Sure.

You have been writing Japanese with an encoding that doensn't support
it. I bet your default encoding, derived from your operating system
locale (you may see that from System.getProperties() . .. ) is ISO-8859
or something like that. It does not support Japanese.

You should look at OutputStreamWriter, of which you can make an instance
that uses an encoding that supports Japanese. You can get an idea of
what encodings are supported by looking at the CharSet class of java
1.4's nio package. There is a static method there, I forgot its name,
that will return you a Set of the names of supported encodings.

You may end up using ISO-2022-something, but I prefer Unicode's UTF-8,
it's a lot nicer and cleaner, and it supports almost any language. You
will need Unicode fonts though.

En encoding is the mapping from bytes (sequences of 8 bits) to a higher
level of abstraction, namely characters. Streams are byte oriented,
readers/writers are character oriented, and encoding/decoding is in
between.

Hope that helped.
