I wonder if you know why there is no 'ja_jp' language node under /libs/wcm/core/resources/languages, though ja node refers to language code "ja_jp" through the property defaultCountry.
Shall I add ja_jp node then?
Thanks in advance
There is a support for JA and I think ja_jp is not required when ja is supported. it is same as ja_jp.
Node path is /libs/wcm/core/resources/languages/ja
