Help With Oriental Glass Triptych

Hello-
Can any of you help me identify what I have here? It's a folding glass triptych set in a hinged metal frame. The glass is cut and painted on the reverse. The subject is cranes. That middle section measures about 13-1/4" by 8-3/4" to give you a sense of its size. The metal (is it copper?) at least has a copper finish. Oriental (are they Japanese?) characters run down the left side of the center panel. Can anyone read them? It was coated with attic grime when acquired. I need help with what I have here-any thoughts will be appreciated.

Google translate is a bit confused, the name is Chinese.
I remember these miniature screens as Chinese souvenirs when I was in Hongkong. They are also used as houseplant screens.

 

Thank you. I'm not the least surprised that Google Translate is confused. Here's what it comes up with when instructed to use Chinese.

Maybe it was a corporate gift.

 

My first thought would be a Chinese or possibly Japanese reverse-painted glass table screen rather than something I’d confidently call Japanese from the photos alone.

The crane, bamboo/foliage and vertical inscription are very typical East Asian decorative motifs, and the hinged three-panel format looks like a miniature folding screen made for display. I’d guess early-to-mid 20th century unless there are construction details that point earlier.

I’d be very careful cleaning it. If the decoration is reverse-painted directly on the glass, I would avoid getting any cleaner or moisture onto the painted side until you know exactly how stable the paint is.

A close-up of the inscription, the hinges, the back of the frame and any marks on the metal would probably help narrow down the country and date quite a bit.

 

Thanks for your thoughts everybody! I cleaned it already. The paint is stable but I was careful.
