Maybe they also think that a foreign woman might expect from their man that he’s telling his feelings straight out several times a day, something a shy Japanese man just won’t do.
Another problem is that many of the Japanese men seem to be afraid of their English ability and thus fail to approach a foreign woman.
Things that they fear a foreign woman would not agree to do (e.g.
stay home, take care of the kids, always pour new alcohol into his empty glass etc.).
For some reason (maybe through the consumption of too many Hollywood movies) Japanese women think that foreign men are like that!
They’re not afraid of showing their feelings in public or telling their girls flat out how they feel about them. The extreme version of this is known as “gaijin hunter” and some will do everything for the sake of having one of those adorable “half”-kids (half Western, half Japanese) just to toss their foreign guy later on.
For some guys it really gets to their heads and they start bragging about it like crazy as part of the superstar syndrome.
