Dear ConTeXt users,

I am trying to write a document (grammar notes) in English and Japanese
and so far have used XeTeX (for Unicode support) with tikZ (for
graphics) quite successfully. However, I wish to convert to (Xe)ConTeXt
in order to have more control over the page design.

At the moment I am stuck at trying to define English and Japanese fonts.
In XeTeX I used

\usepackage[BoldFont]{xeCJK}
\setCJKmainfont{IPAMincho}
\setCJKsansfont{IPAGothic}
\setCJKmonofont{KanjiStrokeOrders}

in order to set the three different Japanese fonts I am using.

I haven't found any documentation on how to implement something
equivalent in ConTeXt and would be most grateful if someone could
outline how I would best go about converting my XeTeX document to ConTeXt.

Many thanks.
Kind regards,
Severin

P.S.: If you think I'm crazy for trying to mix XeTeX, ConTeXt and tikZ,
please tell me now... =) Also, it feels like ConTeXt MkIV with LuaTeX
would be the best choice (if the project were just already beyond the
beta stage), but I don't really know an awful lot about that either. Any
thoughts on how successfully I might be able to implement the above in
LuaTeX would also be much appreciated.

I have attached a page illustrating how I have been using XeTeX and tikZ.
