"Pikanchi Double" (stylized as PIKA★★NCHI DOUBLE) is the twelfth single of the Japanese boy band Arashi. The single was released on 18 February 2004 in two editions: a regular edition containing the karaoke versions of all the songs released in the single, and a limited edition with a deluxe cover art and a bonus track. 
   "Pikanchi Double" was used as the theme song for the direct-to-video movie Pikanchi: Life is Hard Dakara Happy, the sequel to the group's first movie together. The single's typography is also modified to denote it as a sequel, with two glyphs filling a void, instead of a single glyph with a void in the middle as seen in the typography of "Pikanchi".
