Thanks for your answers.
I collect (like) Japanese things I have some bronzes, Woodblock prints
a couple of tansu, some Buddha's, tsuba's, porcelain and a couple of swords.
I have not much knowledge about nihonto.
By the way this one is signed
is it possible to narrow the search which Tadamitsu
this could be.
I know it's difficult without a visible hamon or boshi.
