Japan Civil Court Translation Standards for Foreign Evidence
If you are filing foreign-language evidence in a Japanese civil case, the key issue is not whether you bought an immigration-style certified translation. It is whether the court has a usable Japanese translation attached, whether partial translation is enough, and whether the original and translation can be matched exhibit by exhibit. This guide explains Rule 138, partial versus full translation, evidence explanation sheets, electronic evidence, common filing mistakes, public help paths, and how to compare translation providers without confusing marketing claims with court requirements.
