Hi Ken, Mark beat me to it as I was typing. The signature appears to be: "Hi-Shu Ju Tada-Yuki". (the second kanji is poorly written, but I can't imagine any thing but Shu.) Hishu can refer to either Hizen or Higo province. There were a few Tadayuki from Hizen/Higo that worked in the mid to late 1600. Would need an overall photo and more detail to give you more than that.

Thank you for that translation. I will send more photos.

I can take more, if you guide me on how to take the photo. Again thanks

Hi Ken,

Sorry, I'm not going to be able to tell you too much about your sword, but lets start with what we can see. The sword is a real Japanese sword called a wakizashi, traditionally a sword between 12 and 24 inches. For Samurai it was a companion sword carried along with a long sword (katana). Merchants and non-samurai could carry a sword of this length, but not a katana. The sword was carried edge up inserted through an obi. I'm guessing it is a Shinto period sword. That is, a sword made between 1596 and circa 1780. The condition of the polish is not good, so no details of the grain or hamon can be seen to help us evaluate it. Hawley lists only four Tadayuki working in Higo or Hizen, all between 1661 and 1845. 

Perhaps one of our better sword evaluators will weigh in, and can provide a better appraisal for you.

Hope this helps, Tom
