Earlier quoted context omitted.
> my boss assumed that it would be sourcing the bride Are you sure you understood him correctly? That would be highly irregular, to say the least. More likely it was an offer to pay for a matching agency. Arranged marriages between specific people are pretty rare these days, and unheard of outside of family. Unless your boss literally adopted you, he would never take on that responsibility!
I think people are reading rather too much into the phrase "sourcing". Read it as "assumed he'd probably wind up marrying a coworker" and the boss in question is just observing the obvious - workplace marriages are quite common in Japan, especially considering that company employees around that age tend to socialize a lot within the company. One can think of such things as non-pecuniary benefits of a job but I think…
Right, but I also envisioned that they'd be in the awkward position of "hm, but Japanese women won't want a gaijin, obviously ..." and then debating whether they need to call up the "mail order bride" services.
