Sanshin & Eisa
Three-string music, drum dance and communal identity
Sanshin & Eisa
The three-stringed guitar covered with python skin and the Obon drum beat - twin beats in the soul of the Uchinanchu people.
If nature is the body of Okinawa, then Sanshin and Eisa are its cultural lifeblood. On one side is the cooing voice of the royal organ that has lived for more than 600 years; On one side is the roaring sound of drums calling the ancestors back every summer. This article analyzes both from their history, construction, techniques, performance structures, modern transformations to the identity role of the global Okinawan community.
Two symbols, one soul
Sanshin and Eisa are often mentioned together, but they belong to two complementary worlds: one is musical instrument the sophistication of the living room and the royal court, one is collective performance art of streets and festivals. Their intersection is sound — Sanshin's voice leads Eisa's footsteps.
Sanshin (三線) — voice of Okinawa
Three-stringed guitar with python leather body and black ebony neck. It is both a solo instrument and singing accompaniment (uta-sanshin), and the heart of Ryukyu court music and island folk songs (shima-uta). Considered a family heirloom.
Eisa (エイサー) — dance to call ancestors
Group drum dance of young people during Obon ceremony to send off and honor the souls of ancestors. Combining taiko drums, paranku hand drums, chants and Sanshin — explode into the festive colors of an Okinawan summer.
From a Chinese instrument to Ryukyu treasures
Sanshin has the root word sanxian (sanxuan) of China, introduced to Ryukyu through trade in the late 14th century. In Okinawa and the Amami Islands, it evolved into a separate musical instrument — which in turn was the ancestor of the tree shamisen famous in Japan.
Late 14th century · Introduced
Sanxian from China followed the trade route to the Ryukyu Kingdom — the origin of Sanshin.
15th century · Nobility
The priestly class (Ryukyu samurai) was encouraged to study Sanshin; The instrument gradually became associated with Shuri court culture.
16th century · Spread to Japan
Sanshin arrives at Sakai port (Osaka), converted into shamisen then spread throughout Japan (Tsugaru shamisen, gottan...).
Early 17th century · Official court musical instrument
Sanshin became the main instrument of court music; The court established a position to manage luthier makers, giving birth to top-notch crafting masters. Along with the development of Kumiodori.
1879 · Popularized to the people
The kingdom was annexed as Okinawa Prefecture; The nobles lost their status and dispersed to the regions, unintentionally bringing Sanshin to the masses, giving rise to the folk song genre.
1945 · "Kankara Sanshin"
After the Battle of Okinawa, in a prisoner-of-war camp, people made makeshift instruments from canned meat (kankara) and parachute cords — a symbol of unquenchable cultural vitality.
Today · Renaissance & technology
March 4 is "Sanshin Day"; Companies like Yamaha collaborate to measure and digitize tones and manufacturing techniques to preserve them for the future.
Anatomy of a Sanshin tree
Long approx 75–80 cm, smaller than shamisen. The appearance is simple but hides sophisticated craftsmanship passed down from dynastic times: choosing wood, drying it for many years, covering it with leather, adjusting the tone.
🪵 Guitar neck Star / 棹
Usually made from a block of black ebony "kuruchi" (kokutan) — a precious dark wood; Also uses isunoki wood. The wood is dried for up to ~3 years, then chiseled, trimmed, and covered with glossy black lacquer.
🐍 Leather covered body Chiiga
The resonator is covered with python skin (usually Burmese python/reticulated python) imported from Southeast Asia — a unique feature of Sanshin compared to shamisen.
🎻 Three strings Nunui-jiru
The three strings (uujiru – low string, nakajiru – middle string, miijiru – high string) are traditionally made of silk, but now more durable synthetic fibers are often used.
👆 Plectrum Bachi/tsume
Pluck with a horn (buffalo) claw worn on the right index finger, plucking one string at a time — different from the shamisen's way of playing large pieces.
🎚️ Tuning shaft Karakui
Three wooden shafts at the top of the instrument for tuning; cultivating the rope is called chindami.
🎁 Lucky pair Mitu-sanshin
Ancient people displayed a pair of Sanshin made from the same wood on a wall niche for good luck, or kept it in a lacquer box as a family heirloom.
Kunkunshi, tuning and musical genres
Sanshin did not copy music using Western notes but with kunkunshi — a unique notation system that uses Chinese characters to indicate finger positions on the fretboard. Combined with several tunings, it creates a distinctly Okinawan sound palette.
Kunkunshi (工工四) — ancient pronunciation
Born in connection with the Shuri court music tradition, kunkunshi records the position of the strings in Chinese characters on a square frame, along with lyrics and lick symbols. This is a key tool to help transmit and popularize Ryukyu court music through many generations.
- Read in columns, each character = one finger position.
- Include lyrics and tempo, sometimes even notes for vocals.
- The "difficult" character (long press on the lever) is usually marked separately.
Winding styles (chindami)
| Type | Characteristics |
|---|---|
| Honchoshi 本調子 | Correct tuning, the foundation of most lessons. |
| Ni-age 二揚げ | Raise the middle string — a poignant tone, often for lyrical songs. |
| San-sage 三下げ | Lower the third string — creating a soft, distinct tone. |
Music genres associated with Sanshin
Imperial classical music (koten)
The style is solemn and slow-paced, associated with Ryukyu and Kumiodori court dance. Featured song: "Kajadifu bushi" — played in front of the king. Poetry sung in form ryuka (8–6 syllables).
Island folk songs (shima-uta / min'yo)
The voice is everyday, close, telling stories of love, homeland, and labor. From here, "uta-sanshin" music (playing and singing) and modern Okinawan music exploded.
