Hike – Oze Marsh 尾瀬ケ原

Oze Marsh and Mt Hiuchigatake

Oze Marsh and Mt Hiuchigatake

Quick Overview

This hike is probably one of the best within a few hours of Tokyo. Oze 尾瀬 is the largest marsh lands in Japan and is very popular during the summer season, but with good reason. It’s famous for skunk cabbages (ugly name, pretty flower) in late May, and autumn colours in late September. It has excellently maintained board walks, and plenty of accommodation within the National Park. A very easy hike, of which the marsh alone could be done as a day trip, but best done overnight so you can see the full beauty and variety of nature Oze 尾瀬 offers.

Distance: 23 km
Duration: 2 days (approx 9 to 10 hours in total)
Difficulty: easy
Season: May to early October
Starting point: Hatomachitoge 鳩待峠
Finishing point: Oshimizu 大清水


A full map of the hike can also be viewed at GPSies

Although this hike is the only major hike in the area, there might not be any maps available at the Oze Visitor Centres so I recommend you buy a map. The Mapple 山と高原地図 series number 14 map is of the region, and is available on Amazon.co.jp. Note, this map is in Japanese, but does include some English and furigana.

The Hike

Day One – Hatomachitoge 鳩待峠 to Miharashi 見晴

Start of the trail

Start of the trail

The bus will terminate in front of a Mountain hut in the car park at Hatomachitoge 鳩待峠. The trail head to Oze marsh 尾瀬ケ原 is signed and easy to find. You will be told to wipe your boots on a mat before walking through a sensor (for counting people) and entering the National Park. The first part of the hike is very easy, downhill on stairs and board walks for about an hour until you reach Yamanohana 山ノ鼻.

Yamanohana 山ノ鼻 has a Visitor Centre which is worth stopping at to pick up a map and up to date information about the weather and facilities in the national park. From here the marsh truly begins. Past the Visitor Centre there is a circular boarded trail on the left, which only takes about 40 minutes to walk if you want to. Or you can start heading further into the marsh by taking the boarded trail on the right.

Following the trail on the right you will see Mt Hiuchigatake 燧ヶ岳 in the distance. The trail will wind through the marshes, over creeks, and through small wooded areas on your way to Miharashi 見晴. Depending on the season, the marshes will be green with flowering white skunk cabbage (late May), yellow alpine lilies (late July), or turning golden with the surrounding mountains covered in an autumn patchwork of colours (late September/early October).

About 40 minutes after leaving Yamanohana 山ノ鼻 there is a branch in the trail, where you can either turn left or continue ahead. Both trails will lead you to the northern end of the marsh, although the trail on the left takes about 2 hours to reach Miharashi 見晴. The map above shows the trail if you continue ahead, and takes 80 minutes to reach Miharashi 見晴. Along both trails you will find benches and some alternative trails, but as long as you keep heading towards Mt Hiuchigatake 燧ヶ岳 you will reach the northern end of the marsh.

Miharashi 見晴 is a good place to stay overnight due to an abundance of mountain huts and fresh water. It is also the starting point of the hike to Lake Oze. All mountain huts offer dinners and breakfast as well as comfortable futons. Some even have baths, although you are unable to use soap. Check out the mountain hut section for details.

Day Two – Miharashi 見晴 to Oshimizu 大清水

Breakfast and check out is early in a mountain hut, so you should have plenty of time to make it to the Oshimizu 大清水 bus stop. From Miharashi 見晴 follow the trail up between the mountain huts. It won’t be very long until you reach a Y intersection. If you have the time and the will, you can head to the peak of Mt Hiuchigatake 燧ヶ岳 on the trail to the left (please look at the Mapple 山と高原地図 series number 14 map for more details), but if you just want to head straight to Lake Oze 尾瀬沼 take the trail on the right. It will take about 2 hours to Lake Oze 尾瀬沼, walking through a forested area and over a low pass.

At Lake Oze 尾瀬沼 you can either walk around the lake in the clockwise or anti-clockwise direction. The clockwise direction, although a longer distance, is easier and has better maintained board walks. The map above shows the clockwise direction trail.

Lake Oze

Lake Oze

From where you started walking alongside the lake, it will take about an hour to reach the Lake Oze Visitor Centre 尾瀬沼ビジターセンター. There are a few trails branching off, but just stick to the lake and follow the signs.

At Lake Oze Visitor Centre 尾瀬沼ビジターセンター there are more mountain huts, toilets and fresh water. There is also a small gift shop and café where you can stop to get a cup of coffee. Once you are finished there, continue walking on the trail between the mountain huts and head towards Sanpeishita 三平下. It will take about 20 minutes to reach, and it’s where you will leave the lake start back to the bus stop.

At Sanpeishita 三平下 head uphill until you reach Sanpei Pass 三平峠, the highest point on the hike. It should only take about 20 minutes, and from there it’s all downhill. In about 50 minutes you’ll reach the hut at Ichinose 一ノ瀬. From here the trail becomes a forestry road, and is a really easy trek downhill for an hour until you reach the huts, shops, toilets and bus stops at Oshimizu 大清水.

To and From

There are a number of different ways to reach Oze during the season.

