Developing Character Merchandise with Fans: Tokyu Power Supply to Begin Accepting Applications for the Participatory Project "Terumaru Public Relations Department" on April 1st

Tokyu Power Supply will hold a participatory workshop titled "Terumaru Public Relations Department," themed around the Tokyu Denki & Gas character "Terumaru," to commemorate the 10th anniversary of the launch of the Tokyu Denki service. Applications for participants will open on April 1, 2026.

This project was born from ideas proposed by our new employees, driven by the desire to "expand the ways to enjoy Terumaru together with those who love the character."

In the workshop, participants will collaborate with professional designers to brainstorm and create original "Terumaru" merchandise. It is a "co-creation" program where participants are involved from the initial idea stage, rather than simply experiencing something prepared by the company.

As we mark 10 years since the liberalization of the electricity market and see a diversification in how services are chosen, our company is committed not only to providing energy but also to creating experiences that make daily life a little more enjoyable. This project is part of that effort, aiming to build new relationships with our customers.

Moving forward, we will continue to roll out various 10th-anniversary special projects that go beyond energy services to add color and fun to your lives.

Please visit the special website for details on the workshop.
