Family Mon on Fuchi/Kashira

[Itomagoi]

Hello,
can someone please help me with this family mon?

It is on the fuchi and kashira. I have looked on the internet and in the book by Hawley & Kei Kaneda, but can't find it.

Thank you for your help.

Best regards

Looks like a tsuta (ivy) mon, this family used it https://en.wikipedia.org/wiki/Matsunaga_clan

Hi Manuel,
yes, i thought of that family, too. But I am unsure and wanted to ask here for more opinions.

Thank you.

I think this is it.

True. Thank you, Piers.

Just found this one on a Type 98 with a Showa-stamped 1940 Yasutsuna blade.  At an auction.
