Yeah, but I don't really want an office job translating document after document. I want to speak with other people. Like some sort of corperation that would call whenever they were having some sort of meeting with a foreign company. I could help them understand each other when they each speak. Anything like that out there?
If you go to a site like this one
, You can search for jobs in Japan based on your language levels (Japanese and English). If you read through the job postings and you can see what kind of stuff is available, what the job descriptions are, and what the requirements are.
Have you thought about sales or marketing? In the company I work for, our major customers are in the US, Korea, China, Taiwan, Singapore, Germany, and the Philippines (as well as Japan). All of those customers except the Japanese ones use English for business. Therefore, our sales and marketing teams must be fluent in English.
Those guys travel a lot, entertain customers, and use their Japanese and English skills to facilitate more technical meetings with other parts of the company (engineering, production, etc.). There are many companies in Japan that do business on a worldwide scale and at least in my field (semiconductors), English is the international language used.
You would probably have to shoot for something like an MBA along with fluency in Japanese to get a good marketing job. You also need to have the right people skills too.
