Japanese passports from this time right after WWII are nowadays rare to find. They had real leather covers and golden imprint. Truly a representative passport. This document was issued to Master Junichi Sakuma (James W. Markle) on 21 Dec 1956. The boy was just 3 years old and was traveling to the USA for permanent residence. No stamps in passport, which is in excellent condition. A great document for your collection.
