Is Japanese used so often in this field?

Hi everyone. I’m just a newbie to data field and eatery to explore more about the opportunities. Not to mention the fundamental knowledge of data, as I own a decent English proficiency and learning Japanese at high level, It would be lovely if I could use Japanese in this field and have a batter income if possible. If anyone know anything or some helpful information, it would be great for me and anyone who is curious. I’m staying in Asia by the way. Appreciate any replies ^{^}