By Bus
During the hiking season Kanetsu Kotsu 関越校通 runs buses from Shinjuku Station’s New South Exit 新宿駅新南出口 at around 7am and arrive at Tokura 戸倉 and Oshimizu 大清水 around 11am. You can do the hike in reverse from Oshimizu 大清水, or from Tokura 戸倉 you can change bus to Hatomachitoge 鳩待峠. The bus from Shinjuku 新宿 to Tokura 戸倉 or Oshimizu 大清水 costs 3,700 yen one way, and 7,000 yen return. The bus from Tokura 戸倉 to Hatomachitoge 鳩待峠 takes 40 minutes and costs 900 yen. The return bus leaves Oshimizu 大清水 for Shinjuku 新宿 about 3pm. See the Kanetsu Kotsu 関越校通 homepage (Japanese) for more information.

By Overnight Bus
Kanetsu Kotsu 関越校通 also runs the above buses overnight. They leave Shinjuku 新宿 around 10pm and arrive at Tokura 戸倉 or Oshimizu 大清水 around 3:30am. Note, the buses from Tokura 戸倉 to Hatomachitoge 鳩待峠 start running approximately at 4:40am. Costs are the same. See the Kanetsu Kotsu 関越校通 homepage (Japanese) for more information.

By Train and Bus
As always, the following routes are just recommendations. Please use Hyperdia or Jorudan’s Train Route Finder to find the most suitable route for you!

From Tokyo 東京 you can take the Shinkansen to Takasaki 高崎, and then change to the Joetsu Line 上越線 local train to Numata 沼田. By Shinkansen this takes just over an hour and a half, and 5,430 yen. You can also catch the regular train from Ueno 上野 on the Takasaki line 高崎線 to Takasaki 高崎, and change to the Joetsu Line 上越線 as described above. Using the regular train takes about 2 hours and a half and costs 2,520 yen.

From Numata Station 沼田駅 you have to catch a Kanetsu Kotsu 関越校通 bus to Tokura 戸倉, which takes about an hour and a half and costs 2,100 yen. From Tokura 戸倉 you then catch the same bus mentioned above to Hatomachitoge 鳩待峠. This leg takes 40 minutes and costs 900 yen. On the return from Oshimizu 大清水 you can catch the bus direct to Numata Station 沼田駅, with no need to change at Tokura 戸倉. The return leg takes an hour and 40 minutes and costs 2,200 yen.

Bus timetables are a little tricky to read, but here is the timetable for Numata 沼田 to Tokura 戸倉/Oshimizu 大清水, for Oshimizu 大清水 to Numata 沼田, and Tokura 戸倉 to Hatomachitoge 鳩待峠 (all in Japanese). Please make sure you can reach your bus stop in time to catch a bus home. If you are in doubt the Visitor Centres have the most up-to-date information and can help you with your planning.

By Overnight Train
Tobu Railways 東武鉄道 has an overnight train that runs from Asakusa 浅草 to Aizu Kougen Ozeguchi Station 会津高原尾瀬口駅 at least once a week during the season. The train leaves Asakusa 浅草 at 11:55PM and arrives at Aizu Kougen Ozeguchi Station 会津高原尾瀬口駅 at 3:18AM. From Aizu Kougen Ozeguchi Station 会津高原尾瀬口駅 you catch an Aizu bus 会津バス at 4:20AM and arrive at Numayamatoge 沼山峠 at 6:10AM. This hike will use a different trail, heading south to the Oze Lake Visitor Center 尾瀬沼ビジターセンター from Numayamatoge 沼山峠. Please look at the Mapple 山と高原地図 series number 14 map for the trail. The cost of the overnight train starts at 9,200 yen return, but there are a few options, like catching the return bus from either Oshimizu 大清水 or Hatomachitoge 鳩待峠 instead. The Tobu Railways 東武鉄道 homepage has more details (in Japanese).

Great information, thanks!
I never managed to go to Oze despite I love hiking, too.
When did you go there? And was it crowded at that time (my biggest fear).

27 01 2011

Thanks for commenting!
Oze is really beautiful and if you have the chance to go you should take it. I went right before the end of the season on a weekday and it was very quite. I imagine that during the summer it’s pretty busy always, but weekdays seem to be a good idea if you want to avoid the larger crowds!

Finally some real info on how to get from Tokyo to Numayamatoge! The night train from Asakusa sounds interesting. The Hiking in Japan website says there is a bus direct from Shinjuku to Numayamatoge, but I think that’s a myth.

23 06 2011

Thanks for you comment! I think you are right about the bus from Shinjuku to Numayamatoge being a myth, I couldn’t find any info on it myself. Let me know if you use the Tobu train, I was intending to try it this year, but can’t now that I’ve left Japan.

Thank you so much for your kind comment! It’s particularly nice to hear from a Japanese person that the information I’ve provided is good – My Japanese is not that good, so I worry if my translations are accurate! Thanks again!

Thank you for the information, yamaonna. I used your guide to trek through Oze park last weekend. The colors were fantastic! I’m definitely doing this again next year.

A complete information. Really help me with my coming Oze hike plan. Seem to be the hike on the second day(6hr) is longer compare to the first day (3hr). I gonna hike with a few novice friend where I am worried that they could not make it to be at the bus station before 3pm on the second using your hiking route. If hiking using the reverse route Oshimizu to Hatomachitoge will it be easy as well with the downhill hike?. Thank you in advance

Your website and informations are really great, well done! I have a question however. The GPS Data that you uploaded, does the root match the pictures your uploaded on Flikr?

Thank you very much for all the useful information !
I’m going to Oze next week, taking the overnight bus from Shinjuku to Oshimizu. Then i hope to do the circuit to Hatomachitoge via Hiuchigatake in a day. Being the end of the season, i’ll surely stay a night in a hut near the Hatomachitoge trail head and go forth by train the next morning.
So long as the weather is nice, i hope i’ll enjoy the walk 🙂
