Where the Mill Raised Its Steam
The Tochisen Boiler House (トチセン（旧足利織物）汽罐室) is a brick boiler house of the early Taisho era (extended in 1941) in Fukui-cho, Ashikaga City, Tochigi Prefecture, and was registered as a Registered Tangible Cultural Property (structure) on March 7, 2008 (Agency for Cultural Affairs).
The Agency records a single-storey brick building with a slate roof and a building area of 239 square metres, registered together with two boilers; registration number 09-0170.
Twin Gables and Lancashire Boilers
The Tochisen Boiler House is a single-storey brick building in the south-west corner of the mill site, roofed with two parallel gables of corrugated slate (Agency for Cultural Affairs). The northern gable wall ends in a peak, while the southern wing, a later addition, has a square-topped end wall. The walls are laid in English bond with pilasters.
Ashikaga City describes the building as three wings running north to south behind the printing factory. The north wing dates from the founding of the works in 1913 to 1916 and first held Lancashire boilers No. 1 and No. 2. A middle wing added in 1941 still contains boilers No. 3 and No. 4, which were registered along with the building. South of that, a steel-framed wing added in the late Showa 30s, roughly the early 1960s, holds No. 5, a horizontal multi-tube boiler.
The Agency records two roofs and two boilers, while the city's account covers three wings and boilers numbered 1 to 5; the registration appears to cover the brick north wing and the 1941 extension.
Why It Was Registered
The Agency points to the Lancashire boilers installed inside and to the black camouflage paint that still survives, a trace of the war years; it was registered for its contribution to the historic landscape.
Ashikaga City calls the boiler house indispensable to a textile mill and, with the printing and saran factories registered earlier, a valuable architectural survival.
What to Look For
The first thing to notice is the black camouflage paint that survives on the walls (Agency for Cultural Affairs). Painting over the red brick was presumably meant to keep the building from standing out to aircraft.
Compare the gable walls as well: a peak on the original north wing and a square top on the 1941 extension (Agency for Cultural Affairs), the same brick handled differently a generation apart. Inside, the Lancashire boilers are large horizontal cylinders.
Visiting
Ashikaga City lists the Tochisen Boiler House as normally closed to the public. It stands in the south-west corner of the Tochisen Co., Ltd. mill site, behind the printing factory, so chances to see the boilers inside are limited.
