Arashi is a Japanese boy band from Johnny's Jimusho, a very large company that churns out extremely popular boy bands. This particular band debuted in 1999. Somewhere around that time, they had a PV (promotional video, otherwise known as a music video) for their self-titled single directed by Takizawa Hideaki, a member of the Johnny's band Tackey & Tsubasa. While the official PV for the song (not directed by Tackey) was clean and bright, the Tackey version was dark and had the boys dancing around in plastic see-through pants. Somehow somebody somewhere thought it would be a good idea for the boys to perform in the plastic see-through pants. I'm not sure that was a good decision.
