Japanese ring size for engagement rings and wedding bands

Because our rings are all made-to-order, we make your rings with the optimum ring sizes for you.
We do not use commercially available ring gauges. We have exclusive ring gauges between “1.0 to 30.0 in JPN size” to match our ring designs.
Bridal rings are usually made in units of 0.5 ring size, but we can adjust your ring size more precisely. Ring size changes day by day and season by season because of your body conditions and temperature. We are able to make a little adjustment on your ring size at the “fitting.”

Ring sizes may change depending on the season; swelling during the summer and dryness during the winter.
Our recommended ring size is also different depending on the finger shape, just like thick finger joint and thin fingertip.
Because we own our atelier and make rings one by one, we are able to complete the best ring that fits your finger and your lifestyle.

How to choose ring size for engagement rings

We check your ring size with our original ring gauges.
Because the stones stand out very well in the most of the engagement ring designs, the ring can move easily even if it is a little bit loose. We recommend you choose the size which fits your finger as perfectly as possible not to let it move.

How to choose ring size for wedding rings

We check your ring size with our original ring gauges just like engagement rings.
We ask you to open and hold your hand which you wear the gauge on to confirm you do not feel any pressure on your finger.
Because we have a wide selection on the wedding ring designs from thin designs to wide designs, we will check your ring size according to the ring width you have chosen.
