Solo progressive rock project of Yoh Ohyama.

Asturias was originally formed by Ohyama in 1987 as a multitrack recording group with Haruhiko Tsuda (guitar), Akira Hanamoto (keyboards), and Kazumi Sakurai (drums), with Yoko Ueno as a guest vocalist. After releasing CRYPTOGAM ILLUSION in 1993, they disbanded, and Ohyama would later rename and refocus the group as Acoustic Asturias in 2003. In 2008, he began releasing music under the name Asturias again with no dedicated members besides himself.
