The best place to start when looking for employment or an internship is your own network of family, friends, etc. Think through your connections—there might be someone therein who works in the industry, or who knows somebody. It’s said that a majority of people find a job through someone they know. A friend who knows a friend who knows a friend that works in Tokyo, as far-fetched as it seems, could be the place to start. Get contacts in the area, tap your own social network (especially alumni resources from your college or university that will often favor fellow grads), and start asking questions. More often than not, this will lead you to that perfect summer engineering internship. Best of luck!
