Japanese Ring Size Guide
NIWAKA jewelry uses Japanese ring sizes. A ring size comparison chart and a Ring Sizing Kit are available to help you determine your Japanese ring size. Most of our ring designs can also be resized after delivery; see Resizing for more information.
Japanese Ring Size Chart
The chart below shows the corresponding measurements for ring sizes on the Japanese and the US scale. If you know your US ring size or ring measurements in millimeters or inches, you can use that information to determine the nearest Japanese ring size. Click the “View Full Chart” button to see Japanese rings sizes 1-30. You can also use the Ring Sizing Kit to get a feel of each Japanese ring size on your finger.
Ring Sizing Kit
Ring Sizing Kits can be purchased to measure your Japanese ring size. This kit measures sizes 1-30 on the Japanese scale in one-size increments. Our rings are available in 0.5- or one-size increments depending on the design, and we recommend using the Ring Sizing Kit to test the fit of each Japanese ring size before ordering.
If you purchase a ring after purchasing a Ring Sizing Kit, the price of the kit will be deducted from the price of the ring.
