EDIT - you have already noted Andrew that you don't believe the following RK is the RK you're asking about. I'll leave the description below anyway cause it strikes me as neat:
In 1925 Riichiro Kawashima became a member of the Kokugakai Club which helped to introduce renowned western painters to Japan by organizing special exhibits every year. [RK then published books on these exhibits]. The artists included Matisse, Rodin, Leach, Rouault, Monet, Renoir, Chagall, Picasso, and Cezanne. These exhibitions not only helped members train themselves, but also contributed to influencing other artists in Japan, who until then had very little chance to see Western paintings.
