Few people have ever experienced the sound of the kokyu performed live.
Fewer still have had the chance to hold one themselves.
In this article, we answer the question, "What Is the Kokyu Instrument?" We also explore why this 400-year-old instrument became the emotional voice of SHOGUN and where you can experience it for yourself in Tokyo.

What Is the Kokyu Instrument?
The kokyu is Japan's only traditional bowed string instrument — and one of the least known instruments in the world, even within Japan itself.
I first encountered Daisuke Kiba's kokyu in Kagurazaka — the neighborhood where I have lived for over two decades — when he performed at Akagi Shrine as part of the Kagurazaka Street Stage O-edo Tour. His sound stopped me in my tracks. There is a quality to the kokyu — a sustained, melancholic voice that seems to carry the weight of centuries — that I had never heard in any other instrument. From that moment, I became determined to share it with as many people as possible.
While the shamisen and koto are familiar to many international visitors, the kokyu remains largely hidden from the world. Yet its sound is immediately arresting: a sustained, flowing tone that seems to draw a line through the air, rather than the brief, plucked notes of its better-known counterparts.
Structurally, the kokyu resembles the shamisen in its basic form — a long neck, a small resonating body, and three strings. Like the shamisen, its strings are made of silk. But unlike the shamisen, which is struck with a plectrum, the kokyu is played with a bow strung with horsehair. This single difference transforms its voice entirely. Where the shamisen speaks in points, the kokyu speaks in phrases.
The bow of the kokyu is strung loosely — and this is no accident. The slack in the horsehair allows the player to draw across two strings simultaneously, producing the rich overtones that give the kokyu its layered, almost vocal quality. This technique, known as awase-yumi, sets the kokyu apart from most other bowed instruments in the world, where the bow hair is kept taut and contact with a single string at a time is the norm.
The instrument is held vertically on the knee and rotated to change strings — a technique unique among Japanese instruments, and one that demands years of dedicated practice to master.
Its tonal range moves fluidly between soulful melancholy and taut, almost eerie suspense. It can sound ancient and intimate at the same time. Once heard in person, it is not easily forgotten.
Why Is the Kokyu Instrument So Rare?
The kokyu's rarity is not accidental. It is the result of history.
During the Edo period (1603–1868), the kokyu flourished as part of the sankyoku ensemble — a trio of shamisen, koto, and kokyu that defined the refined musical culture of the shogunate era. Performed in the private rooms of wealthy merchants and samurai households, this ensemble was the sound of Edo sophistication.
The instrument's development was driven largely by the Todo-za — a guild of blind musicians who elevated the kokyu from street performance into a refined art form. For these musicians, the kokyu was not merely entertainment. It was a vehicle for emotional expression and, in many cases, spiritual consolation.
Then, in the early twentieth century, the shakuhachi — a bamboo flute — gradually replaced the kokyu in the sankyoku ensemble. Without its primary ensemble role, the kokyu lost its institutional base. Training became harder to find. Masters became rarer. The number of professional players dwindled to a handful.
Today, the kokyu occupies a paradoxical position: celebrated as a cultural treasure, yet heard by almost no one. There are perhaps only a few dozen professional kokyu players remaining in Japan. Of those, only a small number perform at the highest level.
This is why any opportunity to hear the kokyu live — let alone to hold one and play it — is genuinely extraordinary.
The Sound of the Kokyu Instrument
To understand why the kokyu is so emotionally powerful, it helps to understand what makes its sound physically distinctive.
Unlike the shamisen or koto, whose notes decay almost immediately after being struck or plucked, the kokyu produces a sustained tone — continuous, unbroken, alive. This is the nature of all bowed instruments: the bow keeps the string in motion, and the sound continues for as long as the bow moves.
But the kokyu has an additional sonic characteristic that sets it apart even from other bowed instruments: a technique called awase-yumi, or combined bowing, in which two adjacent strings are played simultaneously. This produces rich overtones — harmonics that resonate above the primary note, creating a layered, almost vocal quality. Scholars have compared these overtones to the sound of the shō, the mouth organ used in Imperial Court music (gagaku) — one of the most ancient and sacred sounds in Japanese musical tradition.
