The Japanese government has been accused of using tsunami relief funding to support its struggling whaling industry.
The International Fund for Animal Welfare's (IFAW) report - The Economics of Japanese Whaling - was published today, following a year of research into the industry.
Japan-based agencies commissioned by IFAW conducted the research, presenting the "clearest picture ever" of the failing whaling industry, IFAW reported.
Data based on government figures show that government subsidies, which usually average about 782 million yen (NZ$1.1 million) annually, increased by about 2.28 billion yen (NZ$29.2 million) last year.
IFAW said it wants Japan to move towards whale watching instead of whaling, which the findings show to be unprofitable and catered to a shrinking market.
