There are generally small kanji on a japanese calligraphy (shodo) work.
Sometimes they are written above an inkan or inkan set. What are these kanji
for? What types of information is written like this conventionally? Is this a
necessary part of a shodo work? I think they contain some meta information
about the work but I'm not sure.
