You may have already seen this if you're a huge Gackt fan, but if not, Gackt's official website has a fantastic collection of Gackt quotes to ponder over under the title "Gackt WORD" (Japanese link). I'll post a couple of choice quotes below with translations.

1. "With each sadness a woman gets more beautiful. I wonder if with each sadness a man gets stronger."



2. "My definitive fragrance for however many years is Channel's 'Egoist.' The Platinum version."



3. "I'm the most natural when I'm naked. I'm often buck-naked at home."



4. "The brightest place in my house is the bathroom."

Update: Gackt's latest "Platinum Box" has just been announced!

Update 2: Fixed the translation on the first quote.

The original Japanese quotes from Gackt's website:

1. "Onna no ko wa kanashimi no kazu dake kirei ni natteiku kedo, otoko wa kanashimi no kazu dake tsuyoku natteikunn ja nai kana"



2. "Boku jishin ga mo nannen mo 'jibun no nioi' toshite kimeteiru no wa, Channel no Egoist, Platinum no ho."



3. "Ichiban shizen de irareru no wa hadaka de iru toki. Heya de wa (suppon)pon de iru koto ga ooi yo."



4. "Uchi de ichiban akarui basho wa toilet."
