The Three Key Strengths of TOYO-RO

More than just making technology — it’s support capability.

To support the front lines of manufacturing, we continuously refine our responsiveness.
• A year-round maintenance system.
• A legacy of technology passed down through generations.
• Integrated production from design through manufacturing.

Our mission is not only to make—but to support.

Maintenance

Maintenance support throughout the year.
We value relationships that begin with repairs.

At TOYO-RO, we provide maintenance services for repairs and equipment issues 362 days a year (excluding the New Year holidays). Guided by our principle, Go to the site first, our specialized staff visit sites directly, both in Japan and overseas. The knowledge gained on-site is used to support further improvements and development, leading to higher-quality manufacturing.
