Karaage is often translated as Japanese fried chicken. It consists of smaller, boneless chicken pieces fried with Japanese seasoning. Not really chicken nuggets because the chicken is not minced.
It is so popular and traditional that it has its own trade organization, The Japan Karaage Association, which holds promotional events in stores all across the country. Interestingly, there are regional karaage varieties, and in the Miyazaki area, tartar sauce is used with karaage. So the Japan Karaage Association and the Lawson convenience store chain have collaborated on developing Miyazaki tartar flavored karaage for sale in stores. It appears the tartar flavor is in the batter, so you don't have to bother with separate tartar sauce packets.
The chicken character on the package is Karaage-kun, the Japan Karaage Association mascot.
