Here is my code. this code works on Nexus9.(Locale is Japan)

public class MainActivity extends AppCompatActivity{

    static final String TAG = "TTS";
    TextToSpeech mTts;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        final String emailid;
        emailid = "こんにちは";

        mTts = new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {
            @Override
            public void onInit(int status) {
                if (status == TextToSpeech.SUCCESS) {
                    int result = mTts.setLanguage(Locale.JAPAN);
                    if (result == TextToSpeech.LANG_MISSING_DATA
                            || result == TextToSpeech.LANG_NOT_SUPPORTED) {
                        Toast.makeText(getApplicationContext(), "This language is not supported", Toast.LENGTH_SHORT).show();
                    }
                    else{
                        Log.v("TTS","onInit succeeded");
                        speak(emailid);
                    }
                } else {
                    Toast.makeText(getApplicationContext(), "Initialization failed", Toast.LENGTH_SHORT).show();
                }

            }
        });
        setVolumeControlStream(AudioManager.STREAM_MUSIC);
    }

    void speak(String s){
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            Log.v(TAG, "Speak new API");
            Bundle bundle = new Bundle();
            bundle.putInt(TextToSpeech.Engine.KEY_PARAM_STREAM, AudioManager.STREAM_MUSIC);
            mTts.speak(s, TextToSpeech.QUEUE_FLUSH, bundle, null);
        } else {
            Log.v(TAG, "Speak old API");
            HashMap<String, String> param = new HashMap<>();
            param.put(TextToSpeech.Engine.KEY_PARAM_STREAM, String.valueOf(AudioManager.STREAM_MUSIC));
            mTts.speak(s, TextToSpeech.QUEUE_FLUSH, param);
        }
    }
    @Override
    protected void onDestroy() {
        super.onDestroy();
        // Don't forget to shutdown tts!
        if (mTts != null) {
            Log.v(TAG,"onDestroy: shutdown TTS");
            mTts.stop();
            mTts.shutdown();
        }
    }
}
