The commission/court order issued by a U.S. court must be sent directly to the U.S. Embassy in Tokyo or the appropriate U.S. Consulate in order to schedule for a deposition to be taken.
The Embassy of Japan reserves the right to request additional documents if deemed necessary.
The Embassy of Japan will not make copies. If you need original documents, please bring the original and one copy.
All applications must be referred to our Home Government for an approval. This may take anywhere from two to four weeks. Please allow sufficient time before your travel date to apply for your visa.
