Earlier this week, Yahoo Japan, the biggest portal in the nation, said it would being using Google's search engine to power its search instead of following Yahoo Inc.'s decision to use Microsoft's Bing for search.
Microsoft is clearly not happy with the decision.
The software giant has said today it plans to argue before Japan's Fair Trade Commission that the deal is anti-competitive, as it would give Google almost 100 percent of the search market in the region.
Japan is the world's third-largest market for search queries.
The FTC has already said the deal does not violate anti-monopoly laws in the nation.
Yahoo Japan has 57 percent search market share in the country while Google has 37. Microsoft has 2.8 percent.
