New advertising from JWT will break this summer. Media planning will be handled by MindShare Japan, who will work with Asatsu-DK as the buying partner. The Nitori win comes after JWT Japan won business from two other Japanese marketers last year - Unicharm, a leading diaper maker, and Right On, which makes jeans and casual clothing. Although more than 90 per cent of Japanese advertising is handled by domestic agencies, international firms can still expect to grow their operations. As a result of the recession, local corporations are exploring the services of multinational agencies.