Kachashi
Jubilant improvisational music and dance closed all the fun; Everyone waved their arms and danced freely to the bustling Sanshin rhythm.
Uta-sanshin
The tradition of "integrated singing and singing": the voice and the instrument blend into one - the core of the performance jikata undertake in Eisa.
Not just musical instruments
For Okinawans, Sanshin is an object associated with life's milestones: celebrations, funerals, village festivals, and awamori drinking nights. The saying "where there are Okinawans, there is Sanshin" reflects its central location.
The dance to send off the soul
Eisa originates from dance Obon (Bon Odori) — a ceremony where young people dance in each village to welcome and send off the souls of their ancestors. The origin is much debated, but has existed at least 400–500 years.
Roots of Buddhism
A famous hypothesis: tall monk Taichu Shonin spread the chanting style of Pure Land Buddhism; The drum-beat chants gradually transformed into the folk songs that the Eisa team sings today.
Associated with Obon holiday
According to the lunar calendar, Obon in Okinawa consists of 3 days: unke (pick up), nakanuhi (middle), ukui (see off). Eisa originally marked the night of welcoming and sending off ancestors.
Who does what on an Eisa team?
An Eisa team (usually led by seinenkai — the village's youth association under ~25 years old) is a multi-layered performance machine, each role has a clear function.
Jikata (地方)
Sanshin player and folk singer — the real "conductor", keeping the rhythm for the whole team. Usually undertaken by experienced former members.
Taiko odori — drum dance
Men play big drums odaiko, medium drum shime-daiko and hand drums paranku, combining strong movements (sometimes mixed with karate).
Teodori — waving hands
Usually performed by women, the hand movements are graceful and soft, contrasting with the pounding drum group.
Chondara / Sanaja
The clown dresses up and stirs up the audience with humorous gestures and whistles, while keeping the formation orderly. Usually played by experienced people.
Hatagashira — holding the flag
The bearer of the association's large flag, each village with its own design — a symbol of honor leads the procession.
Costume
Each team has a unique colorful outfit, headband, and belt; Colors and patterns express community identity.
From village ceremonies to stages of 300,000 spectators
The 20th century transformed Eisa drastically. The turning point was the year 1956, when the city of Koza (now Okinawa City) held an island-wide Eisa competition to revive community spirit during the depression — bringing a "performance" element to the choreography, lineup, and music.
1956 · All-island Eisa contest
Koza initiated the "Zento Eisa Competition", adding entertainment and competition to an otherwise purely spiritual ritual.
After World War II · Creativity exploded
Youth associations created their own style: colorful costumes, added songs, developed the teodori and added taiko drums.
1977 · Renamed & expanded
The festival, which bears its current name (Okinawa Zento Eisa Matsuri), gradually became the largest event in Okinawa.
Today · "Creative Eisa"
Creative Eisa appears (modern music, new choreography); Eisa performs at weddings, events, and abroad.
Typical stages
| Events | Characteristics | Scale |
|---|---|---|
| Okinawa Zento Eisa Matsuri Okinawa City, late August/early September | The biggest Eisa festival; 3 days, ending with kachashi and fireworks. | ~300,000 guests |
| Michijune (Michi Junee) | Parade on the streets of residential areas — the most original, intimate form. | Traditional |
| 10,000 Eisa Dancers Parade Naha, Kokusai Street | Grand parade of tens of thousands of dancers on the main avenue. | Mass |
| Eisa Nights Okinawa City, June–August | Weekly performance nights, many teams include children. | Regularly |
When Sanshin leads Eisa
The relationship between these two symbols is the relationship between melody and movement. Understanding this is understanding why Okinawans always say them together.
What does Sanshin give Eisa?
- Melody & lyrics: jikata singing folk songs leads the emotions of the performance.
- Background rhythm: The Sanshin beat is the "clock" for the drum line and dancers.
- Linguistic identity: The lyrics are in Okinawan (Uchinaguchi) preserving the mother tongue.
What does Eisa give Sanshin?
- Community theater: bring the music to hundreds of thousands of people.
- Young generation vitality: Young men learn Sanshin to serve the village's Eisa team.
- Vivid background: Turn living room music into a street festival.
The sound of drums crosses the ocean
Since 1900, Okinawans migrated to Hawaii, Brazil, Peru... bringing Sanshin and Eisa with them as identity baggage. In a faraway place, they become a way of affirming identity Uchinanchu separate from mainland Japanese.
Hawaii
The Okinawa community is large with the Hawaii Okinawa Center and associations kenjinkai, the Eisa team and the Okinawan Festival — where Sanshin and paranku drums still sound.
Brazil
Groups such as Kariyushi Eisá Daiko (Campo Grande, 2002) maintained by the Nisei/Sansei generation, preserve Okinawan heritage in the heart of South America.
Peru
Many Okinawan families in Lima keep koto, Sanshin in their homes; Eisa becomes a bridge for the young generation to find their roots.
Keep pace for the future
Although lively, both Sanshin and Eisa face the pressures of modernity — from materials and craftsmanship to the continuation of the younger generation.
Raw materials & CITES laws
Python skin is difficult to export, kuruchi ebony wood is scarce — pushing up the price of high-quality guitars and promoting alternative materials.
Craftsmanship is lost
The number of Sanshin artisans decreased; Vocational knowledge is at risk of being disrupted if it is not recorded and digitized.
Continuity of young people
Migration for work and urban lifestyles make it more difficult to maintain youth associations in some villages.
Technology & education
Digitalization project (Yamaha), Sanshin class, kunkunshi writing software, "creative Eisa" and experiential travel help pass the fire to the new generation.
