The man only gets a small allowance every week or month and needs to ask his wife for permission if he wants to spend any more of his own hard-earned money!
Foreign guys often seem to struggle with this system.
I personally know a few couples where either the man or the woman is foreign and I noticed quite a lot of differences in the kind of relationship they have.
Please note that the following is based on my personal experience and that not everybody out there is like that.
In relationships where the man is foreign I noticed that they mostly speak his native language.
Although they live in Japan and sometimes even have children together who also speak Japanese, the foreign guys don’t / can’t speak Japanese.
At least getting one woman after another into your bed, is really easy, even if you’re quite ugly!
