Tango no Sekku (Boys' Festival / Children's Day)

What Is Tango no Sekku?

May 5 is Tango no Sekku, one of Japan's five seasonal festivals (Gosekku). Traditionally a day to pray for boys' healthy growth, it now coincides with "Children's Day" (Kodomo no Hi), a national holiday, and is widely celebrated as a day of happiness for all children, regardless of gender.

The Origins of Tango no Sekku

What "Tango" Means

• "Tan" means "beginning"
• "Go" refers to the zodiac sign of the Horse (uma), which corresponds to the number 5

The term originally referred to "the first day of the Horse in the fifth month," but later, because of the repetition of the number 5, May 5 itself became fixed as the date of the festival.

The Connection to Iris Leaves (Shōbu)

The fragrant iris plant called shōbu was believed to have the power to ward off evil spirits, and in China there was an old custom of displaying it in May. In Japan, the word "shōbu" is a homophone for another word meaning "to honor the martial spirit," so the festival developed among the warrior class as a day to celebrate the growth of sons.

Symbols of Tango no Sekku

Koinobori (Carp Streamers)

The carp is believed to swim upstream and leap over waterfalls to become a dragon -- a legend known as "tōryūmon" (the dragon gate) -- making it a symbol of success and advancement in life.

Gogatsu Ningyo (May Dolls) and Samurai Helmets

Decorative helmets (kabuto) and armor symbolize protection, expressing the wish to shield children from harm.

Shōbu-yu (Iris Bath)

Floating iris leaves in the bathwater is a custom believed to ward off evil spirits and pray for good health.

Kashiwa Mochi and Chimaki

• Kashiwa mochi: A rice cake wrapped in an oak leaf. Because oak leaves don't fall until new buds appear, they symbolize the continuation and prosperity of a family line.
• Chimaki: A rice dumpling wrapped in bamboo leaves, originating from a Chinese legend and carrying a meaning of warding off misfortune.

Fun Facts About Tango no Sekku

• The common misconception that Children's Day is "a day for boys" is a holdover from Tango no Sekku's origins.
• The streamers (fukinagashi) attached above koinobori are believed to have a protective, evil-warding role.
