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.
