That pioneer, Chozo Hirano, fell in love with the incredible natural landscape and set up a small cabin along the side of Lake Ozenuma.

A bit of history of conservation

More than 130 years ago Chozo Hirano at 19 years old he discovered the beauty of the area. In 1890, at 20 years old, he built a small hut near the water where he would spend a lot of time basking in the natural wonder of the area. This hut was later moved and rebuilt a bit bigger in 1915, creating the modern day Chozo Hut that could accommodate more visitors, allowing Chozo to share his love of the area with more nature enthusiasts who would come to appreciate the incredible nature.

Some years later a project to build a dam in the park premises was proposed. This would spoil large parts of the environment that wildlife depended on for survival. Chozo and his fellow nature enthusiast fought against this proposal.

Thanks to the efforts of Chozo Hirano and the other conservationists, the Oze Conservation Association was formed in 1949. Through their efforts, the natural area was preserved and Oze National Park was created!

In the 1950s the placement of wooden boardwalks began in an effort to prevent visitors from harming the soft marshland areas.

Today the diverse wildlife and plant life flourish in the park as much of the national park has been left un touched by people.

Geological History

The geological history of Oze National park can be traced back 2 million years, when the Oze area was just a plateau. Over time, the plateau became mountainous, the highest peak Mt. Hiuchi (Hiuchigatake) is located in the portion of the park that lies within the Fukushima Prefectural border and can be seen from Lake Ozenuma.

Mt. Hiuchi (Hiuchigatake) is not only the highest peak in the park today (at 2,356m), but it is also the most recent to erupt. Recent being a relative term, since we are talking about an eruption that took place some 350,000 years ago or so. Lava flow interrupted some rivers in the area which led to the formation of Lake Ozenuma!

The flow of rivers in the area continued to change over time which created the unique wetland landscape that is one of the largest of its kind in Japan.

Oze Marshland

A layer of peat that is as thick as 5 meters in some places is thought to have formed over the course of 6000 to 8000 years!

What is peat you may ask? It is essentially a mix of soil and an accumulation of plant life that never fully decomposed due to cold temperatures and humidity. If you enjoy whiskey that has a slightly smoky flavor, then you may be familiar with peat and some of its many uses. The peat as well as all other natural features of Oze National Park are protected, so don’t try to take any home with you!

To avoid damaging the environment, be sure to stay on the wooden boardwalk trails.

