Japan’s first “automatic wallpaper pasting machine” and “computerized tatami production
system” releasing craftsmen from heavy labor and allowing them to turn their undivided
attention to work that can only be done by human hands
Since Kyokuto Sanki first opened its doors in 1948, it has continued to grow as amanufacturer of tatami production machinery. A major turning point for the company was
the development of the first prototype of a remarkable “automatic wallpaper pastingmachine” in 1971. However, unlike today’s lightweight 34-kg model, the first prototype
weighed more than 200 kg. But, after a period of trial and error, Kyokuto Sanki had
succeeded in producing 10 lighter machines by the end of the same year, leading to thecreation of the AC-1, Japan’s first automatic wallpaper pasting machine. This machine has
automated the work involved in applying paste to wallpaper, allowing interior decorators toshift their available energy to work that can only be done by human hands (=applying
wallpaper to walls), which improved work efficiency, and as a result, succeeded in increasing
the amount of wallpaper that could be hung.
In 1981, we developed Japan’s first computerized tatami production system, which
automated work that had been carried out manually by craftsmen based on intuition andexperience, and as a result, made it possible for those inheriting tatami shops to be not only
craftsmen, but also corporate managers.
These two products were among the first innovative inventions in Japan, releasing craftsmen
from hard labor and allowing them to focus their attention on work that could only be done
manually by human hands.

［History of development］
Along with changes in Japanese lifestyles, western-style housing took flight in the 1960s,and wallpaper was increasingly used. However, at that time, the work involved was2

labor-intensive because interior craftsmen needed to manually apply glue to the wallpaperusing a brush before it could be hung on the wall. In response to a request for a design for afusuma (paper sliding door) machine in 1970, we started to develop a machine that would
automatically apply paste to wallpaper, eventually creating our “automatic wallpaper pastingmachine.”
Our computerized tatami production system has made it possible to manufacture tatami
mats that were traditionally produced manually by craftsmen by manually measuring
dimensions and laying out tatami one by one in 1 rin (1/100th) or 0.3 mm units, thereby
revolutionizing the tatami production process. We subsequently developed other types ofrelated equipment in quick succession, and succeeded in automating the entire tatami
production process, from measuring the dimensions of a room to layout, cutting, sewing
and fastening corners.

［Originality］
Our continuous challenge in the world of craftsmen where mechanization can be difficult
has provided us with seven core technologies (= special skills) for cutting, measuring,coating and sewing under the concept of automating the handicraft of craftsmen and saving
labor that has been in place since our founding. With our belief system of “always being
original, even in the face of imitations,” we have repeatedly carried out trials based on ourown innovating ideas and delivered equipment that accurately meets our customers’ needs
and seeds and can be adopted on site.

［Future developments］
In 1997, our tatami business division launched a proposal to restructure tatami shops by
super-modernizing production with the introduction of a computerized tatami production
system and improving sales capabilities with consulting and guidance. To date, a number oftatami shops around the country have put structural reforms into place and continue to leadthe industry even today. Our interior business division is also hard at work responding tocustomers’ concerns at worksites to quickly develop new products. In the future, we willcontinue to promote these activities to contribute to the development of the industry andlocal communities.
