Kappa Sushi, one of Japan’s most popular kaiten sushi chains is offering all-you-can-eat sushi for FREE. All the conveyor-belt sushi restaurant asks in return is recording a video of your experience and upload it to YouTube. Anyone with a YouTube channel with 100,000 or more subscribers can submit an application form. If chosen, applicants will be contacted by Kappa Sushi to set up the specific date and time to visit.
