What kind of jobs can I get with degree plan?

I'm currently an undergraduate student majoring in a B.S. in mathematics, a minor in Computer Science, and in a Japanese Studies Certificate. I already know that a bachelor's degree in mathematics isn't enough to open many doors for opportunities, unless I immediately want to teach it. After graduation, I'm interested in applying for a masters program in Computational Science. I think my current undergraduate study will help me prepare for getting into the program along with the honors, awards, and work experience I have. Now, I'm wondering whether or not that in the end if there are plentiful jobs in the Computational Science field that have a Japanese language background. Though, I have researched that there exists some American Japanese related jobs linked with tech companies. I would really appreciate it if anybody knowledgeable could reply back to me as soon as possible.
