Thank you.
How do I change that in my setup?
My setup is creating the same stuff in different languages from XML 
input (LMTX using lua and METAPOST), which means I need to adapt the 
following setup (cyrillic and greek shown as the other languages with 
different character sets I use)
\startmode[JA]
\setuplanguage[ja][patterns={ja}]\mainlanguage[ja]
\stopmode
When your document prints only text in a single language change the 
setup above to

     \startmode [JA]
         \setscript [nihongo]
         \mainlanguage [ja]
     \stopmode

but for documents which use multiple script/languages at the same time 
replace the previous setup with

     \startsetups [japanese]
         \setscript [nihongo]
     \stopsetups

     \setuplanguage [ja] [setups=japanese]

and add \language[ja] before japanese text to ensure linebreaking is 
enabled.
