Sanshin Day (Sanshin no Hi)

What Is Sanshin Day?

Every year on March 4th, Japan observes "Sanshin Day" (Sanshin no Hi). Established in 1993 by Ryukyu Broadcasting Corporation (RBC), this day promotes familiarity with the sanshin, Okinawa's iconic traditional three-stringed instrument, and helps pass on Okinawan culture. The date comes from the number wordplay "san (3) - shi (4) - n," which sounds like "sanshin." On this day, sanshin enthusiasts in Okinawa and around the world gather to perform the celebratory traditional song "Kajadefu" together at the same time.

Historical Facts About Ryukyu Culture and the Sanshin

For centuries, the sanshin has been deeply woven into Okinawan identity, from the royal court music of the Ryukyu Kingdom to everyday life among ordinary people.

• The sanshin's roots: The instrument descends from the Chinese "sanxian," introduced to the Ryukyu Islands in the late 14th century and gradually transformed through local innovation into today's sanshin.
• Spreading to mainland Japan: Around the 16th century, the instrument traveled from Okinawa to Sakai (near Osaka), where it was further modified into the shamisen — a pivotal moment in the spread of instrumental culture across Japan.
• The sound of peace: After World War II, in POW camps and similar places, people made "kankara sanshin" out of empty cans and parachute cord, singing and dancing to heal hearts — a powerful story of resilience and recovery.

Fascinating Facts About the Sanshin

• The secret of snake skin: Traditional sanshin use python skin, which holds up well against climate changes and produces a distinctively powerful yet delicate tone.
• Kunkunshi notation: Sanshin music is written in a unique notation system called "kunkunshi," which uses kanji characters to indicate finger positions — a system still used today.
• Ebony necks: Among the woods used for the sanshin's neck, ebony — called "kuruchi" in Okinawan — is especially prized for its density and beautiful tone, making it a top-grade choice.
• The plectrum (bachi): Players typically wear a plectrum carved from water buffalo horn on their index finger, though in folk music styles, playing with bare fingers is also common.
• A guardian in the home: In many Okinawan households, the sanshin is displayed in the place of honor (tokonoma), treated almost like a household guardian that protects the home and brings good fortune.
