Greetings from Syncfusion.
Currently our Digital gauge supports only numbers (0 to 9), alphabets in English language with upper (A-Z) and lower case (a-z) and some predefined symbols and special characters. It does not support Japanese or any other languages.
Also, we are afraid that we do not have immediate plans to implement this.
