The building that fed the trams
Meiji Village Meitetsu Iwakura Substation (明治村名鉄岩倉変電所, Meijimura Meitetsu Iwakura Hendensho) is an electrical substation of 1912 standing at the Meiji Mura museum in Inuyama, Aichi Prefecture, and listed as a Registered Tangible Cultural Property in 2004.
It was built in what is now the city of Iwakura, Aichi Prefecture. The Nagoya Electric Railway had put streetcars on the roads of Nagoya in 1898 and then pushed its lines out across the Owari plain. According to the museum, the Iwakura substation went up when the company opened its Inuyama line. Its job was to take power off the transmission network, convert it into a form the trains could use, and feed it to the overhead wire.
The building was dismantled in 1974, once its working life had ended, and moved to Meiji Mura the following year, in 1975. The building area is 151 square meters. It has only one storey, but the walls run high because large switching and conversion machinery had to stand inside.
Why Meiji Village Meitetsu Iwakura Substation was listed
The building was registered on 17 February 2004 under registration number 23-0120, with the criterion that it offers a model of design. What earned the listing is the way an engineering requirement, a tall weathertight box for machinery, was allowed to shape the architecture rather than be hidden by it.
The original was brickwork, single storey, under a Kirizuma-zukuri gabled roof covered in natural slate, with the gable walls carried up above the roof line. Buttresses brace all four corners. The openings are semicircular arches finished with generous keystones, and the fanlight above each is divided into 3 parts by mullions. The roof is carried on a timber queen post truss.
What stands today is not, however, the same fabric. The Agency for Cultural Affairs database records that the main structure was changed to reinforced concrete during the relocation and faced with brick tile. The form and the detailing of a brick building carried over; the bricks themselves stopped doing structural work. For anyone thinking about what registration actually protects in Japan, this building makes the question concrete.
What to look for
The rear wall, where the design collects
Walk around the back. That elevation is handled quite differently from the other three: semicircular arches, segmental arches, pilasters and recessed panels, a run of variations on how brick can be laid. None of it is decoration for its own sake. Insulators were mounted on this face, and the current left the building here for the overhead line. The side carrying the most equipment got the most attention.
Tall windows and a brown band
The flanks carry tall narrow windows fitted with sash frames, each topped by a semicircular fanlight. Brown brick runs across the wall in 4 bands, drawing horizontal lines over the red field. The windows also frame the view out across district 5 of the museum, and the building looks different again from the inside out.
Look up at the truss
There is no ceiling. The roof space is left exposed, so the timber queen post truss is fully visible: paired posts hanging a horizontal member and keeping the centre of the span clear. The reason is practical. Heavy equipment needed floor space uninterrupted by columns. The best thing inside Meiji Village Meitetsu Iwakura Substation is neither the floor nor the walls but the ceiling that was never built.
Visiting Meiji Village Meitetsu Iwakura Substation
The substation is an exhibit building at Meiji Mura, at plot 66 in district 5 of the museum. Individual buildings do not carry their own charge; one entrance ticket covers the site. Some areas are fenced for safety, and buildings occasionally shut for repair.
Admission runs 2,500 yen for adults, 1,500 yen for high school students, and 700 yen for junior high and elementary school pupils, with children below school age admitted free (checked September 2026). Groups of 20 or more pay a reduced rate, and there is an annual pass called Meijimura Jūmin Tōroku.
Hours move with the season. April to July, September, October and March are 9:30 a.m. to 5:00 p.m.; August is 10:00 a.m. to 5:00 p.m.; November is 9:30 a.m. to 4:00 p.m., with Saturdays and public holidays extended to 5:00 p.m.; December to February is 10:00 a.m. to 4:00 p.m. The gate stops selling tickets 30 minutes before closing, and closure days are set irregularly, so check the museum calendar first.
Personal photography is unrestricted. Tripods may not be used inside buildings, and photography from within the wooded areas is forbidden. The brickwork on the rear elevation repays a visit when the light reaches it rather than at midday.
Buses for Meiji Mura leave from the east exit of Inuyama Station on the Meitetsu network, and direct services run from Nagoya Station and Sakae. By car it is 3 kilometers from the Komaki-higashi interchange on the Chūō Expressway, with parking outside the north gate at 1,000 yen for a standard car. District 5 sits on the north gate side of the grounds. The site is hilly, so the shuttle bus that circles the village stops is worth using.
