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.


Gravity is the universal gravitation of the earth, which acts upon objects on the planet, causing them to fall toward the ground and to generate mass.


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.

We have developed GRAVIMORPH to bring a unique style from Japan to the world. The goal is to help you look at yourself, improve yourself, and heal your weary mind. It is especially recommended for the people, who are in their 30s and 40s. Amid the hard work you do for your family, society and daily life, we would like you to really cherish the time just for yourself. If you can enrich your own mind, it will be the first step to making everyone around you happy.
