Why are light-haired male love interests common?


It is relatively common for series (especially shoujo) for the/a love interest
to be blond. This appears in [Ouran High School Host
Club](http://images4.wikia.nocookie.net/__cb20110902130942/ouran/images/8/80/Tamaki-
suoh.jpg), [Kaichou wa Maid-
Sama](http://images.wikia.com/kaichouwamaidsama/images/6/61/Takumi-Usui.jpg),
[Tokyo Mew
Mew](http://images1.wikia.nocookie.net/__cb20100217122721/tokyomewmewpower/images/1/1c/Blue_Knight.png),
and a number of others. Why is this common in Japan, where the population is
98.5% ethnically Japanese--and as such naturally dark-haired--and most of the
rest of the population is either Chinese or Korean?




It might have something to do with the representation of the blonde-color.
According
[here](http://tvtropes.org/pmwiki/pmwiki.php/UsefulNotes.HairColorInJapan),

> Blonde hair on a male character may imply that he is a trickster.
> Alternately, it may symbolize that this character is a focus of chaos, and
> trouble follows him wherever he goes, such as Vash the Stampede from Trigun,
> or Soichiro Nagi from Tenjou Tenge; a live-action example is the movie
> version of Battle Royale's Kazuo Kiriyama. It is also not uncommon for anime
> males with long blonde hair to be portrayed as Casanova-types. (Examples:
> Kurz from Full Metal Panic, Allen Schezar from Vision of Escaflowne, Kyle
> from Suikoden V among others...)
