Where indicated

The following MUJITSU Shakuhachi by Ken LaCosse are in stock and available for purchase. Feel free to contact me with any questions. I have a number of shakuhachi going in the shop constantly. Many are sold before they make it to this page. If you don't find what you are looking for here I might be working on it now! You can contact me here.

The flutes on this page are the finest that I have available. They are made from Japanese Madake culms of some of the highest quality obtainable. Although each flute has a distinct tonal personality, the overall tonal quality that characterizes Mujitsu Jinashi Shakuhachi is a glowing, fluid playability. The Taimu Shakuhachi are characterized by their breathy, penetrating glow. All flutes are meticulously and patiently adjusted until they are ready to be included here.

The black or dark flutes which are occasionally included here are fashioned after some of the finer vintage Komuso flutes I've had the opportunity to play and study. The Komuso monks often painted the outside of their flutes with urushi, presumably to protect them from the elements. The black urushi surface is soft and velvety yet extremely durable.

Also, check out other shakuhachi for lower priced flutes.

Auditioning Shakuhachi
The Mujitsu Shakuhachi Flutes below can be auditioned under the following terms:

I ask for full payment in advance of shipment (money orders, cashiers checks and PayPal orders only please) Upon receipt of payment, I'll ship the flute by USPS Mail. A full refund (minus shipping expense and Paypal fees - if any) will be given if you decide to return the flute (insured) in its original condition when received. Please let me know within two days upon receipt if you wish to purchase or return the flute.

This auditioning policy does not apply to custom orders or shakuhachi with special requests. These sales are final.

Taimu Fingering Charts

Custom order fingerhole offseting for Taimu Shakuhachi

Pictured above are four hight end Taimu Shakuhachi before the hole drilling stage and root finishing/staining. I've been getting some requests for offsetting from left handed players as well as those who desire other non-conventional hole offsetting. These Taimu have undergone extensive bore work and have excellent node placement and excellent (foghorn ro) resonance typical of the best Taimu. Each is availabe for anyone who desires custom offsetting. Please contact me if you are interested. Other pieces and sizes are available as well.

From top to bottom:

2.83. 86cm in length. A good pick for left hand bottom playing as there is a slight curve to the left near the rootend.  

2.77. 84cm in length. Solid, round, elegant piece of bamboo. Will accommodate any offsetting style.

2.48. 75cm in length. Slightly oval, flattened face for comfortable playing. Elegant, upturned and flared rootend. A very nice, aesthic piece with excellent resonance.
Will accommodate any offsetting style.
$2,500 (Completed and in stock - see below)

2.44. 74cm in length.
Solid, round, elegant piece of bamboo. Will accommodate any offsetting style.

1.8 master concert shakuhachi made by Araki Kodo the 3rd.
This was the main concert shakuhachi of the great Araki Kodo the 4th (Araki Baigyoku) who died at the age of 48 in the early 1940's. It was made by his father Araki 3 in the mid 1920's. After the war the Araki family sold this instrument to a wealthy shakuhachi player and disciple of Inoue Shigemi. Many years after that his son Inoue Shigeshi was able to trade three of his father's best shakuhachi for the "Baigyoku" instrument. Shigeshi Sensei used it as his main concert shakuhachi until his death in the early 2000's. After that, John Singer was able to obtain it and has used it as his main instrument to the present. This is one of the finest concert shakuhachi ever made and was one of the very best that Araki the 3rd ever made. It has two stamps of Baigyoku on each half of the instrument. Extremely rare.

Serious inquiries are welcome.

Mujitsu 2.0 C SOLD One of the best Mujitsu shakuhachi I have available now. And one of the best 2.0's to come out of the shop in years. Powerful, rich, warm, velvety tone. Full ro. Excellent kan response. An exceptional shakuhachi.

Group of five Taimu
Some shakuhachi share a similar voice. These five shakuhachi were harvested in the same batch and share similar characteristics. These are very slightly thinner than conventional Taimu. They are, however, still quite a bit wider than conventional bore shakuhachi. The result is a very well balanced flute throughout. Easy playing higher octaves, yet with a rich, booming, complex Taimu tone.

2.35 Taimu A  SOLD

Dense and solid. Rich, penetrating, foghorn tone. Small, hairline cracks at the middsection. Repaired, bound and stabalized.

2.05 Taimu 

A rich, powerful foghorn Taimu. Very nice traditional aesthetic. Round bamboo, upturned rootend, even, seven node spacing. Taimu at this length are difficult to pull off. This particular piece is at the pinnacle of aspect ratio which (for shorter Taimu) is critical for tone quality and upper register tuning and playability. An exceptional player with traditional Japananese visual aesthetic.

Mujitsu 1.9  (C#)
Here is a 1.9 which somehow defies the odds. It’s made from Chinese root bamboo, but has made it to my high end shakuhachi page.  It has what I call offset hole spacing. (A node between holse 1 and 2 and between 3 and 4) Never the less,  this particular piece turned out to be a gem. In fact, this flute is the best conventional bore shakuhachi to come out of the shop in awhile. This has been my personal shakuhachi for the last year. Originally not for sale. Now available. Rich, warm, resonant, velvet tone. Deep depth. Red urushi bore. Black rubbed urushi velvet like exterior.
