Please look at this sword, I would love to know what it says. The story behind the sword is my father was born in 1951 in Japan. My grandfather was station there after the war. They hired a Japanese nanny to look after my father. After a few years it was time to come back to the states and the nanny gave the sword to my father since she had no kids of her own. I know nothing about it and would love to learn. Thanks in advance for any information. https://imgur.com/a/ku2PDj8
