The Spirit of Manyoshu: With the Land - Teichiku Literary Cassette Volumes 1 & 2 Commentary and Recitation by Takashi Inukai Includes Autograph Professor Takashi Inukai is a leading expert in Manyoshu studies. This set includes Professor Inukai's commentary and recitation. It contains 10 cassettes and a catalog. My mother received an autograph from Professor Inukai when she purchased this. It has been stored at home, so the cover and catalog show some wear and tear.
