Exploring Tango no Sekku: Unraveling Japan's Vibrant Boys' Day Festival of Flags


Japan is a land of rich history and fascinating cultural traditions. One of the most vibrant and captivating celebrations is Tango no Sekku, also known as Boys' Day or the Festival of Flags. This annual event, which takes place on the 5th of May, honors the happiness and health of young boys across the nation. If you're interested in Japanese culture, join us as we explore the customs, food, and rich history of this unique event.

History of Tango no Sekku

The origins of Tango no Sekku can be traced back to ancient China, where a similar festival was held to celebrate the start of spring. As the tradition spread to Japan, it evolved into a celebration of young boys and their future success. The 5th day of the 5th month was chosen for the festival, as the number five is considered auspicious in Japanese culture. Over time, Tango no Sekku has also been influenced by samurai culture, with many of the customs and symbols associated with the warrior class.

Koinobori: The Symbol of Tango no Sekku

One of the most iconic symbols of the Boys' Day celebration is the koinobori, colorful carp-shaped windsocks that are hung outside homes and public spaces. The carp is a symbol of strength and perseverance in Japanese culture, as it is known for its ability to swim upstream against strong currents. By flying the koinobori, families wish for their sons to grow up strong and resilient, just like the carp.

Koinobori come in various sizes and colors, with each color representing a different family member. The largest carp, usually black, symbolizes the father, followed by a smaller red or pink carp for the mother. The children are represented by smaller, brightly colored carp, with the youngest child's carp at the bottom of the pole.

Customs and Celebrations

On Tango no Sekku, families with young boys gather to celebrate and pray for their children's health and happiness. Traditional activities include the display of samurai dolls and helmets, which are believed to bring good fortune and protection to the household. These intricate displays are passed down through generations and serve as a reminder of the family's heritage and the virtues of the samurai.

Another popular custom is the preparation of special foods for the occasion. Some of the most popular dishes include kashiwa-mochi (rice cakes filled with sweet red bean paste and wrapped in oak leaves) and chimaki (sweet dumplings wrapped in bamboo leaves). These treats are believed to bring luck and prosperity to those who enjoy them during the festival.

Tango no Sekku Today

Although Tango no Sekku has traditionally been a celebration of young boys, in 1948, the Japanese government declared the 5th of May as Children's Day, a national holiday to celebrate the happiness of all children. As a result, many families now celebrate both boys and girls on this day, and the event has become more inclusive. However, the customs and traditions of Tango no Sekku, such as the koinobori and samurai displays, continue to be an essential part of the celebrations.
