I wasn't talking about selling consoles in Japan (even though it would help MS in the long run to maybe get e foot on the market). I was talking about showing japaneses devs and fans of japanese games that you take this gaming culture from there serious so that they support Xbox more.
I get your point. But the problem is that I doubt MS will risk pouring a large sum of money into it. It would be a nice sign for Japanese devs that they care about the market, but at this point it is impossible to establish a studio in Japan for Microsoft without having huge losses for the first few years. And their current leadership doesn't really like to risk. They are very careful with what they do. So, I don't expect MS under Nadella to take such risk even if it can possibly benefit them in the future and increase their marketshare in the Japanese market.
Although, the xCloud seems like a step in the right direction in terms of appeal to Japanese customers. It is obvious that they can't sell consoles to them for whatever reason, Japanese just don't buy them. (100k is the worst sales number in Japan for any console in 30-40 years). But Japanese like handheld devices and gaming on the go. Switch is a major success there for the most part because of its portability. So, maybe xCloud will be a perfect approach for someone who likes mobile gaming.