The result is an instrument that sounds, to many first-time listeners, like something between a cello and a human voice. It carries grief and grace in equal measure. It can fill a room with stillness.
This is the sound that defined the emotional landscape of Edo-period Japan — and the sound that, centuries later, would find its way into one of the most celebrated television dramas in the world.
How Does the Kokyu Differ from the Chinese Erhu?
Many visitors who encounter the kokyu for the first time notice a resemblance to the Chinese erhu — another bowed string instrument from East Asia. The comparison is understandable: both instruments are played with a bow, both produce a sustained tone, and both occupy a similar emotional register.
But the differences are significant.
The erhu has two strings — today typically made of steel — and is played with a bow whose hair is permanently threaded between the two strings, making the bow and instrument inseparable. The kokyu, by contrast, has three strings and is played with a separate bow. Rather than moving the bow between strings, the player rotates the instrument itself on the knee to change strings — a technique unique to Japan and one that demands considerable skill to master.
Perhaps most importantly, the kokyu developed entirely independently within Japan — shaped by the Todo-za guild, refined through the sankyoku ensemble, and embedded in a cultural context quite distinct from its Chinese counterpart. Where the erhu has remained central to Chinese traditional music, the kokyu gradually retreated from mainstream Japanese music — making it, today, far rarer and more difficult to encounter.
From SHOGUN to Kabuki: Why the Kokyu Instrument Still Moves Audiences Today
The SHOGUN Soundtrack
In 2024, the Hollywood drama SHOGUN won 18 Emmy Awards — the most ever won by a single season of television. Its soundtrack, widely praised for its authenticity and emotional depth, featured the kokyu prominently.
Tracks such as "The Pull of Death" and "All Men Can Be Broken" used the kokyu's sustained, haunting tone to give emotional weight to some of the series' most pivotal scenes. For many international viewers, it was the first time they had ever heard the instrument — even if they did not yet know its name.
The global success of SHOGUN has created genuine curiosity about Edo-period culture among travelers worldwide. The kokyu is now part of that story.
Kabuki: The Role of Akoya
Within Japan, the kokyu holds a place of extraordinary prestige in the world of kabuki theatre.
In the classic kabuki play Dan-no-Ura Kabuto Gunki, there is a scene known as Akoya — considered one of the most technically demanding and beautiful scenes in all of kabuki. In it, the courtesan Akoya is required to play the koto, shamisen, and kokyu live on stage, one after another, to prove her innocence. The assumption is that a guilty person could not play with such purity and concentration.
The kokyu section — a piece called Tsuru no Sugomori — is the climactic moment. It demands not only technical mastery of the instrument, but the ability to convey, through music alone, the inner emotional life of a woman concealing her love and her grief.
Today, it is said that only one performer in Japan can play Akoya at the highest level: the legendary onnagata actor Bando Tamasaburo V, designated a Living National Treasure by the Japanese government in 2012. The reason so few can perform the role is, in large part, the extreme difficulty of playing the kokyu.
This is not a historical curiosity. It is a living testament to how demanding this instrument truly is — and why those who have mastered it command such deep respect.
Owara Kaze no Bon: The Festival Where the Kokyu Instrument Still Reigns
Every year, Daisuke Kiba — one of Japan's foremost kokyu masters — travels to the mountain town of Yatsuo in Toyama Prefecture to perform at one of Japan's most atmospheric festivals: Owara Kaze no Bon.
He is not there as a guest. He is there as a keeper of the tradition.
For three nights, from September 1 to 3, dancers in woven hats move slowly through the lamplit streets while shamisen and kokyu players provide the music. The kokyu's melancholy tone is inseparable from the festival's identity — a sound that seems to belong to the mountains, the autumn air, and the passage of time.
This 300-year-old festival remains one of the very few occasions in Japan where the kokyu can be heard in its natural context — performed outdoors, at night, in a setting that has changed little for centuries. To hear the kokyu at Owara Kaze no Bon is to understand, in a way that no recording can convey, why this instrument has endured for 400 years.
2026 festival dates: September 1 (Tuesday) to September 3 (Thursday)
September 1–2: 17:00–23:00 | September 3: 19:00–23:00
For those who cannot travel to Toyama this autumn — or who wish to go beyond listening, to actually hold and play the instrument themselves — there is another way to encounter Daisuke Kiba and the kokyu he has devoted his life to.
