Help with MON on Japanese sword with ancestral blade

[MilitaryCollect]

Hello,

Can anyone please identify the MON. The blade is a wak and signed "Hoki {no} Kami Fujiwara Nobutaka". The mounts are naval.

Thank you,

Hi!
Is it possible to research a sword with MON, can you find out who had it?

Research of individual soldiers by mon is a total impossibility.By the end of the feudal period, every family in Japan used a mon of some form. The star mon with three bars is not commonly encountered. However, any form of crossing referencing to an individual is impossible.

Hello,

I was told the wak had come from a Japanese admiral. Any information as to the MON would be most appreciated.
