About us



"Monaka" is an archaic word for the mid-autumn full moon.

An eye for gems as decorative items along with a mineralogist's love of fine stones

Inspired by a truly original selection of distinctive precious stones

that are combined with sensitively selected unique materials

and assembled into designs that bring out the inner beauty of the ornaments.

Each individual piece of jewelry is carefully handcrafted to become a treasured personal expression

that will be cherished for years to come.

Started activities at monaka in 2012

Designer: Asako Hojin

Asako studied design and became a goldsmith at Itami College of Jewellery.

After graduating, she left Japan to work as a designer/maker at a fashion accessory studio in Antwerp, Belgium.

She relocated back to Japan to work at a jewelry company based in Kyoto where she was deeply involved in developing iconic products.

Then she moved on to a new career at a department store in Tokyo where she gained experience in designing high-quality jewellery for high-profile clients and buying jewellery from overseas.

This gave her in-depth knowledge of diamonds and precious stones.

In 2012, Asako started her own jewellery brand, monk.
