Unknown Artwork

Good morning,

Have you ever come across a piece of art and have no information about it or if it is worth anything?  Of course, it has nostalgic value because it hung in my parents' home for many, many years.

My digital image above has somewhat more vibrant colors than the original painting, I believe is a watercolor.

Here's a close up of the signature.  Japanese?

The painting was framed by Suder's Art Store in Cincinnati, probably in the 1930's.

Does anyone have any insight into this lovely piece?

Thanks!

Lois
