I also found this bit [1]. So there really seems to be a connection between Sukiya-zukuri and Bauhaus:
> In 1954 Walter Gropius, founder of the Bauhaus visited Katsura Detached Palace and was so struck by it that in 1960 he co-authored Katsura: Tradition and Creation Japanese Architecture with Kenzo Tange.
(Though the book quote in the article seems to be about Zen gardens, which reads to me as maximally un-Bauhaus-like, so not sure if the style really was a direct inspiration for Bauhaus.)
