DISCO has been promoting activities to realize a sustainable society based on DISCO’s corporate philosophy, DISCO VALUES, and DISCO VISION, which clearly outlines the state that DISCO aspires to achieve 10 years in the future in the form of milestones that exist in order to enable us to implement DISCO VALUES.

DISCO VALUES Management Guidelines


DISCO VALUES, DISCO’s corporate philosophy established in 1997, clarifies the social mission (Mission), which is the role that DISCO intends to play in the society, and the corporate target (Target) necessary for DISCO to firmly forge ahead to achieve this Mission.


Bringing faraway science to comfortable living through advanced ‘Kiru’, ‘Kezuru’, ‘Migaku’ technologies


Our technology and services are to become international standards, bringing delight worldwide

By achieving excellence in all of our corporate activities, our existence will be welcomed by our stakeholders and society

“Advanced Kiru, Kezuru and Migaku technologies” is DISCO’s business domain. In other words, DISCO will never deviate from the three technology fields of Kiru (cutting), Kezuru (grinding), and Migaku (polishing) in our business activities. The company’s social mission is to connect the ever-advancing science to bountiful and comfortable lifestyles via these core technologies. For this purpose, DISCO believes that the most important thing is to increase value-exchange with our stakeholders.

In 2002, in order to make it easier for all DISCO members, including both officers and employees, to behave and make decisions in line with our Mission and Target stated above, on top of carrying out daily corporate activities and business operations, over 200 detailed statements were added to DISCO VALUES as “Management Guidelines”. To this day, in order to enable all our employees to act and make decisions according to DISCO VALUES in their daily activities, DISCO has been consistently implementing activities to further this initiative, such as company-wide workshops and workplace-based study sessions.

DISCO’s Definition of Growth as a Company

In addition, DISCO does not think of growth in terms of the expansion of the company’s sales, size, or market share. For DISCO, “growth” as mentioned in DISCO VALUES is defined as how close we come to achieving our Mission, the increase in value-exchange with our stakeholders, such as employees, customers, and shareholders compared to the previous year, and whether we further contributed to society.

Growth of DISCO


DISCO VISION plays the role of a mid-term milestone that clearly outlines the future state that DISCO aspires to achieve and the goals toward which it should strive on the path to achieving our Mission.

DISCO VISION was established in 1997, and activities were first started with 2010 as the target. When we reached the target year of 2010, we reviewed our progress and activities thus far, and established DISCO VISION 2020 with the aim of pursuing further evolution for the next 10 years.

As with the previous VISION, we reviewed our activities thus far, and established DISCO VISION 2030 from a future perspective aiming at further evolution. This VISION defines not only quantitative targets such as sales and profits, but also includes qualitative targets.
This VISION clearly defines the goals that DISCO aims to achieve by 2030 from multiple angles: the Element Angle, which elucidates what the corporation is based on its main elements, such as the business, organization, and human resources, and the Stakeholder Angle, which focuses on the relationship between DISCO and our predominant stakeholders.
In this way, at DISCO, instead of implementing management plans that are focused on the present, we conduct our business activities by creating management plans reversely formulated from the future state that we want to achieve, our VISION, and strive to achieve even higher ideals.

An Excerpt from the Management Guidelines, DISCO Values

A portion of the statements is as follows.

General Principles of Management

  • DISCO VALUES is shared throughout DISCO on a worldwide scale.
  • DISCO conducts stakeholder-oriented management. “Highly transparent governance” is absolutely required.
  • The manner to maintain steady and favorable relationships with stakeholders, such as customers, employees and shareholders, is a vital management issue.
    And, consistently confirming the increase in value-exchangeability between DISCO and its stakeholders is the key to the issue.
  • Organizational management supports operational management. Executives must be professionals in organizational management.
  • The implementation of DISCO VALUES is an important role of management. Management that does not take DISCO VALUES into consideration cannot be regarded as DISCO’s management.
  • Humans have evolved technology and civilization, bringing affluence to society and our lives. DISCO will also evolve its technology and organization to become more valuable to society.
  • The essence of corporate activities is to serve society. Evolution is a way to achieve that.
  • DISCO is fair in all its corporate activities.
  • DISCO proceeds with a spirit of openness and fairness. Therefore, DISCO’s management must not create an environment that generates negativity, must discourage negativity, and must never conceal negativity.
  • “Fairness” is important at DISCO. It should be asserted without being affected by emotion or the general atmosphere. An example of this would be the expression, “justice overrides harmony.”
  • Disregard for human rights is not condoned in DISCO’s corporate activities.
  • DISCO disavows any use of forced labor in its corporate activities.
  • DISCO disavows any use of child labor in its corporate activities.
  • Consideration for the environment, health, and safety is a common principle to all corporate activities.
  • Be loyal to the principles and always reconfirm the principles and the goal. Above all, place importance on the essentials. Forgetting these fundamentals puts the organization at risk.
  • Avoiding or concealing the need for a recall is a betrayal of the stakeholders and benefits nobody.
  • Risk management is intended to protect the stakeholders. DISCO ensures thorough risk management.
  • Stable supply, as well as reliability, are the duties of manufacturers.
  • DISCO will continue to conduct its business no matter the contingency. This will reassure our stakeholders.
  • “Create a company with which customers feel comfortable doing business.”
    “Create a company where the constituent members feel comfortable working.”
    This is the vision of Business Continuity Management (BCM).
  • DISCO and its employees exchange value. They mutually aim to improve this exchange.
  • Equal opportunity is given and equitably rewarded.
  • A successful result is not evaluated if it is done without regard to DISCO VALUES.

