''A history of Japanese literature ''by Katoh'

I attended a course of lecture on '' a history of Japanese literature'' by Prof. Youichi Komori at Tokyo University.
It was a fresh summery morining. Most of the audience was the aged ,more than sixties.
When Prof.Komori has entered the class ,an emcee has introduced him to us ,then he started speaking.
It was in my high school days when I encountered his essay ''A warp of the roof in the wooden buildings in China ''.
