The band POT, known for “getting the crowd going,” has been selected for the role, with Harada playing the vocalist. As Harada says in the making-of video, “President, you’re a real challenger,” this innovative and unique collaboration has been realized. Now in his third year as an image model, the video concludes with a loud, “When you think of Harada, you think of Kumagai Denko!”, reaffirming the bond between Harada and the company. Harada held a “Fukashi Taro” stick in place of a microphone, and the POT members’ costumes incorporated “Nukusa ni Kubittake” (We’re Crazy About Warmth) designs, adding a special touch to the production’s presentation, sprinkling Kumagai Electric products throughout. Also, please pay attention to POT’s song “YASUMASA” (using the president’s name), which was written specifically for this commercial. Interview with Ryuji Harada The band POT heats up the dance floor, and Kumagai Denko heats up the bath… whoever came up with this collaboration is incredible (laughs). I was actually in a band when I was younger, so being a part of POT allowed me to relive that passion for the first time in a long time, and it was a really fun shoot. I personally can’t live without my “Nukusani Kubittake” when I’m shooting outdoors in the winter or for YouTube videos. I also hope that people will learn about and use “Fukashi Taro,” which can be used in situations where gas is unavailable during disasters that can happen at any time, through this commercial.

http://bro.co.jp/concept.html POT Interview This time, I received an offer from Kumagai Denko to write a song. The concepts of “heating up the dance floor” and “heating up the bath” were very easy to create, and I was able to create a great song and create the best live commercial. I was a little nervous before meeting Harada-san, but when we met and talked and filmed the live performance, he was so funny that it blew me away (lol), and I had a really fun time filming. I’ll continue to do live performances, so I hope you’ll continue to support me! POT
