A Timber Station House on the Asama Plateau
The Former Kusakaru Electric Railway Kita-Karuizawa Station Building (旧草軽電鉄北軽井沢駅駅舎, also written Kyū-Kusakaru Dentetsu Kita-Karuizawa-eki Ekisha) is a single-storey wooden station house in Naganohara Town, Agatsuma District, Gunma Prefecture, built in 1930 and entered on the national register of Tangible Cultural Properties on 29 November 2006.
The railway it belonged to no longer exists. The Kusakaru Electric Railway ran 55.5 kilometres on a narrow 762-millimetre track between Shin-Karuizawa and Kusatsu Onsen, threading across the highland skirts of Mount Asama at an average speed that let passengers pick out individual larch trees. Services began in 1915 and the full route opened in 1926. Typhoon damage and the spread of motor transport ended the southern half of the line in 1960, and the last trains ran in 1962.
Eighteen stations stood along that route. This is the only one left.
The stop opened in 1918 under the name Jizōgawa. What changed its fortunes was the arrival of holiday homes: Matsumuro Itasu, then president of Hosei University, subdivided a large landholding nearby and sold plots to academics, writers and university associates, creating a summer settlement known as the Hosei University Village. The village paid for a new station building and presented it to the railway company, and the stop was renamed Kita-Karuizawa, meaning "north of Karuizawa."
Why the Building Was Registered
Japan's registration system for Tangible Cultural Properties, introduced in 1996, works differently from the older designation system. Registration applies a lighter touch: owners keep freedom to use and adapt the building, in exchange for a duty to notify the government before major alterations. Buildings qualify under one of three criteria, and this station house was registered under the first, as a structure contributing to the historic character of the national landscape.
The Agency for Cultural Affairs record describes it in the compressed vocabulary of architectural survey: timber-framed, one storey, sheet-metal roofing, 68 square metres of floor area. That undersells what is actually a carefully composed piece of design. The main block carries an irimoya hip-and-gable roof finished in sheet metal laid in the kawara-bō manner, with raised battens running down the slope. From this block the entrance porch projects forward under its own irimoya roof, and a chidori-hafu gablet has been added to its flank, so the roofline breaks into a small cascade of triangles rather than a single plane.
Below the eaves the treatment is equally deliberate. The building sits on a dry-laid stone plinth. Walls are shinkabe construction, with the structural posts left exposed against white plaster, and the lower band is clad in sasarago shitami, horizontal boarding held by notched vertical battens. Local accounts say the roof profile was modelled on Zenkōji, the great temple in neighbouring Shinshū, though this is offered as tradition rather than documented fact.
Naganohara Town acquired the building and carried out repair work in 2005. Registration followed the next year, with the Council for Cultural Affairs recommending it in September 2006 and the formal entry made in November.
What to Look For
Start with the transom above the entrance. Set into the openwork is a row of the letter H, picked out in white. It stands for Hosei, the university whose summer colony paid for the building, and it is the reason a rural Japanese station in the mountains of Gunma carries a Roman initial in its woodwork. Visitors who miss it usually walk straight past.
Behind the building, a section of platform and track was reconstructed in July 2010, and on it sits a full-size wooden model of a Deki 12 class electric locomotive. The original machines were built in the United States by the Jeffrey company for mine haulage before being adapted for passenger work here. Their pantographs rose so high above such small bodies that riders nicknamed them kabutomushi, rhinoceros beetles. The replica was designed and built by a local firm at the initiative of a regional consortium of businesses, academics and the town.
There is one more thing worth knowing before you arrive. In 1951 the station appeared in Carmen Comes Home, Japan's first domestically produced colour feature, directed by Kinoshita Keisuke and starring Takamine Hideko. The opening sequence shows the heroine stepping down onto this platform, and a working Deki 12 moves through the frame in colour. Anyone who has seen the film will recognise the building immediately.
Practical points. The exterior, the platform reconstruction and the locomotive replica can be seen at any time, free of charge, and photography outdoors is unrestricted. The interior is managed by the Kita-Karuizawa Tourist Association and is opened to the public without charge on a limited basis, chiefly in summer, and is also used for local exhibitions of painting and photography. Because these openings are seasonal and not fixed, check with the association or the Naganohara Town Office before travelling if seeing inside matters to you.
Getting here is straightforward. Kusakaru Kōtsū buses bound for Kusatsu Onsen leave from the north exit of Karuizawa Station on the Hokuriku Shinkansen and reach the Kita-Karuizawa stop in roughly 40 minutes; the bus stop is on the same rotary as the building. Drivers will find parking in front of the adjacent tourist association office. The site sits at about 1,100 metres, so mornings and evenings in autumn turn cold quickly. Weeping cherries planted around the rotary flower in late spring, well after the blossom has finished in Karuizawa proper.
The neighbouring Kita-Karuizawa Tourist Association building and the Kita-Karuizawa Furusato-kan display further material on the vanished railway, and both are a few steps away.

Q&A
- Can you go inside the Former Kusakaru Electric Railway Kita-Karuizawa Station Building?
- The interior is opened free of charge on a limited seasonal basis, mainly during summer, and is used for community exhibitions at other times. The outside can be viewed at any hour. Contact the Kita-Karuizawa Tourist Association or the Naganohara Town Office to confirm before you travel.
- How do you reach the Kita-Karuizawa Station Building from Karuizawa Station?
- Take a Kusakaru Kōtsū bus toward Kusatsu Onsen from the north exit of Karuizawa Station. The ride to the Kita-Karuizawa stop takes about 40 minutes, and the building faces the rotary where the bus stops. By car it is on National Route 146.
- Is the Kita-Karuizawa Station Building the last surviving Kusakaru Electric Railway station?
- Yes. Eighteen stations stood along the line between Shin-Karuizawa and Kusatsu Onsen. After the railway closed in 1962 the others were demolished, and this is the only station house still standing.
- Why does the Kita-Karuizawa Station Building have the letter H on its entrance?
- The H refers to Hosei University. A summer colony of Hosei-affiliated households, known as the Hosei University Village, funded the new station house and donated it to the railway, and the initial was worked into the transom above the door.
- Is there anything else to see at the Kita-Karuizawa Station Building site?
- A length of platform and track was rebuilt behind the station in 2010, with a full-size wooden replica of a Deki 12 electric locomotive standing on it. The tourist association office and the Kita-Karuizawa Furusato-kan next door hold additional railway material.
