Seriously dude, everything you say is just fucking stupid. You vastly overstate level of foreign ownership of the Japanese economy. The fact is, major native Japanese companies are generally not foreign owned, and it is extremely rare for one to become foreign owned. The Japanese economy is highly insular towards outside companies, and there are numerous measures taken by both Corporate Japan and the Japanese government to keep it that way. Keiretsu are the most famous example and partially exist to prevent massive corporate buyouts, especially by foreign companies. And part of the way they do that is interlocking shareholdings, particularly by banks. The only noteworthy acquisition of a major Japanese company by a foreign entity in recent memory was Foxconn buying out Sharp. And everyone was shocked when it happened because everyone expected Sharp to sell out to another Japanese corporation. Part of the reason the Japanese government and Nissan colluded to remove Carlos Ghosn from power was because he was working to have Renalt takeover Nissan, and the older Japanese corpos (and Japanese government) couldn't stop him any other way. The fact that you think Japan won't act to protect marquee native companies from foreign takeover just shows how ignorant you really are.
And the only thing Japanese that Microsoft got out of the Zenimax deal was Shinji Mikami's company, Tango Gameworks, which isn't a "major" Japanese company by any stretch, but a single video game studio of just 65 people. The only reason they got that is because Tango had been bought by Zenimax when it ran into financial trouble as it was starting up, and the acquisition basically saved the company. If you actually look into it, you will realize that the Japanese video game studios that have fallen to foreign ownership, like RED Entertainment and SNK, are all smaller, Japanese studios, some of which had fallen on hard times in the past.
And with Japan actively trying to decouple itself from China,
to the point of actually paying companies to remove their operations from the country (which they claim to be because of the coronavirus, but probably has more to do with the deteriorating relations between China and the West), any major Chinese investments will almost certainly face government scrutiny and be opposed by the Japanese in principle, because the Japanese, in general,
hate the Chinese, and don't trust them. The only people they hate more, are Koreans. They will happily sell to them, because money is money, but having the likes of Tencent make major moves to buy up large parts of Corporate Japan just isn't happening, which is why they haven't tried to.
