Developing Character Merchandise Together with Fans: Tokyu Power Supply Starts Recruiting Participants for the 'Terumaru PR Department' Participatory Project on April 1

Tokyu Power Supply will implement a participatory workshop called the 'Terumaru PR Department' themed around the Tokyu Denki & Gas mascot character 'Terumaru', to commemorate the 10th anniversary of the start of the Tokyu Denki service, and will begin accepting applications for participants starting April 1, 2026.

This project was born from an idea by a new employee of our company, triggered by the desire to 'expand the ways to enjoy Terumaru together with people who love the mascot.'

In the workshop, participants will share ideas and plan/produce original 'Terumaru' merchandise together with professional designers. It is a 'co-creation' style program where participants are involved from the idea generation stage, rather than just experiencing what the company has pre-prepared.

As we reach 10 years since the deregulation of electricity and as the ways people choose services diversify, our company is working not just to provide energy, but also to create experiences that make everyday life a little more enjoyable. This project is a part of that effort, aiming to build a new relationship with our customers.

Moving forward, our company will continue to transmit various 10th-anniversary special projects that add color and joy to everyone's lives, going beyond merely providing energy services.

For details of the workshop, please visit the special website.
