Formal Ocho

Formal Ocho is a traditional origami butterfly often used in wedding ceremonies. Ocho is the male butterfly whereas Mecho is the female butterfly. These paper butterflies adorn sake bottles or sake serving kettles (choshi) during traditional Japanese weddings.

Mecho and Ocho are rarely seen except in formal ceremonies; however, these two butterflies are historically important since they are the first examples of representational origami.

This information is derived from "Wrapping Origami" by Yoshihide Momotani (1993). Momotani gives instructions for 3 pairs of paper butterflies:
  • Classical Mecho & Ocho (from Kayaragusa)
  • Formal Mecho & Ocho (Traditional), and
  • Regular Mecho & Ocho (Traditional)
The terms "formal" and "regular" will be used to maintain consistency.

Below are instructions to fold the formal version of Ocho.



In step 4, fold only the top layers. Allow the back flaps to swivel towards the front.




In step 10, allow the back flaps to swivel towards the front.
