Looking for information on this piece of antique Japanese furniture

[diana]

Hello,
I am a consignment seller, I sell items for other people, mostly on Ebay for commission. I have a client who is looking to get some information and date a piece of furniture she's had for 15 years.

I aksed for all of this information:

Find out the composition of the furniture. What type of wood? Is there marble? Etc. List all materials.
Make a note of any damage, including scratches, dents, chips, cracks, etc.
Take clear, well-lit photographs from all angles.
Search the piece for any labels or maker’s marks. Write them down and take photos.
Look to see if any previous repairs have been made to the piece (like a new screw replacing an old one).
Write down any known provenance of the piece.

Unfortunately she had none of this info and only told me there were no makers marks. I am just hoping to get some information or pointed in the direction of someone who might be able to help me.

Thanks so much and here are some photos.
