JAXB: can not read Japanese characters properly

I am having a program which supports internationalisation. I have entries where input is provided in Japanese characters. On exporting that entry in XML, using JAXB, Japanese characters looks fine in the file. Proper character is been exported in the XML file. I am facing issue when unmarshal that XML file to get back data as Java object. I am not get proper unmarshalled value of japanese character.

Here is my marshalling code:

OutputStreamWriter outputWriter = new OutputStreamWriter(new FileOutputStream(file), "UTF-8");
JAXB.marshal(xmlobj, outputWriter);

Unmarshalling code:

InputStreamReader inputReader = new InputStreamReader(xml, "UTF-8");
xmlobj = JAXB.unmarshal(inputReader, <JAVA_CLASS_TO_UNMARSHAL>);

The text I am marshalling-unmarshalling is: 説明_1

It displays correctly on fetching this record and display it to browser, but in case of JAXB unmarshalling incorrect value is displayed. After converting it to HTML compatible code I got value 説明_1, which is actually correct conversion of Japanese characters. And it should appear as proper character on the browser, but it does not do so. It displays as HTML codes 説明_1 to the browser.

Any guess where I am doing wrong?
