Some scams of disguising imported food as domestic have been recently reported in Japan. Concerning wakame seaweed, which is indispensable in the Japanese diet, the situations is also the same. Most people would not be willing to consume them, if they are from other production areas. Analytical methods for determining the production centers are now definitely needed and such methods should be sensitive to determine any disguising. We found the feasibility using Visible-Nearinfraraed spectroscopy and some chemical information processing methods. In this analysis, we found a clear classification between the China, Kashiwazaki and others because we drew 3-D score plots of the principal component analysis after the variable selection using classification trees.
