As I explained in the ConTeXt Meeting, in (nowadays) Japanese vertical writings, they have some amounts of alphabetical words among Japanese characters. In those cases, Japanese characters and short (less than 4 letters) alphabetical words such as acronyms should typeset in RTT, but long alphabetical words in RTR. Moreover, _tate-chu-yoko_ (horizontal-in-vertical settings) could be tricky for some people.
