Hello everyone, today I came across this post by chance. If it violates any rules, please let me know or remove it. The following are my views.
This sword is a fake that appeared on Yahoo Japan a few years ago. First, based on the inscription, the original owner only became the captain of the battleship Yamato in 1944. It is impossible for him to have foreseen this in 1942. Second, I checked some archived websites and found other fake Kikusui swords on Yahoo Japan between 2017 and 2019. They all have a similar style and format. Finally, I am not an expert on Kikusui swords, and there may be some mistakes in my research. Here, I will post the pictures I found and a link to a Japanese blog that questions the authenticity of these swords (the blog does mention a possible original selling link for this sword, but I cannot access it). I welcome any experts to join the discussion. I apologize for any disturbance.