    Wearing Kimono in Ouchijuku

    On a clear autumn morning, I stepped out in a bright purple kimono, tabi socks and wooden sandals, my hair up in a pink flower kanzashi hair pin and a cloth purse in hand. The sky looked sparkling blue in the quiet town of Ouchijuku, located between the mountains of the Japanese countryside. What happened next was unforgettable. The Start of my Ouchijuku Kimono Experience “Kimono is for everyone”, the kimono specialist, a middle-aged woman with a thick Aizu accent, reassured me. Few garments are as universal and inclusive as kimono. Sunlight was timidly spilling into the room through the translucent paper windows when my kimono experience began. We were in a wide room parched with tatami floors, warming up close to a heater. First, using a kanzashi hair pin, she quickly and effortlessly arranged my hair. Next, it was time for me to pick my kimono. Kimono means ‘a thing to wear’ in Japanese, and is a timeless item of clothing adaptable to different body types and designed to last for generations. I opted for a bright purple kimono that matched the fuchsia flowers on my hair. I put on white tabi socks and a black cloth bag with embroidered cherry blossoms. As a cat lover, I was delighted when the staff suggested I wear a white obi with pictures of cats. That same kimono must’ve been worn by many before me. Kimono has no sizes and is a timeless piece. In the face of ultra-fast fashion (and its subsequent toll in the environment), this sustainable and inclusive garment has stood the test of time and remains as relevant as ever. Welcoming as it is, kimono does have its intricacies—for one, you need someone to fit you into it. The kimono specialist will answer all the questions you may have, as well as teach you a few local secrets to make your visit even more memorable. Booking a kimono experience brings you closer to Japanese culture in more ways than one. Stepping into the Past: Picture-perfect Ouchijuku Ouchijuku is an old town preserved to look exactly the way it did 300 years ago. Rows of thatched roof handcraft shops and restaurants, no cars nor electricity poles on the streets and little streams shushing along the road, it’s a postcard-like gem hidden between the mountains of the Aizu region. Either people in Ouchijuku are extremely welcoming or the kimono was truly special, because visitors and locals alike would go out of their way to compliment me or even ask to take my picture. Elderly ladies tending for the shops would greet me with a broad smile and a friendly “kawaii, desune!” (‘You look very cute!’). It was a lovely way to connect with everyone—the flowery kimono helped start many warm conversations. A Taste of Aizu Samurai’s Soul Foods It finally was time to sit down for a meal. If you visit Ouchijuku, make sure to build up some hunger and indulge in local specialties. This is what I ordered and would recommend you try! Takatosoba (高遠そば) is Ouchijuku’s signature dish: buckwheat noodles served with grated radish soup and eaten with a green onion. The radish used in this dish is called ‘azagi daikon’ and grows naturally in the Aizu mountains. It smells as tangy as it tastes. What makes this dish unique is that you eat it with a green onion instead of chopsticks or a spoon. You’re welcome to bite into the green onion, too, once you’re done.     Nishin no sanshosuke (にしんの山椒漬)is pickled herring with sansho (Japanese pepper). The herring was buttery soft and marinated in soy sauce. The Japanese pepper leaves on top had a strong but refreshing taste. Kozuyu (こづゆ) is a staple dish of the region, said to have been a favorite of the Aizu samurai. It’s made up of a hearty scallop broth, fish cakes, carrots, konjac noodles and gluten croutons. This delicately presented dish is the perfect way to warm-up during cold days. Sweet soybean flour-flavored tochimochi (栃もち・きな粉) was my personal favorite. These two chewy, warm and powdery mochi were arguably the best I’ve had in over four years that I’ve been living in Japan. Each bite had just the right amount of sweet, with the sweet soy flour kinako powder sprinkled on top leaving behind an almond-like aftertaste.   The Most Instagrammable View of Ouchijuku The best view of Ouchijuku can be found after a short walk through the main street towards the shrine. Climb up the stone stairs and you’ll find yourself in front of a famous photo spot overseeing the traditional minka houses, mountains stretching out in the background. In spite of its striking beauty, this town remains quiet and rarely sees crowds, making it perfect for visitors who enjoy taking their time to explore places off the beaten path. After looking through the pictures of that day, I noticed that the prints of kimono look even more vivid against the backdrop of Ouchijuku’s earthy hues. Strolling through such a well-preserved historical site in a kimono was a one-in-a-lifetime experience. If you’d like to wear a kimono in Ouchijuku, read more about the Ouchijuku Edo Time Slip and Kimono Tour, which includes a two-hour stroll in a kimono, matcha and sweets at a traditional tea house, and entry to the townscape exhibition hall where you can learn more about the way of life way back then at Ouchijuku.

