Keep updated on the beauty of Japan!


Its unique motions and sounds give you a blissful moment

GRAVIMORPH is a coined word combining two words : gravitation and morphology. It means "a substance that moves by gravity". When the combination (or encounter) of two simplified structures was affected by the power, it creates simple and unique movements and comfortable tones. Touch, feel and enjoy the beautiful motion and sound.

In August 2019, the product won the "destination: new" award at the trade fair NY NOW summer 2019 held in New York, USA.

A spindle-shaped ball was rolling down the slope with two walls on its either side, which gave birth to the concept of the piece. The ball goes down the slope little by little, hitting the walls and playing beautiful music.

A bead of a Japanese abacus rolling down contiguous bars of equal thickness, which gave birth to the concept of the piece. The bead with two hands waddles and moves down the bars little by little.

Morphology here is the study on the form and movements of objects. It views the shape and motion of things not only as numerical values, but also as phenomena.
