A team of activists campaigning to remove Japan’s “rising sun flag” says it will send complaints to PR agents of companies responsible for some 40 cases in which the controversial design was used.

Professor Seo Kyung-duk of Sungshin Women's University and his team said Wednesday that the Japanese World War II flag design was found in tourist pamphlets, burger wraps and other items for commercial use worldwide. 

Seo said he and his staff members will secure the contact information of PR officials from the companies and send them letters of protest together with campaign materials.
