The front door of an early Showa training hall
The Tomioka City Social Education Center Entrance and Office Building (富岡市社会教育館玄関及び事務室棟) is a single-storey timber building in Ichinomiya, Tomioka City, Gunma Prefecture, completed in 1936 and registered as a Registered Tangible Cultural Property on July 8, 2008. It was the entrance wing of the Tōgoku Keishin Dōjō, a training hall paid for by donations from Gunma residents after Emperor Showa visited nearby Nukisaki Shrine in 1934.
The building faces south from almost the exact center of a site that sits on raised ground. It covers 193 square metres under a hipped roof (Yosemune-zukuri) of Sangawara-buki pantiles, with only the eaves finished in sheet iron.
Inside, the plan is simple: a corridor runs along the north side, with the office, the director's room and other rooms lined up to the south of it. Reception and administration share one roof, and nearly 90 years on the building still serves as the center's front desk and office.
Two doorways and a very straight roof
There are two ways in. On the east side a gabled carriage porch (Kirizuma-zukuri, entered from the gable end) projects toward the forecourt; farther west is a secondary entrance known as the ni-no-kuchi, the "second door." Pairing a formal porch with a plainer side entrance under one roof makes the difference in rank easy to read.
The Agency for Cultural Affairs singles out the porch roof, noting its gentle pitch and ruler-straight lines as the building's most striking feature. There are no temple-style curves here. Formality comes from restraint, a habit typical of the modern Japanese-style architecture of the early Showa era.
Tomioka City, describing the complex as a whole, likewise puts this porch and its Shikidai step at the top of its list. The design came from the Oe Kokufu Kenchikujuku, the studio led by the architect Oe Shintaro, and within its staggered line of wings the Tomioka City Social Education Center Entrance and Office Building plays the role of the public face.
The auditorium, the lecturers' room building, the Japanese-style room building and the main gate were registered the same day. Of the five, this is the one that most clearly announces where the front of the complex is.
What to look for
The main gate stands southwest of the porch. On the way from gate to porch, pause and look at the porch at an angle from the west: you see the triangle of its gable and the shallow slope of its roof in a single view.
Stand under the porch and you can see how the shikidai leads up into the building. This is where visitors in 1936 first stepped inside.
Then turn to the ni-no-kuchi to the west and compare. Along the eaves of the main hipped roof runs a thin band of sheet iron edging the tiles, a finish shared by all five registered structures and repeated on the auditorium and the gate.
From the front of the Tomioka City Social Education Center Entrance and Office Building, look left and right: the roofs of the other wings step back in stages. This is the best spot to take in the staggered plan as a whole.
Visiting
The Tomioka City Social Education Center Entrance and Office Building still works as the center's reception and office, so on opening days you can walk in through the entrance. Admission is free.
The porch and the ni-no-kuchi can be viewed from the grounds at any time during opening hours. The office itself is a working room, so say a word at reception before looking in.
No official guidance on photography could be found. Photographing the exterior is unlikely to be an issue, but check at reception before taking pictures indoors or of other users. Opening hours, closing days and directions are on the page for Tomioka City Social Education Center as a whole.
