A Brick Pump House Built for Rice Fields
The Former Miidera Pumping Station and Substation (旧三井寺ポンプ所及び変電所, Kyū-Miidera Ponpujo oyobi Hendensho, also written 旧三井寺ポンプ場及び変電所) is a brick building of 1933 at Aza-Miidera, Takamizuma, Mizuma-machi in Kurume City, Fukuoka Prefecture, entered on Japan's national register of Tangible Cultural Properties for buildings on 8 July 2008.
The setting explains the building better than any plan drawing does. Kurume sits on the left bank of the Chikugo River, and the land around Mizuma is flat paddy country where the difference between a good harvest and a failed one has always come down to water. Farmers here organised a land-consolidation district in the early twentieth century and needed river water lifted onto fields that lay above the natural flow. A pumping plant went up in 1914 to do exactly that.
What visitors see today is not that first plant. The 1914 works were replaced on the same duty in 1933 by the brick structure that now carries the registration. Kurume City's own cultural-property inventory still records the property under the year 1914, which is the date the waterworks began rather than the date of the walls now standing; the Agency for Cultural Affairs records the building itself as Shōwa 8, that is 1933.
Three roofed volumes of different heights are joined together. The tallest range runs east and west with a hipped roof at its east end, and it housed the high-lift pumps. A gabled range attached to it held the electrical switchgear that gives the property the second half of its name. A third, lower range on the north side carried a single small pump for the low-lying fields. Floor area comes to 223 square metres.
Why This Waterworks Was Registered
Registration under the 1996 system is lighter than designation as an Important Cultural Property. It records a building as worth keeping and asks the owner to notify the state before altering it, rather than freezing it in place. Each entry cites a criterion. This one was registered as a structure contributing to the historical landscape of the country, which in practice recognises a building that has come to define how a place looks.
The masonry is laid in English bond, alternating courses of headers and stretchers, and roofed with pantiles rather than the slate or metal you might expect on an engineering building of the period. Half-round arched windows open along the east and south ranges. Inside, the roof is carried on king-post trusses. Nothing about the vocabulary is exotic. That is the point: a rural cooperative in 1933 was building with the same industrial grammar used in city warehouses and mill buildings, and doing it well.
Documents kept by the land improvement district record how the work was let. Contracts show local firms carried out the construction, with cement, reinforcing steel, brick, roof tiles and ridge-end tiles supplied in kind. Tiles came from Jōjima and bricks from Araki, both places within reach of the site. Very few farm waterworks of this scale keep their paperwork alongside their fabric.
The pumps themselves are on record. Two units of 200 and 120 horsepower served the higher ground; a single 10-horsepower unit served the lower. Water drawn by the large pair went into a channel along the east side of the building and out to the fields.
What to Look For on a Visit
Come in early summer, when the paddies have just been flooded, and the red brick reads against green and water in a way it never does in a photograph taken in winter. The building sits low and alone among fields, with the offices of the Chikugogawa Land Improvement District nearby.
Walk around it rather than photographing the front. The south gable of the substation range keeps three circular openings, high up, where the incoming power lines once entered. The small north range has its north-west corner cut back on the diagonal, a small piece of shaping that changes the silhouette from every approach. Compare the wall thicknesses if you can: the two larger ranges are two bricks thick, the small pump house one and a half.
The building now goes by the name Agricultural History Museum (農業歴史資料館), and the interior has been fitted out to tell the story of irrigation on the lower Chikugo. Opening is not regular, and visitors have arrived to find the door shut. Anyone hoping to see inside should contact the Chikugogawa Land Improvement District office in advance. The exterior can be viewed at any time from the adjoining road, and photography from outside is unrestricted; the surrounding land is farmed, so keep to the road and field edges.
Getting there is straightforward without a car. Mizuma Station on the Nishitetsu Tenjin Ōmuta Line lies roughly one kilometre east, about 15 to 20 minutes on foot through the paddies. Local trains stop there; express services do not.

Q&A
- Can visitors go inside the Former Miidera Pumping Station and Substation?
- The interior operates as the Agricultural History Museum, but it is not open on a fixed schedule and visitors have found it closed. Contact the Chikugogawa Land Improvement District in Mizuma-machi Takamizuma before travelling if you want to see inside. The exterior is visible from the public road at any hour.
- How do I reach the Former Miidera Pumping Station and Substation by train?
- Take the Nishitetsu Tenjin Ōmuta Line to Mizuma Station, about 25 minutes from Nishitetsu Kurume. The building is roughly one kilometre west, a walk of 15 to 20 minutes across open farmland. Only local trains call at Mizuma.
- Was the Former Miidera Pumping Station and Substation built in 1914 or 1933?
- Both dates appear in official sources because they refer to different things. Pumping began at this site in 1914. The brick building now registered was put up in 1933 to replace the earlier plant, and that is the date recorded by the Agency for Cultural Affairs.
- What does registration as a Tangible Cultural Property mean for the Former Miidera Pumping Station and Substation?
- Registration is a lighter form of protection than designation. The owner may continue to use and repair the building but must notify the national government before significant alteration, demolition or transfer. This property was registered on 8 July 2008 under the criterion for structures contributing to the historical landscape of the country.
- Is photography allowed at the Former Miidera Pumping Station and Substation?
- Photographing the exterior from the adjoining road is unrestricted, and the building is a well-known subject among people who photograph brick industrial architecture. Do not enter the surrounding paddies, which are in active cultivation. For interior photography, ask the land improvement district.
