Siobhan Fitzgerald of Fitch:London believes most consumers already have what they need from products and are looking for added emotional value from packaging.
Frederic Loeb, general manager of brand consultancy &Loeb Innovation, added that he expected other countries to follow Japan's lead, with innovations such as a choice of packaging for the same product and seasonally-led designs.
The predictions were made last week as part of Pack.Vision, a global study carried out ahead of the Global Packaging Exhibition in Paris in November.
The report also predicted that the ageing population would affect trends, with easy-open packs expected to be popular.