    Guide to Visiting the Famous Tadami River Bridge Viewpoint

    We're currently working on updating this entry, as some of the information may not be up to date, . We apologize for the inconvenience. (2022-11-16)   I am often asked about how to reach the No. 1 Tadami River Bridge Viewpoint (also known as Daiichi Tadami River Bridge Viewpoint) which has become the focus of spotlights across the world. Taking a look at the beautiful photographs that can be taken there, it is easy to understand why people all around the world have fallen for this picturesque area. When you begin to Google it, getting to the viewpoint can seem quite daunting, so I decided to make a guide on how & when to visit the Tadami River Bridge. VISITING VIA PUBLIC TRANSPORT The Tadami River Bridge Viewpoint is a few minutes’ walk from Ozekaido Mishima-juku – a roadside station (known as ‘Michi-no-Eki’ in Japanese), which sells omiyage (souvenirs), snacks, and light meals. See here for a map of Mishima-juku. Mishima-juku opens daily at 8:00am.   1.) GET TO AIZU-MIYASHITA STATION To reach Mishima-juku, travel to Aizu-Miyashita Station, on the JR Tadami Line from Aizu-Wakamatsu Station to Aizu-Miyashita Station. See here for information on getting to Aizu-Wakamatsu Station from Tokyo, Sendai etc.   2.) TAKE THE BUS FROM AIZU-MIYASHITA STATION TO MISHIMA-JUKU A commuter bus leaves Aizu Miyashita Station every day at 8:10 am, and arrives at Mishima-juku approximately 5 minutes later. No booking is necessary for this bus. Please pay the driver upon exiting the bus. You can also walk to Mishima-juku from Aizu-Miyashita Station (approximately a 40-minute walk) but this route involves walking along roads without footpaths which can be dangerous so I highly recommend you take the bus or rent a car.   3.) WALK TO THE VIEWPOINTS & SNAP AWAY! The various viewpoints are all a short walk uphill from Mishima-juku. If facing Mishima-juku from the road, turn to the right and walk towards the tunnel. Before you get to the tunnel, take the foot path on the left hand side (there should be a sign with an arrow on it to guide you up the foot path.   4.) TAKE THE RESERVATION-ONLY BUS BACK FROM MISHIMA-JUKU There are 2 buses a day that leave Mishima-juku, heading for Aizu Miyashita Staiton.These buses must be reserved, and there are strict time deadlines for the reservations (see below). To catch the bus that leaves at 10:20, you must reserve your spot by 9:00. To catch the bus that leaves at 13:20, you must reserve your spot by 12:00. You can make a reservation inside the Mishima-juku. Ask them for the bus reservation sheet  (In Japanese: Demando basu yoyaku moshikomisho onegaishimasu デマンドバス予約申込書をお願いします) and fill it in. Click here to see an application from previous years to give you an idea of what the form might look like. (Please note, it might have been updated) Make sure to arrive at the bus stop 5 minutes before the departure time. Hand this form in when you get on the bus. When returning to Aizu-Miyashita by bus, pay the driver upon exiting the bus. This bus takes between 5 to 10 minutes. Please be aware that neither the commuter bus to Mishima-juku, nor the reservation-only bus that leaves Mishima-juku run on Sundays or National Holidays. For more information on catching these buses, take a look at this information provided by Oku-Aizu   WHEN TO SNAP YOUR PHOTOS The most famous pictures taken at the Tadami River Bridge Viewpoint are those taken when the train carriage passes over the bridge. The train that you can see from afar is passing between Aizu Nishikata Station and Aizu Hibara Station. Below I’ve listed the times that you can view the trains passing over the Tadami Bridge (Correct as of April 2020). AIZU NISHIKATA STATION TO AIZU HIBARA STATION (Passing from left to right as seen from the viewpoint) 06:04 - 06:07 07:39 - 07:42 09:18 - 09:21 13:03 - 13:06 16:02 - 16:05 AIZU HIBARA STATION TO AIZU NISHIKATA STATION (Passing from right to left) 07:21  - 07:25 08:59 – 09:03 14:21 – 14:24 18:10 – 18:13 Please note: I haven’t listed trains that leave later than 19:00, as you wouldn’t get a good view of the train regardless of the season. Also, there is a separate Winter Timetable so please check an up-to-date timetable for the JR Tadami Line in winter. As you can tell from the information above, the commuter bus arrives nearby the viewpoint at 8:15. However, passengers on the commuter bus cannot reach the viewpoint in time to see a number of the trains passing over the tracks. For those who want to see these earlier trains (especially the extremely early 6:04 train which looks absolutely spectacular in the early morning summer mist), I recommend staying overnight in Miyashita Onsen town. STAYING IN MIYASHITA ONSEN For those who would like to stay overnight in Miyashita in order to see the first train cross over the Tadami Bridge, take a look at the accommodation information listed below: (These ryokan and guesthouses have some experience with guests from abroad) Miyashita Onsen Eikokan Miyashita Onsen Furusato-so Oku-Aizu Nonbirikan (website here) Guesthouse Sokokashiko  (website here) See Oku-Aizu’s website for more information about local ryokan.   ABOUT THE JR TADAMI LINE The JR Tadami Line crosses approximately 135 km of beautiful Japanese countryside, passing through 36 stations along the way. See here for more information about the stops and timetable. Due to damage caused by heavy rains in 2011, service was suspended for certain parts of Tadami Line, but on October 1, 2022, the entire line resumed operations for the first time in almost 11 years. Holders of the JR Rail Pass can ride on the Tadami Line! See below for an English-language tourist map I made of Mishima Town (Miyashita Onsen & Hayato Onsen).

    Tadami Line: 5 Sights You Shouldn't Miss

    The Tadami Line is an incredibly scenic railway that runs across Aizu. Connecting the bustling samurai city of Aizu-Wakamatsu with the serene, gorgeous countryside of Oku-Aizu, this route is definitely one to try out if you want a chance to see rural Japan at its best.
