"On-site report: Yokota Manufacturing Co."
500 types of products, build-to-order
Attention to detail in meeting customer needs
While the overall mission of industry can be summarized in the words "quality
over quantity", these words hold especially true for Yokota Manufacturing
Co. Yokota is a consistent manufacturer from order and casting to machining,
assembly and sale of pumps, valves, and check valves. Yokota is an order-made
manufacturer, and does not do large-scale line production or maintain stock
in storage facilities.
Company president Hiroshi Yokota, expressing confidence in his company's
strategies, explains, "There are mountains of big companies manufacturing
pumps and valves domestically. However, for a medium-small enterprise such
as ours to survive, it is imperative that we pursue a path using our originally
developed technology covering a vast array of product types manufactured
in small quantities that meet even the smallest needs of our customers."
Yokota stands out as a pump manufacturer developing pumps made of rust-free
stainless steel for pumping seawater in aquarium and power generation plants,
as well as especially challenging applications such as the pumping of liquid
mixed with bubbles, or sludge. Yokota manufactures nearly 500 types of
products daily, but "No one product is made exactly the same,"
comments senior managing director Mario Miura.

The manufacturing system is also original. Manufacturing related personnel
are rotated for fixed periods of time through casting, machining, assembly
and testing branches. This is Yokota's specialty, called the "Job
rotation system", which provides experience to workers in all of the
manufacturing processes. Some may say that this only provides a mediocre
level of technical development for personnel, however, Yokota's president
refutes, "We ensure thorough technical training of personnel in each
process. What I'm aiming for is 'general specialists' who have acquired
specialized technical skills as well as knowledge of an overall manufacturing
It is standard practice during times of recession for manufacturers to
consolidate facilities by dividing labor and increasing production lines
in the manufacturing process. However, Yokota's president criticizes this
approach saying, "Dividing labor has the effect of relieving the sense
of responsibility for the product." Rather than throwing in the latest
facilities and equipment into the manufacturing site, Yokota's manufacturing
system is run on tried-and-true machinery and the skills of its employees.
Yokota's president explains, "Throwing in capital and depending on
machines would be the same as what big manufacturers do. We've got brains
and experience, and having only that we can be confident in remaining unbeaten."
He goes on to say, "However, the realities dictate the necessity of
investing capital in marketing." Yokota is working at a feverish pitch
to strengthen its sales and marketing performance.
Everyone at Yokota carries business cards with the slogan, "Water
at your command!" Employees coined the phrase, which is being registered
as a trademark, as symbolic words that succinctly describe the company
as a pump manufacturer dealing with water. Adding further meaning to this
phrase, Yokota's president comments, "In dealing with a substance
as common to the world as water, it is necessary to generate ideas based
on a firm understanding of the principles of nature, and that surpass accepted
The company was established in 1948. Development and manufacturing focused
on the pumping out of spring water from coal mining sites. As any pump
defect could affect lives under such conditions imposed by coal mining
sites, it was imperative for Yokota to have meticulous operation efficiency
down to the finest detail at the manufacturing site. It can be said that
Yokota, of course, has had a great deal of confidence in its product precision.
Yokota's president comments, "Simple is best. The conditions for our
company's survival include making products full of simplicity and originality
that please the customer through their use." Even after over 50 years,
this business stance remains unchanged.

Expansion to 500kg capacity melting furnace
Yokota launches private power generation
[Hiroshima] Yokota Manufacturing Co., Ltd. (Location: 1-3-6 Minami
Yoshijima, Naka-ku, Hiroshima, President: Hiroshi Yokota, Tel: 082-241-8672)
will install an additional stainless steel melting furnace with a 500kg
capacity in conjunction with its power unit renovation project related
to the introduction of a private power generation system. The additional
melting furnace variation will aid the pumping process of liquid stainless
steel, reducing costs. Yokota expects to start the new melting furnace's
operation from the end of August with an expected cost of about 30,000,000
Yokota is a consistent pump and valve manufacturer from ordering, casting,
and assembly to distribution. Currently, Yokota has stainless steel melting
furnaces with capacities of 1.2tons, 600kg, and 200kg. However, due to
the number of diversified orders from customers, cases of equipment and
facilities mismatching have occurred, resulting in inefficiencies.

Due to this, Yokota has constructed a private power generation system powered
by two turbines with an output of 240kW as a first step. The renovation
of the power unit and the provision of an assured power supply have allowed
the introduction of new equipment.
Although the private power generation system was also introduced for the
purposes of cost reduction, electrical expenses including operation costs
have not changed from the previous system where power was purchased.
According to Mario Miura, senior managing director, cost reductions can
be achieved both in productivity and improved efficiency when the additional
furnace goes into full-scale operation and the expanded production system
is put into place.
