shinkai would like to express the beauty of a pearl highly made by nature and the strength held within a natural stone. They are made in a unique Japanese style, handmade to have a delicate and warm soft texture. We would like to hold refined metalcraft technique and novel concept to resonate with those who wear it. We consider deeply about the material of each pearls and stones individuality. For this reason, we use the uniquely different shapes seen in baroque pearls as the main motif. Our jewelry is simple and elegant. Subtle yet bold. Created by high level technique, and understanding, it is able to have its own unique aesthetic since we are both the designer and the craftsman.

We aim to create jewelry that takes advantage of the individual characteristics of materials born from the blessings of nature, and creates a sense of comfort with the originality and advanced technology cultivated through experience. I want to deliver shinkai to people who enjoy their own senses without being bound by existing values.
The designer uses the advanced techniques he has cultivated as a craftsman and his own aesthetic to create simple, elegant, delicate, and bold jewelry.
