Medium: Tanaka is best known for his incredibly intricate black and white etchings (sometimes with aquatint or mezzotint), which this print appears to be. He personally printed and edited all of his etchings, and typically destroyed the copperplate after the limited edition was complete.
Subject Matter: His work almost exclusively focuses on the rural Japanese countryside, particularly the traditional thatched-roof farmhouses, old walls, trees, and small-town scenes that were rapidly disappearing during his lifetime.
Style: His prints are celebrated for their hyper-realistic detail and masterful use of line to create rich textures for straw, wood, tile, and stone. His scenes are often quiet, with human presence only implied.
Recognition: His work is widely collected and held in the permanent collections of major institutions, including the Museum of Fine Arts Boston and the Metropolitan Museum of Art.
Signature and Date: You can see the signature and the last two digits of the year in the lower right, likely in pencil, which is characteristic of his work. The year appears to be '05 (2005). The signature is often just "T. Ryohei."
Edition Number: In the lower left, you can clearly see the numbers 34/150. This indicates that your print is the 34th impression out of a total limited edition of 150 prints. This numbering confirms it is an authentic, hand-pulled limited-edition print by the artist.
Title/Catalogue Number: There is an additional marking in the very bottom left corner, ナニワ-し. This is likely a Japanese title or a catalogue/reference number used by the artist or a gallery.
The scene itself, depicting a traditional Japanese house with sliding screens (shoji or similar) and a tree next to a fence or bridge, is a classic subject for Tanaka.
The print's width and height are 11.1" by 11.3"; and the image's width is 7.3" by 7.4".
