Tosoh Acquires Naming Rights for Multipurpose Cultural Venue

Tokyo, Japan–Tosoh has entered a three-year agreement for the right to rename the Cybele Arena in Yamagata City, Yamagata Prefecture, at a yearly cost of ¥20 million (approximately US$186,000). This multipurpose cultural venue is operated by GEN, a regional culture foundation, a public interest incorporated foundation that provides support for regional culture. On April 1, the venue was renamed the Tosoh Arena.

This is the first time Tosoh has acquired naming rights. That it has done so regarding a multipurpose cultural venue in Yamagata Prefecture is most appropriate given the company’s well-established roots in the business and social fabric of this region of Japan. Tosoh’s annual payment for the naming rights to the Tosoh Arena will bolster that complex’s ability to remain a vibrant center of regional culture. In short, Tosoh will contribute to the development of regional culture and society.

The acquisition of naming rights will also heighten awareness throughout Yamagata Prefecture of the Tosoh Group, and serve as a reminder of the depth of Tosoh’s commitment to its corporate social responsibility.
