Japanese Teahouses in the U.S.

I am researching Japanese teahouses that were built in Rhode Island - I read a column in the New Yorker by Lewis Mumford (10/2/1954) that discusses the 1954 Japanese House at MoMA, and he mentioned that some American missionaries, upon returning to the United States, built these Japanese-style houses in the late 19th C. Can you help me find more information about this?

The only additional resource that could be found is a reference to a Chinese teahouse built on the estate of a society woman, Alva Belmont, in Newport, RI.

The Newport Historical Society may have additional information about teahouses as well.
