Aiming for the soft sound that harmonized with other musical instruments.

W-37 was developed based on the voice of artists, and is a model having different personality from previous keyboard harmonica (we call it "Kenhamo"). Kenhamo is attractive with a tone that has a presence that can not be buried in other instruments. On the other hand W-37 aims at a soft tone that harmonize with other instruments even in music that requires delicate sound expressions such as classical music, musette and jazz.
Taking particular note of wooden characteristic which have an effect of absorbing and suppressing harmonic overtone in high notes, and using wood is decided for cover which is a big factor influencing Kenhamo sound. As a best matched material with reed sound, mahogany is adapted. In combination with the feature of mahogany, thick sound, W-37's sound was born with soft and claiming it's sound firmly.

※ Harmonics overtone is the other tone sounded at the same time when fundamental tone is sounded, and the impression of sound is changed according to the content of harmonics included.
While the more overton is included the tone is brighter and more vibrancy,  the more overtone in high notes it sometimes feel unpleasant tone.

A sense of unity with the instrument for more high expressiveness.

Wooden part of W-37 is all handmade. The warmth of wood is soft, the carefully finished surface make it possible for finger to move smoothly and play comfortably. Beside shoulder strap can be attached enabling more flexible performance. Due to the sense of unity with instrument, focusing on just performance without feeling stress.

Presence and harmony from the beauty of nature

Using Mahogany, beech, the color, gloss and pattern that each has naturally become the beauty of this instrument as it is. While shining it's unique presence, it harmonize beautifully with string instruments such as violin and cello. The rarity of not having the same thing as one is also an attraction of natural materials.


W-37 won the Good Design Award 2017. It received an evaluation for the charm of the wooden finish and the high degree of completion as an musical instrument in pursuit of the tone.
