A Village Built Its Own Power Station
The Former Kamikuge Village Kamitaki Power Station (旧上久下村営上滝発電所, Kyū Kamikuge-son'ei Kamitaki Hatsudensho) is a brick hydroelectric building of 1922 standing on the right bank of the Sasayama River in Sannan-chō, Tamba City, Hyōgo Prefecture, entered on Japan's national register of Tangible Cultural Properties on 18 April 2008.
The scale surprises people who arrive expecting an industrial plant. The Agency for Cultural Affairs gives the dimensions as 9.2 metres along the ridge by 6.5 metres across, a building area of 59 square metres. Two brick storeys under a gabled tiled roof, with a bridge counted as part of the registered property. A generous domestic garage would not be far off.
Look at the brickwork itself. The bond is English, headers and stretchers alternating by course, laid by masons working a long way from any city. Ground-floor openings are rectangular double-hung sashes. The upper storey carries segmental arches, that flattened curve which sits somewhere between a lintel and a proper semicircle, and which gives the little building most of its dignity.
Lamplight to Electric Light
Kamikuge was a village of oil lamps in 1920 when its residents agreed to fund a hydroelectric scheme themselves. Work started that December. The station was finished in June 1922 and began sending current on 8 January 1923. Water came by an existing agricultural channel rather than a purpose-built canal; enthusiast surveys of the site record an effective head of 18.9 metres and an output near 70 kilowatts, figures worth treating as approximate.
Wartime consolidation of the electricity industry absorbed the plant into Kansai Haiden, forerunner of Kansai Electric Power. It kept running until 1963, when a breakdown stopped it. No repair followed.
Registration, and the Dinosaur Underneath
Registration number 28-0355 was granted under the criterion of contribution to the historic landscape of the nation, with public notice on 7 May 2008. Ownership rests with Tamba City. What is being recognised here is a category of infrastructure that has almost vanished: small generating plants built and run by the communities that used the power, before national grids and corporate utilities absorbed them.
The building also owes its survival to a piece of luck that has nothing to do with electricity. In August 2006, fossils were found in the riverbed directly below, in the Early Cretaceous mudstones of the Sasayama Group. They belonged to a titanosauriform sauropod later named Tambatitanis amicitiae and known locally as the Tamba dinosaur, one of very few new genera and species described in Japan. Attention that arrived for the fossils spilled onto the derelict brick shed above them.
Conservation work followed, and the building reopened on 11 February 2010 as the Tamba City Former Kamikuge Village Kamitaki Power Station Memorial Hall. The interior now carries panels and film on how the plant worked and on the fossil site below. A small hydroelectric unit of around 500 watts has been installed, supplying part of the building's own electricity, so the place generates once more on a modest scale.
Visiting
Tamba City's management regulation sets opening hours at 10:00 to 16:00. The hall closes on Mondays and Tuesdays, with the closure shifting to the next non-holiday when either day falls on a public holiday, and again over the new year period of 29 December to 3 January. Tourism listings report free admission. Because staffing is limited and the schedule can shift for local events, a call ahead is sensible.
The approach rewards a little planning. JR Shimotaki Station on the Fukuchiyama Line lies roughly 1.5 kilometres away. A viewing platform beside the building looks down on the fossil excavation site, with casts on display, and a stairway at the side of the hall drops toward the river, which means the exterior can be studied properly even on a closed day.
Kawashiro Gorge runs east and west for about four kilometres here, cut through the sedimentary beds of the Sasayama Group, and Kawashiro Park nearby has a 90-metre suspension bridge over the water. Cherry trees along the bank draw crowds in early April. Photography of the exterior presents no difficulty; rules for the interior are not published, so ask on arrival.

Q&A
- Can I go inside the Former Kamikuge Village Kamitaki Power Station, and what are the opening hours?
- Yes. It operates as a memorial hall under Tamba City. The city's regulation sets hours at 10:00 to 16:00, with closure on Mondays and Tuesdays (shifted when these fall on public holidays) and from 29 December to 3 January. Tourism listings report that entry is free.
- How do I get to the Former Kamikuge Village Kamitaki Power Station?
- JR Shimotaki Station on the Fukuchiyama Line is the nearest railway access, about 1.5 kilometres from the site. Most visitors arrive by car, and the memorial hall sits directly beside the Tamba dinosaur fossil discovery site with its viewing platform.
- Why is the Former Kamikuge Village Kamitaki Power Station a registered cultural property?
- It was registered on 18 April 2008 under registration number 28-0355 for contributing to the historic landscape of the nation. Its particular interest lies in being a hydroelectric plant that a village financed, built and ran on its own account, a form of local infrastructure that has almost entirely disappeared.
- What is the connection between the Former Kamikuge Village Kamitaki Power Station and the Tamba dinosaur?
- Fossils were found in August 2006 in the bed of the Sasayama River immediately below the building. They were later described as Tambatitanis amicitiae. The publicity around the discovery brought attention to the disused power station, which was then conserved and reopened as a memorial hall in February 2010.
- How big is the Former Kamikuge Village Kamitaki Power Station building?
- Small. The Agency for Cultural Affairs records 9.2 metres by 6.5 metres and a building area of 59 square metres, in two storeys of brick laid in English bond under a gabled tiled roof. An associated bridge forms part of the registered property.
