Founded in 1970 in Chiba, Japan, Seikosha has grown from a traditional signage company into a multinational advertising network, with a presence in Vietnam, Myanmar, Hong Kong, and the Philippines.

In Vietnam, we were among the first agencies to provide comprehensive Out-of-Home (OOH) advertising solutions—from strategic consulting and creative design to production and custom billboard construction. With a deep understanding of the local market, Seikosha optimizes media locations to deliver the highest visibility and impact for our clients’ brands. We place customer satisfaction at the center of everything we do through:

Legal Compliance & Quality: Strict quality control and commitment to technical safety standards.

Transparency & Dedication: Clear and regular reporting, honest communication, and flexible, prompt problem-solving.
Driven by a spirit of continuous innovation, Seikosha is proud to be a strategic partner, supporting our clients’ success and sustainable growth.