That encounter takes place in Tokyo.

Meet Daisuke Kiba — Japan's Foremost Kokyu Instrument Performer
Daisuke Kiba's path to becoming one of Japan's foremost kokyu masters began with rigorous classical training — music theory at Koyo Conservatory of Music, followed by years of study under the renowned master Kazuo Hara. But what distinguishes him is not only his technical command of the instrument. It is the breadth of the world he has carried the kokyu into.
His performances have taken him from the stage of the National Theatre of Japan — where he has appeared as a regular performer — to the concert halls of Tokyo, where his solo recitals at Kioi Hall have earned critical acclaim. The Agency for Cultural Affairs Arts Festival has recognised his artistry. NHK and NHK World have broadcast his performances to audiences across Japan and beyond.
Then came Hollywood. When the production team behind the Emmy Award-winning drama SHOGUN sought an authentic kokyu voice for the soundtrack, they turned to Kiba. His contribution to tracks including "The Pull of Death" and "All Men Can Be Broken" brought the sound of Edo-period Japan to a global audience of millions.
And then, in a pairing that speaks to his remarkable range, he appeared as a guest artist in concerts by Grammy Award-winning singer Alicia Keys — demonstrating that the kokyu, in the right hands, speaks a language that transcends cultural boundaries.
Through it all, he returns every September to the mountain town of Yatsuo in Toyama, to perform at Owara Kaze no Bon — grounding his global career in the living tradition from which it grew.
He has also pushed the instrument's boundaries in more literal ways: pioneering the development of a four-string kokyu with an extended lower register, and actively composing new works to expand the repertoire available to future players.
Daisuke Kiba is, in short, exactly the kind of artist you do not expect to meet. And in Kagurazaka, Tokyo, you can.

Why Experiencing the Kokyu Instrument Live Is Different from Listening Online
In Tokyo's Kagurazaka, the kokyu is performed just one or two metres in front of you. But what exactly changes when you hear it live — rather than through a screen or a recording?
Here is what changes when the kokyu is performed in the same room as you:
The physical presence of the sound. Bowed instruments produce overtones that recorded audio compresses and flattens. In person, the kokyu's harmonics fill the space around you. You feel the sound as much as you hear it — the vibrations passing through the air and into your body, in a way that no recording can replicate.
The intimacy of the performance. In a small private setting — a traditional tatami room, a quiet cultural space — the performer is perhaps one or two metres away. You can see the movement of the bow, the placement of the fingers, the subtle shifts in the player's posture that produce changes in tone. This is not a concert. It is a conversation.
The opportunity to ask. In a private session, you can speak directly with Daisuke Kiba: about the instrument's history, about its role in SHOGUN, about the techniques he has spent decades developing. This kind of direct dialogue with a world-class musician is almost never available to the general public.
And it is a conversation with a great deal of history behind it.
Among the pieces Daisuke Kiba performs is Tsuru no Sugomori — the very kokyu composition at the heart of the kabuki scene of Akoya, which we described earlier in this article. In conversation with Kiba himself, he shared a historical account that does not appear in any written record: when the eighth shogun, Tokugawa Yoshimune, once listened to Tsuru no Sugomori within the walls of Edo Castle, real cranes were said to have taken flight at the sound of the music.
This story has been passed down quietly among kokyu players — a rare fragment of living oral tradition, not found in books or online. We share it here, as Kiba shared it with us, in the hope that it conveys something of what this instrument is truly capable of.
That cranes would rise at the sound of a bow drawn across three silk strings — this is not simply a charming legend. It is a measure of what it means to master the kokyu. And it is the standard to which Daisuke Kiba holds himself, every time he performs.
The chance to hold and play the instrument yourself. Under Daisuke Kiba's guidance, you will hold the kokyu — a cultural tradition spanning 400 years, placed directly in your hands — and draw the bow across its strings. The sound you produce will be imperfect at first. But within a few minutes, something remarkable happens: a clear tone begins to emerge. That moment of discovery — when the instrument begins to respond to your touch — is one of the kokyu's most surprising qualities.
