I try to change widget language follow the document   TreeList / Localization ( ) .

Success in  kendo.messages.en-US.min.js ,kendo.messages.zh-CN.min.js , kendo.messages.zh-TW.min.js ,

but kendo.messages.ja-JP.min.js doesn't work  , it will show english  not  Japanese.

I check network  package  , server   return kendo.messages.ja-JP.min.js  content is correct


Also  the document demo (TreeList / Localization )  have same issue in  kendo.messages.ja-JP.min.js.

Did i miss something or kendo.messages.ja-JP.min.js something wrong.

Kendo UI version :2018.2.620

Hi Ryan,

This behavior is observed because the messages file for the ja-JP culture has missing messages. You can find the non-minified file here:

See that there are no translations for TreeList.prototype.options.messages. Not all messages files are complete and contributions from the community are welcome. You can find more information here: Contribution.

If you need a quick fix, you can copy the command and editable messages from the Grid. To do this, put the following script in the page before creating the TreeList:
  if (kendo.ui.TreeList) {
    kendo.ui.TreeList.prototype.options.messages =
      $.extend(true, kendo.ui.TreeList.prototype.options.messages,{
      "commands": {
        "cancel": "変更のキャンセル",
        "canceledit": "キャンセル",
        "create": "新規レコードを追加",
        "destroy": "削除",
        "edit": "編集",
        "excel": "Export to Excel",
        "pdf": "Export to PDF",
        "save": "変更の保存",
        "select": "選択",
        "update": "更新"
      "editable": {
        "cancelDelete": "キャンセル",
        "confirmation": "このレコードを本当に削除しますか?",
        "confirmDelete": "削除"
