The Banetsu Railway Lines – Crossing Honshu Through Mountains, Forests, Rivers & Rice Paddies
Japan is a country with a vast rail network that crisscrosses the interior and follows much of the coastline, offering travelers access to stunning scenery and fascinating local areas.
The two Banetsu lines — the Banetsu East Line (磐越東線), which runs between Iwaki and Koriyama in Fukushima Prefecture, and the Banetsu West Line (磐越西線), which runs between Koriyama and Niitsu in Niigata City, Niigata Prefecture — connect the Pacific Ocean side of Japan with the Sea of Japan side.
Together, these lines span a total of 261.2 kilometers, passing through diverse landscapes that represent rural Japan at its finest: lush rice paddies, towering mountains, meandering rivers, dense forests, and charming towns and villages. The cities at each end — Iwaki, Koriyama, and Niigata — are also sizable urban centers, particularly Koriyama and Niigata.
Both lines are well worth exploring, but the Banetsu West Line is considered one of the most scenic rail journeys in all of Japan!
Exploring the Banetsu Lines: From Iwaki to Niitsu via Some of Japan’s Most Scenic Rail
The Banetsu East Line runs between Iwaki and Koriyama, while the Banetsu West Line continues from Koriyama to Niitsu.
Many visitors may be familiar with this route as a way to reach Aizu-Wakamatsu, but it’s the stretch west of Aizu-Wakamatsu that offers some of the most scenic railway views in Japan — passing through picturesque countryside, rivers, forests, and mountain landscapes.

The name “Banetsu” is derived from the kanji of the two furthest regions that the railway lines connect:
• “Ban” (磐): This character comes from “Iwaki” (磐城), located at the eastern end of the Banetsu East Line. The kanji 磐 can be read as “Ban.”
• “Etsu” (越): This refers to “Echigo” (越後), the historical name for what is now Niigata Prefecture. Much of the Banetsu West Line passes through this region. The kanji 越 can be read as “Ets
Put together, these two kanji — 磐越 — are read as “Banetsu.”
This naming convention is quite common in Japan for railway lines and major roads. So while “Banetsu” may not appear to describe the areas it serves in English, it makes perfect sense in Japanese — just with a change in the reading of the kanji!
The Banetsu East Line has the nickname “Yuuyuu Abukuma Line”, which roughly translates to “Leisurely Abukuma Line”, reflecting the relaxing train ride through the Abukuma region.
From the moment your journey begins, even if you’re not already a fan of rail travel, you’ll soon begin to understand what makes it so special to rail fans and train enthusiasts alike.
It’s a feeling you’ll never experience on a shinkansen or a packed commuter train in Tokyo or Osaka — this is slow travel at its best, through the heart of rural Japan.
Places to Visit Along the Banetsu East Line
- Miharu Station (三春駅) – Miharu Town; A popular area during the Sakura season, particularly for its 1,000 year old weeping Sakura Tree. More Information https://www.japan.travel/en/spot/1747/
- Kanmata Station (神俣駅) – closest station to the Abukuma Cave. The limestone cave is famous for its stalactites and underground scenery. During the summer there is also lavender fields near the cave. The cave is about 30 minutes by bus and walk from the station. More information https://abukumado.com/en/
- Ononiimachi Station (小野新町駅) -Ononiimachi is a small historic rural town. It has a culutral museum (https://japantravel.navitime.com/en/area/jp/spot/02301-t10687/)
- Iwaki (いわき駅) – The city of Iwaki is on the Pacific Ocean coast, although the station is not so close to the coast. There are a number of places that are worth visiting (it should be noted that these are not close to the station or the city centre. (Iwaki tourist information https://www.japan-guide.com/e/e7775.html )
- Iwaki City Coal & Fossil Museum (https://www.japan-guide.com/e/e7779.html nearest Station Yumoto)
- Shiramizu Amidado Temple (https://fukushima.travel/destination/shiramizu-amidado-temple/147)
- Spa Resort Hawaiians (https://www.hawaiians.co.jp/english/)
- Aquamarine Fukushima (https://www.aquamarine.or.jp)
Koriyama (郡山)
Koriyama Station is where the Banetsu East & West Lines meet. It is also the junction with the Tohoku Main Line and where trains on the Suigun Line start and end their journeys.
For rail enthusiasts you will probably notice that the platforms at Koriyama are very long, particularly as most conventional trains serving the station are 1, 2 or 4 cars long. Before the shinkansen Koriyama was an important station with many long distance Blue Trains and sleeper trains operating between Hokkaido / Tohoku and Tokyo would stop. Today most distant travellers arriver at the station by shinkansen.
Koriyama is an important city in Fukushima Pref and a good place for shopping eating and drinking. We would suggest, for those who are doing both the Banetsu routes that this is a good place to stay overnight. (tourist information https://www.kanko-koriyama.gr.jp/kankoenglish/index.html)
Banetsu West Line “The Railway of Forests, Water, and Romance. 森と水とロマンの鉄道”
The Banetsu West Line is more familiar to tourists, especially the section between Koriyama and Aizu Wakamatsu.
However, the most scenic part of the line lies between Aizu Wakamatsu and Niitsu. This stretch showcases the natural beauty of the region and lives up to the line’s poetic nickname:
“The Railway of Forests, Water, and Romance.”
Here, romance refers not to love stories, but to the peaceful, picturesque landscapes the train winds through — forests, rivers, and the charm of rural Japan.
This line is one of TSJR’s Top Scenic Lines in Japan! In fact this area is rich in TSJR’s Top Scenic lines, with not only the two Banetsu lines, but also the Tadami Line, the Aizu Tetsudo Line & the Joetsu Line (Explore Rural Japan by Train – Gunma, Niigata & Fukushima…)
Many railway lines in Japan, particularly those that traverse the country, follow the paths of Japan’s great rivers. The Banetsu West Line closely parallels the Agano River, also known in some areas as the Aga River.
The river originates from Mount Arakai, located on the border between Fukushima and Tochigi Prefectures, and flows through Fukushima and Niigata, eventually emptying into the Sea of Japan. Historically, it has served as a vital transportation route for centuries and is also celebrated for its scenic beauty. During the Showa Period, it was selected as one of the “100 Landscapes of Japan.”
For those looking to enjoy the river up close, boat rides are available at various locations along its course.
SL Banetsu Monogatari – one of the best SL journeys in Japan….
Another reason why the Banetsu West Line is well known to both those exploring Japan by Train and Exploring Japan’s Railways is that it is also the route of the longest Steam Locomotive hauled train route in Japan. The SL Banetsu Monogatari, which is hauled by C57-180. From April thru to November on most weekends and holidays the train does the 221km round trip between Niitsu and Aizuwakamatsu and back.
Places to visit along the Banetsu West Line
We would argue that travelling on the line itself is an adventure in itself, particularly between Aizu Wakamatsu and Niitsu.

Niitsu (新津)- a true railway Town
If there was ever a railway town, Niitsu would be it. it is the starting and end point of three railway lines, including the Banetsu West Line and also has one other major line passing through it. In the days before the shinkansen it was a very railway and railway depot. Niitsu is part of Niigata City. Niigata City Tourist Information: https://www.nvcb.or.jp/multilingual/
It is also home to the J-TREC (owned by JR East) train manufacturing plant. There is also a small railway museum, although this is quite away from the station.
