Ichibata Electric Railway Nunosaki Substation

The Building That Makes the Trains Move

The Ichibata Densha Nunosaki Substation (一畑電車布崎変電所, also written Ichibata Densha Nunozaki Hendensho) stands immediately west of Nunosaki Station in Taku-cho, Izumo City, Shimane Prefecture, was completed in 1927 and extended in 1954, and was entered on Japan's Register of Tangible Cultural Properties on 26 January 2011.

It exists because of a decision taken in the mid-1920s. The Ichibata line had opened in 1914 as a light railway worked by steam, and the tracks reached Nunosaki in February 1915 on their way to the village of Ichibata. When the company began planning an extension towards Matsue, it chose electrification over more locomotives. Electrification requires somewhere to receive high-voltage supply, convert it and feed it to the overhead wire, and Nunosaki was picked for that job. Electric trains started running between Izumo Imaichi and Ichibata in October 1927.

The building is a plain rectangle of reinforced concrete: two storeys under a flat roof, twenty metres across the front, sixteen deep, with a total floor area of 289 square metres. A second phase went up in 1954, so the fabric carries two dates and two moments in the railway's fortunes.

The corporate name on the register belongs to the present operator, Ichibata Densha Co., Ltd., which took over rail operations in April 2006. Its predecessor, Ichibata Electric Railway, built the substation and gave the company at Izumo Taisha-mae the older style of name that still appears on that property's listing.

Why a Utility Building Was Registered

Registration came in the sixty-ninth round, on 26 January 2011, under number 32-0159. The criterion applied was contribution to the historic landscape of the country, the same test used for this company's Izumo Taisha-mae station building fifteen years earlier. The operator's own account of the listing puts the reasoning more directly: a building that no account of Japanese railway management and industrial history can leave out.

The architectural interest sits in the original western portion. Its elevation is symmetrical and strictly rectilinear, articulated by pilasters that run through both storeys in one unbroken vertical, what classical vocabulary calls a giant order. Beneath the window openings the concrete is worked into corbels. None of that was required to shelter transformers. Somebody in 1927 took the view that a machine building on a rural branch line ought to be composed rather than merely erected.

The Agency for Cultural Affairs description attaches these features specifically to the western original block, so the 1954 addition can be read against it rather than confused with it. Comparing the two halves along the front is the most rewarding thing an outside observer can do here.

One quality separates this substation from most registered industrial buildings. It never stopped working. The operator states that the plant has remained in active service since it opened, a span now approaching a century, still supplying the current that the trains draw down from the wire. Conservation in this case has not meant retirement, conversion to a café or reassembly in an open-air museum. The listing recognises a machine that is still doing its original job.

Seeing It from the Platform

One thing should be clear before anyone travels here. This is live electrical plant, not a visitor attraction. The interior is closed, and there are no tours, no opening hours and no admission arrangements. What a visitor can do is look at the outside from public ground, which is enough to take in the elevation the register describes.

The simplest approach is to alight at Nunosaki, station 10 on the Kita-Matsue Line. It is an unstaffed halt with a single platform set on a tight curve, so there is a noticeable gap when stepping down from the train. The substation stands immediately to the west, under a minute away on foot, and the two-storey concrete block reads clearly against the low houses around it.

Passengers who stay aboard get a compressed version. Trains between Unshu-Hirata and Koyukan-Shineki run directly alongside the building, and it fills the window for a few seconds before the curve takes it away.

Just west of the station flows the Funakawa, a channel once used to move goods by boat between the town of Hirata and the villages around it. Standing on the platform puts two generations of transport infrastructure in a single view: the water route that carried the district's freight before the railway arrived, and the concrete box that powered what replaced it.

Practical points. Nunosaki has a toilet inside the gate and no ticket window, so buy a ticket in advance or settle the fare on board. Photography from the road and the platform is unrestricted, though there is little point aiming a lens through fencing at operating equipment. The station cannot accommodate handle-type wheelchairs, and passengers needing assistance are asked to contact the operator's sales office beforehand on 0853-62-3383, weekdays 9:00 to 17:00. Anyone wanting to see both of Ichibata's registered properties in a day should change at Kawato for the Taisha Line and allow the better part of an afternoon.
