Japanese Yunomi signed in Black Characters Identification please?

Hello and thanks in advance for any information on these 2 tea cups. They are signed in black on the underside and have flowers painted on the exterior and interior. Can anyone help to identify the maker please? Thanks

I think if you go through the labels section on the following site you would find it. It would take a bit of time.
If someone else narrows it down a bit, perhaps reading Japanese, then that would be faster. If nobody is able to a couple hours on this site would likely find it and you would see other things besides....

Thank you for providing the link. Interesting site. I will keep looking. I have 2 so may just put one on ebay and see if anyone recognises it. It is very well made, kind regards C.

They would have been originally sold as a pair. It's very sexist but the larger one was for the gentleman and the smaller one for the lady.

The yunomis aren't in any distinct style but done to appeal to the younger buyer.

The signatures are stylised kanji but, as with signatures in English, they are never easy to read.
