Message from
the President & CEO Issho-Kenmei(Utmost Diligence)

My name is Yasuhiro Hiraoka, President and CEO of Hiraoka Sangyo Co., Ltd. and the E&H Precision Group.
Our company’s roots trace back to 1774, when our ancestor, Jizaemon Hiraoka, enshrined a sacred spirit from Fushimi Inari Taisha in Kyoto, praying for the prosperity of our family business and the peace of the local community. Later, in 1907, my great-grandfather, Seizaburo Hiraoka, founded Hiraoka Textile, launching modern production of futon fabric—Ome bedding textiles—in collaboration with Toyota Industries Corporation.
Thanks to the wholehearted dedication of our founder and employees, we overcame the hardships of the Greater East Asia War and numerous economic crises, laying the foundation for today’s company. In 1972, recognizing the structural decline in the textile industry, we changed our name to Hiraoka Sangyo Co., Ltd. and shifted our focus to metal cutting and machining using automatic lathes. As a late entrant to the metal processing industry, we started small, and the early days were filled with challenges.

In 1995, amid these circumstances, we made a decisive move to revitalize the business by forming a joint venture with Eto Co., Ltd., a trading company specializing in metal components. Together, we established E&H Precision (Thailand) Co., Ltd. in the Amata City Chonburi Industrial Estate in the Kingdom of Thailand as a precision metal cutting company. Later, in 2010, we established E&H Precision India Pvt. Ltd. in the Neemrana Industrial Area, Rajasthan, Republic of India. In both cases, we were the first Japanese automatic lathe processing company to enter these markets, paving the way as a pioneer.

With the generous support of Thailand and India, we have been fortunate to benefit from both countries’ economic growth. As a result, the E&H brand has earned widespread trust for our QCDS—Quality, Cost, Delivery, and Service—and we have solidified our position as a leading Japanese automatic lathe machining company in Asia. Our gratitude toward Thailand and India is deep and enduring.

In 2008, we suspended domestic manufacturing in Japan and consolidated all production operations in Thailand and India. Then, in 2021, we made E&H a wholly owned subsidiary. Since then, we have promoted localization and local workforce development under the concept of becoming a Wakyo precision machining company—referring to Japanese entrepreneurs and professionals who establish businesses overseas while embracing local cultures.

Guided by our slogan “Issho-Kenmei” (wholehearted dedication), we strive to instill our core philosophy throughout the company, foster a family-like atmosphere, cultivate positive habits, and create an uplifting workplace culture. Our ultimate goals are to become a company truly needed by our customers, to maintain appropriate profitability for sustainability, and to contribute to local communities through the growth of our employees.
With a vision to become the world’s leading automatic lathe machining company, we continue to take on new challenges in advanced machining fields. Our aim is to secure a prominent place in the global precision machining industry and become an indispensable partner to clients across many sectors.

The 21st century is the era of Emerging Asia. As a Wakyo machining company, we are deeply rooted in this dynamic region, taking on new challenges with sincerity and resolve. Looking ahead, we will continue to pursue growth opportunities—committed to contributing meaningfully to the development of both Asia and our home country, Japan, through business innovation and the growth of our people.
We sincerely appreciate your continued guidance and support.
Thank you very much.

Issho-Kenmei(Utmost Diligence)

The company is like a family brought together in a relationship of mutual trust. All members of the company shall work honestly, diligently and in good faith. The company is urgently needed by customers all around the world, and we shall secure the profits necessary to achieve continuous growth for the company, which is the foundation of our daily lives.

Vision

The world's leading
automatic lathe machining company

  • 1 The most advanced automatic lathe
    processing technology in the world.

    This means mastering processing technologies and production processes capable of manufacturing products at lower costs, faster and with better quality than any other company in the world. It also means receiving a wide variety of orders for items able to be processed via automatic lathe and providing parts and services for every industry in the world.

  • 2 The ability to achieve
    independent global expansion.

    This means the ability to be sensitive to environmental changes and to personally pioneer markets throughout the world.
    In order to achieve this, our company shall continuously improve our market insight, our commitment, our fighting spirit and our ability to form relationships of mutual trust with customers, and we shall pass these abilities on to future generations.

  • 3 The ability to standardize.

    This means creating mechanisms that repeatedly improve business through utilization of IT and the ability to apply the mechanisms in a way that thoroughly conveys the endeavor to all related personnel in all business centers. And as a result, it means boasting productivity that is decidedly superior to that of rival companies.

Value

Standards of Thought

The idea of personal responsibility and
a sense of contribution.

When a problem occurs, blaming it on others doesn’t solve anything. Better team work is achieved not by blaming others but by considering what you personally can do. In addition, it's important that we think and behave from the perspective of “the company is a family that everyone should work to protect, so we shall ask not what the company can do for me but rather what I can do for the company.”

Code of Conduct

Speed and thoroughness

Speed means prompt action. We shall endeavor to take action promptly on initiatives and issue, and to determine concrete dates for items that cannot be acted on immediately and enter them into our plans. We shall promptly produce output without being too focused on perfection and strive to increase precision from there. Thoroughness means carrying through until completion. We shall continuously endeavor to achieve our plans even when confronted by difficulties by engrossing ourselves in our task and involving related personnel. At the same time, we shall appropriately ascertain the feasibility and effectiveness of our plans, reexamine them as necessary, and continue to take actions that produce results.
