This is an official document called a "Iki" that records the conferment of the rank of "Jurokui" (Junior Sixth Rank) to the deceased. It belonged to my grandfather, who was the fire station chief. Details: This document was issued based on Japan's rank system when conferring a rank to the deceased according to their achievements and position. The document states "Conferred the rank of Jurokui," and the name and seal of Shinzo Abe, who was the Prime Minister at the time, can be confirmed. *The envelope is also from that time.