I know this from personal experience. I once attended one of Daisuke Kiba's kokyu lessons myself. Within a single 90-minute session, I was able to play a simple piece from beginning to end. For an instrument that looks so demanding from the outside, this was something I had not expected — and it made me want to share the experience with as many people as possible.
Experiences like this are almost impossible to find anywhere in the world. That is precisely what makes this encounter so extraordinary — and why those who have experienced it consistently describe it as one of the most memorable moments of their time in Japan.
Where to Experience the Kokyu Instrument in Tokyo
There are very few places in the world where you can hear the kokyu performed live. There is currently only one place where you can hear it performed by a master, in a private setting, and then play it yourself.
That place is Kagurazaka, Tokyo — and the experience is offered by EDO KAGURA.
But why Kagurazaka? The answer goes deeper than geography.
It was here, at the Kagurazaka Street Stage O-edo Tour, that I first heard Daisuke Kiba perform the kokyu — and felt compelled to share that experience with the world. But Kagurazaka's connection to the kokyu, and to the broader world of traditional Japanese music, runs far deeper than my own encounter.
Kagurazaka is one of Tokyo's great music neighborhoods. It was home to Michio Miyagi — one of Japan's most celebrated koto masters, and one of the most internationally recognized Japanese musicians of the twentieth century. His composition Haru no Umi ("The Sea in Spring") was released on record in Japan, the United States, and France in 1932, bringing traditional Japanese music to global audiences for the first time. Today, Haru no Umi remains one of the most beloved pieces in Japan — broadcast every New Year across television and radio, familiar to virtually every Japanese person alive.
Miyagi was blind. Like the masters of the Todo-za — the guild of blind musicians who elevated the kokyu into a refined art form during the Edo period — he transformed limitation into extraordinary artistic achievement. His former residence in Kagurazaka is now the Miyagi Michio Museum: the first museum in Japan dedicated to a single musician.
The museum is currently undergoing renovation and is expected to reopen in spring 2027. When it does, it will once again stand as a testament to the extraordinary musical legacy that took root in these streets — and continues to live here today.
The instruments of the sankyoku ensemble — koto, shamisen, and kokyu — have deep roots in this neighborhood. And it is in this neighborhood that you can still encounter them today, performed live, in the hands of a living master.
The SHOGUN Cultural Experience is a fully private, approximately three-hour cultural journey through one of Tokyo's most historically significant neighborhoods. It brings together three encounters in a single, carefully composed journey:
A guided walk through the streets of Kagurazaka — shaped by the Tokugawa shogunate over 400 years ago
A wagashi workshop and tea ceremony led by Takeshi Inoue, a certified Tokyo Meister and supplier to the Imperial Household
A live kokyu performance and hands-on session with Daisuke Kiba
The experience is available as a fully private booking — exclusively for your group, with no other guests. It is conducted in English, Spanish, and Japanese.
For travelers who have watched SHOGUN and wished they could step inside its world — this is as close as it gets.
More than a concert. More than a workshop. It is a rare opportunity to step into a 400-year-old musical tradition with one of the people keeping it alive today.

About the Author
Shinya Yamada is the founder and Representative Director of EDO KAGURA, a cultural experience company based in Kagurazaka, Tokyo — a neighborhood he has called home
for over 25 years.
His connection to the kokyu is personal. He has taken kokyu lessons directly from Daisuke Kiba, and within a single 90-minute session, was able to play a simple piece from beginning to end. That experience convinced him that the kokyu — despite its reputation for difficulty — is an instrument that can move anyone willing to encounter it.
Kagurazaka, where Yamada lives and works, is itself deeply woven into the history of Japanese traditional music. The Michio Miyagi Memorial Museum — dedicated to one of Japan's greatest koto masters, whose composition Haru no Umi brought traditional Japanese music to global audiences — stands just minutes from his door. The instruments of the sankyoku ensemble: koto, shamisen, and kokyu, are not distant history here. They are part of the neighborhood's living identity.
Through EDO KAGURA, Yamada has made it his mission to bring these traditions within reach of international visitors — not as performances to watch from a distance, but as experiences to feel firsthand.
