This form of artistic writing is known as 書道 (shodō), meaning "way of writing". Nice strokes of Cursive Script (sōsho) of an ancient Hiragana, Katakana and Kanji calligraphy artwork. It even includes the Hanko (red stamp of artist's signature) in the bottom! Unfortunatey I was not able to translate this, but it seems to be some kind of poetry from the Han Dinasty.
The spreading ink effect and the red stamp are really nice touches!