Human Resources

  • The capability of an individual increases many times over via organic interaction with others.
  • People can demonstrate their abilities to the fullest extent when they act based on their own intent. DISCO places importance on the manifestation of each member’s individual intent.
  • Displays of originality and capability depend on the intent of each member. DISCO encourages such intentions and ambitions.
  • DISCO establishes an environment in which those suited to be members of the organization may continue to perform for as long as possible.
  • Personal and family values may differ among individuals. Neither the corporation nor its employees seek to interfere in the individual matters of its employees.
  • DISCO does not discriminate or evaluate employees based on personal attributes such as biological sex, sexual orientation, gender identity, age, nationality, race, religion, or educational background.

Line of Business

  • Application Engineering, products, and services all together constitute our Line of Business.
  • After-sales service and customer complaints should be perceived as opportunities to find new customer needs.


  • DISCO always keeps in mind the brilliance of “going for it”.
  • The creation of a strong patent map is imperative in order to protect DISCO's business and reassure its customers.


  • DISCO has the responsibility to provide a stable supply of first class products to our customers.


  • Money is not the goal but the means to accomplish DISCO’s mission.
  • DISCO does not pursue Money that does not comply with DISCO VALUES.
  • DISCO only depends on Money generated from business and “quality investment.”
  • Profits are to be invested in the reproduction of value. Returning profits to our stakeholders is based on the same idea.
  • DISCO does not speculate when investing or using funds. DISCO only makes investments that contribute to our growth.
  • Whether money is “clean” or “dirty” depends on the people who handle it. DISCO’s Money has nothing to do with “easy money.”


  • Buying is an important function which can enhance DISCO’s products.
  • In DISCO’s Buying, the suppliers should be given equal information, be selected fairly, and receive the correct payment.
  • DISCO and its suppliers are on an equal footing. As partners participating in DISCO’s business, they should be treated with respect. DISCO’s Buying should never create a bad impression.
  • Solid relationships with suppliers are a very important company asset. It would be disastrous to damage them.
  • In selecting a supplier, we should correctly understand the true state of their company as well as the quality of their products.
  • No transactions are to take place with suppliers who do not take the environment, human rights, etc., into account at a consistently high standard.
  • DISCO throughly implements responsible mineral procurement.
  • DISCO does not use products or parts made from conflict minerals.
  • DISCO does not procure products that use forced labor.
  • DISCO does not procure products that use child labor.
  • When equal offers are made, our preference is given to suppliers “who have a higher sense of social responsibility,” such as for the environment and human rights, as well as to suppliers from the local community to which DISCO belongs.


  • Selling is the act of realizing optimal value-exchange between DISCO and its customers.
  • DISCO’s Selling is not to offer the products but the value generated by doing business with DISCO.


  • The quality of an Organization is determined by the quality of its members. Therefore, DISCO’s Organization should consist of high-quality members.
  • Escalation is the duty of all constituent members so the full potential of the organization can be realized.

Corporate Social Relations

  • Being a good corporate citizen forms the basis of DISCO’s Corporate Social Relations.
  • DISCO would like to be a company that serves as a good “member of society.” As such, DISCO is comprised of good “members of society.”
  • Corporations exist because society exists. The bare minimum requirement is to be a good corporate citizen.
  • Relations between DISCO and society should always be considered, and efforts to maintain the relationships expended.
  • DISCO’s constituent members are members of society and are also involved in the creation of a relationship with society.
  • Appropriate payment of taxes is the foundation for creating a relationship with society.

Corporate Culture

  • The core of DISCO’s Corporate Culture is DISCO VALUES.
  • High-quality Corporate Culture is a long-lasting source of vitality for an organization.
