Short Answer
Overview
The koto (箏, also written 古筝) is a traditional Japanese plucked string instrument belonging to the zither family. Its most common form has a long, hollow wooden body and thirteen silk or nylon strings stretched over movable bridges, allowing performers to alter pitch and tuning easily. Played with three finger picks (tsume) attached to the right hand, the koto produces a resonant, harp‑like timbre that has become synonymous with Japanese classical and folk music.
Although originally associated with the aristocratic court music of the Heian period, the koto has evolved through centuries to encompass a wide range of styles, from solo repertoire (solo koto) to ensemble settings such as sankyoku (koto, shamisen, and shakuhachi) and modern crossover projects. Its versatility and distinctive sound continue to inspire composers worldwide.
History / Origin
The word “koto” derives from the Japanese characters 箏 or 琴, both historically used to denote stringed instruments. The instrument itself was introduced to Japan from China during the Nara (710–794) and Heian (794–1185) periods, where it was initially known as the “gagaku koto” and performed in court ensembles. By the Edo period (1603–1868), the koto had been adapted for the emerging merchant class, leading to the development of the 13‑string version that remains standard today.
How It’s Used
In traditional settings, the koto is featured in gagaku (imperial court music), sankyoku chamber music, and folk genres such as min’yō. Contemporary musicians employ the instrument in jazz, film scores, and experimental electronic music, often using amplified pickups or digital sampling. Notated in western staff notation or traditional Japanese tablature (koto‑gakufu), the koto’s movable bridges enable micro‑tonal adjustments, making it adaptable to various tuning systems.
Why It Matters
The koto is a cultural emblem of Japan, representing centuries of artistic refinement and social change. Its repertoire includes classic pieces like “Sakura” and “Rokudan,” which are taught in music schools nationwide. Internationally, composers such as Toru Takemitsu and John Cage have incorporated the koto into avant‑garde works, highlighting its capacity to bridge Eastern and Western musical traditions.
Common Misconceptions

The koto is only a classical instrument.
The koto is used in folk, pop, jazz, and electronic music, and many contemporary artists perform it outside traditional contexts.
The koto is tuned to a fixed scale.
Its movable bridges allow performers to retune each string for different modes, scales, or micro‑tonal intervals.
