Go! Go! Itsutsugo Land (ゴーゴー五つ子ら・ん・ど, Go go itsutsugo ra·n·do) is a Japanese anime series that originally aired in Japan during 2001 and 2002 on TBS. The series is about quintuplets who have many adventures together.

The series has been dubbed into English by The Ocean Group as Let's Go Quintuplets! and aired in New Zealand.^[1] The first two episodes of the English dub were released on a dual audio European Spanish DVD.^[2]

The series totals 50 episodes, each one consisting of 1 to 2 parts.

The name Go! Go! Itsutsugo has a double meaning. Go is, apart from the English word, also Japanese for "five". Itsutsugo means quintuplet.

The names of the characters were changed in the English dub but the initials of each name were preserved.

• Karl Miller (森野かぶと, Morino Kabuto) is the oldest of the five twins, although only by a few minutes.
• Krystal Miller (森野きのこ, Morino Kinoko) is the most self-centered. She already knows she is going to become a movie star and therefore gives signed autographs away.
• Harold Miller (森野ひのき, Morino Hinoki) is the bookworm and wants to win the Nobel Prize.
• Austin Miller (森野あらし, Morino Arashi) wants to become a true superhero - a detective or something else.
• Karly Miller (森野こだま, Morino Kodama) is the youngest of the quintuplets. She wants to save the world and all animals (except frogs)
• Six Miller (ロクちゃん, Roku-chan) is an affectionate little dog owned by the Miller (Morino) family.

Note: of most of the episodes the English dub name isn't known.
