Yep, you can get the basic gist from translate & the actual Japanese is rather close to it. It is quickly becoming apparent with this & also the ex-employee story which came out today that he very much liked the high life. The area this house is in, as the article says, is well known for company CEOs to live in. Rumor had it the CEO of McDonalds lived near there as well (hence the McDonalds at that station was always really good & had excellent service lol). I lived not far from there a few years ago, though in an infinitely cheaper apt.

The exact wording about the move to Canada is something like MK's life became busy & then at the End of Jan his wife told someone (probably a neighbor) that she suddenly had to move to Canada. It doesn't say whether she blamed his work for her move when she told whoever it was though. 
The Japanese media can be quite invasive when they want to be & quite w/out impunity, so if this story grows in Japan I'm sure someone will dig him up. Although I daresay he's just holed up in that luxury apt & living via Amazon prime.
