Hamri is a wedding and engagement ring specialist located in Omotesando, Tokyo, offering couples a personal way to create rings and lasting memories. At its seasonally decorated studio, customers can make their own rings or choose a fully bespoke design, with both options offered at the same price. In hands-on workshops, couples shape a wax model themselves; experienced craftspeople then cast and finish the ring.

Customers can also entrust the entire design and production process to Hamri. Courses include wedding rings, engagement rings, and matching three-ring sets, alongside proposal rings, diamond proposals, and remodelling services for inherited diamonds. Designs can be customized with a choice of precious metals, birthstones, settings, surface finishes, and engravings.

Hamri also provides free design consultations and estimates, and shares a collection of more than 3,000 customer-made designs for inspiration. During handmade ring sessions, the studio photographs and films the making process and gives customers all the image and video data, preserving the experience as part of their story
