  Yes, some text is written in such manner. But it is rare case.

  Currently, most articles writte in Japanese is L-to-R (horizontal)
or T-to-B (vertical).

  R-to-L is used as

   * Signage (at Temples, shirnes, etc.)
   * Horizontal banner (in early 1900's or older era)
   * Company name written in right side of vehicles
   * Title of some type of articles

and in each cases, only one or a few lines are appeared. Long
sentenses or articles are written in T-to-B or L-to-R.

  I think Japanese is originally written in T-to-B (vertical) only,
and R-to-L can be "considered as vertical writting with columns of one
char length".

  p.s. 
    According to Omega 1.10 (multilingual TeX) announcement in Unicode
    ML that I read in unicode ML, it supports 32 writing directions.
