Help for translation signatur

[kanemoto]

I haven't checked in for a long time, I've been working a lot on my house. Now begins again the time for my hobby, Japanese swords and build Habaki. I got 1 Ko- Wakizashi and a Tanto, both in very bad condition but with good tsuba and sword ornament. Now I need help with the translation of the signatures. The tsuba of the wakizashi could be Yamanaka school. The fuchi from the tanto has a signature from Umetada school. Is this Myo Toshi ? Menuki, tsuba, kurikata, sayayiri all match with dragon. Is the signature real ??? 
Thank you for your help.

Hi Uwe,

The signature on the fuchi is Umetada Myoju:

埋忠明壽

Love the tsuba!

As in the other thread, the tantō is 義弘 Yoshihiro, using a variant of 弘.

Hello to all friends and thanks for your help. 
Of all the parts on the Wakizashi is only the Fuchi signed, are then all parts from the same master?
In any case a good buy.
I think I still make many mistakes on the message board. Computer is not my strong point, I prefer to do Habaki, but I will take care of this site more.
