Major in English or Foreign Language

Hi guys. I am currently a rising sophomore at a semi-target school looking to go into high finance. My major is Economics with a math concentration (so I'll be taking classes such as multivariable calc, real analysis, etc.) but I would also like to double major in something else. I am debating between English or a Foreign Language (specifically Japanese). I really like both and am finding the decision to be a bit difficult so I was wondering which would be more useful from a high finance standpoint. One side of me leans towards English because of how it encourages one to build strong arguments and strong English skills are very important when it comes to high finance. But another side of me is leaning towards Japanese as I know of a few people who got summer internships at BBs due to being able to speak English and Japanese. I would love to be able to speak a second language and explore an amazing country to its fullest.
So do you guys have any input on this? Thanks!
