Joint Road Service Co., Ltd.（ジョイントロードサービス株式会社） is a road construction and traffic safety facilities contractor based in Amagasaki, Hyogo, Japan. Its business is centered on the Kansai region, including Osaka and Hyogo, while also taking on projects related to expressways nationwide, Japan’s Ministry of Land, Infrastructure, Transport and Tourism, and major general contractors. The website is a corporate site, mainly presenting the company’s qualifications, service scope, recruitment information, and contact details.
Its core services include road marking work, signage installation, sound barrier construction, protective fence installation, special paving, general civil engineering, and other road facility works. The official site explicitly lists use cases such as pedestrian crossings, center lines, parking lot markings, road guidance signs, regulatory and warning signs, guardrails, rockfall protection, bridge protection, and colored pavement. The company holds a construction business license from Japan’s Minister of Land, Infrastructure, Transport and Tourism, and publicly discloses ISO 9001, ISO 14001, and ISO 45001 certifications, indicating a relatively standardized system for quality, environmental, and safety management.
The official website does not publish any standard quotes, unit price lists, or packages. This type of work depends heavily on site conditions, construction area, traffic control requirements, material specifications, project timeline, and location. In most cases, customers need to submit requirements by phone or email, after which the company provides a quote based on an on-site inspection or drawing review.
The advantages are that the company focuses on traffic safety infrastructure, with relatively complete disclosure of its qualifications and major clients. Its key clients include local governments, expressway companies, and large road construction firms, which gives it strong credibility. Its services also cover road markings, signage, guardrails, sound barriers, paving, and civil engineering, making it suitable for integrated road safety improvement projects. The drawbacks are that the website is more of a corporate profile, with limited detailed case studies, before-and-after construction comparisons, quotation procedures, or service SLA information. The interface is only in Japanese, which is not very friendly for non-Japanese customers.
It is suitable for Japanese local governments, road management agencies, expressway-related organizations, construction general contractors, property owners or parking lot operators, as well as job seekers who want to work in road construction in the Kansai region. It is not suitable for users looking for standardized online services or remotely delivered overseas services.
This is a standard Japanese corporate website and can usually be accessed directly from mainland China. However, actual project delivery depends heavily on local Japanese qualifications, on-site construction, and Japanese-language communication.
