BGB Communications was appointed following a competitive pitch to attract travellers to ANA's daily Heathrow to Tokyo service via a trade and consumer media relations campaign.
BGB director Fiona Reece said: 'Although ANA is a household name in Japan, there is low awareness of the airline in the UK.'
The agency will also target executives through corporate intranets, newsletters and promotions. BGB is promoting ANA's in-flight technology and its 'unparalleled' passenger service.
ANA is targeting banking, technology, pharma and automotive workers.
