Toshiba's Vegeta refrigerator brand is teaming up again with one of Dragon Ball Z's toughest fighters to promote its appliances. This marks the Saiyan Prince's fourth campaign: with the company and this time its titled "Fresh Five Star Vegeta Campaign". The tie-in started on July 7 and will run until August 31.

Participants can win prizes by hunting down the Dragon Ball hidden on the campaign site and following the instructions. All participants need is an active Twitter account to win. The instructions will ask participants to tweet with the hashtag #真ん中の○○○, where the "○○○" will be replaced with the location of the Dragon Ball found on the website. Users that that include the correct hashtag will be entered in a lottery to win Bluetooth headphones, a smartphone cover, or tickets to the upcoming Dragon Ball Super film.

Vegeta's previous stint as an appliance salesman included a campaign that gave away free produce and okinomiyaki spatula sets. The Dragon Ball cast also promoted Kirin Beverage and gave participants a chance to make their own character and even win a 3D figure.
