Japan's farm ministry said Friday it has newly registered three products, including "Japanese tea," under its geographical indication protection system aimed at safeguarding brands of agricultural and fishery products as imitations spread overseas. Once registered, products can be sold with a GI mark, and the ministry hopes the move will boost exports. The GI system, which is similar to those used in Europe, aims to protect regional specialties and prevent their unauthorized use by third parties. The ministry said it plans to expand the system, and details about how to register products can be found on the 世界杯买球网.
