I want to know the answer to the following question:
What two console manufacturers dominate the Japanese market?
All the background I'm provided with is that "Edge magazine reported in August 2011 that initially lackluster and subsequently falling sales in Japan, where Microsoft had been unable to make serious inroads into the dominance of domestic rivals Sony and Nintendo, had led to retailers scaling down and in some cases discontinuing sales of the Xbox 360 completely.". Is that enough to answer the question?
Answer: yes
