I really do not like replying on her behalf because that isn't my job, but she's asleep right now.
In Japan there is a heavy importance placed on learning English because in Japanese business there is 0% chance you will be able to go without speaking it. I think either her mother or both parents spoke English, so while raising her they'd teach her the language and often say "In English," to force her to recant what she just said in English.
I think she said she speaks: English, Spanish, and Japanese fluently, and is learning French. This pretty much grants her absolute job security as a translator. No further education required.
