She may be a Silver Ginger OEGB: https://secuservices.com/ideal/newideal/selectproduct.aspx?qty=1&ID=SGOEB&Product=1098
Her color doesn't match any Japanese varieties that I could find. Something important to remember about Japanese bantams is that they can have long legs. The short-legged gene is the dominant autosomal lethal creeper gene (Cp), which means chicks that are homozygous for short legs (CpCp) will die in their shells before they can hatch. So a short-legged Japanese bantam is heterozygous (Cpcp) and when bred to another short-legged Japanese bantam you will get 25% dead due to the lethal combination (CpCp), 50% short-legged chicks (Cpcp), and 25% long-legged chicks (cpcp).
