Q. What are some resources for studying glass in Japan, brought by the Silk Road?

From Dr. Robert Brill, Research Scientist Emeritus:

Fuji Art Museum.  Shiruku rodo no bijutusu - Arts of the Silk Road. Fujinomiya, Japan: the museum, 1990. 

In Japanese.  Includes glass.

The Grand Exhibition of Silk Road Civilizations was an exhibition held in 3 locations in Nara, Japan. This catalog presents the part of the exhibition held at one of those locations.

The papers of Kazuo Yamasaki of Nagoya University are important in that field.

Dr. Takayasu(sp.?) Koezuka at the Nara National Cultural Properties Research Institute could probably be very helpful.
