Etymology

 * The name Taiki means "big, great" (大) (tai) and "brightness, radiance, shine, sparkle, gleam, twinkle" (輝) (ki).
 * Taiki's surname Himekawa means "princess, young lady of noble birth" (姫) (hime) and "river, stream" (川) (kawa).

Trivia

 * Taiki does not own eye contacts and chooses to deliberately go without them. When portraying characters without glasses, he will simply not wear them. This is because, according to his belief, actors are able to portray characters only using their movements. And even without glasses he would be able to make to their general movements.
