My long term career goal is to attend an English speaking medical school and become a physician. However, before doing so I wish to spend a few gap years in Japan. In all honesty, a primary reason is to rekindle a relationship that I had with a J-girl who studied abroad at my school (she wants to eventually live outside Japan herself).
Not to put a damper on things, and relationships are nice, but two things come to mind.
1) Rekindling. It just makes me wonder how serious you were initially, how long it's been since you separated and what both of you have done in the meantime. And, whether she even knows your plans for career and seeing her.
2) Does she really want to live outside Japan? Most Japanese don't, and the younger they are, the less fixed they are on it. Oh, she might have said something about it earlier (how long ago? what was the situation then? has it changed since?), but it might have been an idea like simply being enamored with a concept or a false vision of what it's like, instead of having a specific goal, something more solid to plan around.
The ideal scenario for me is to be granted both a Monbukagakusho scholarship and entrance to Tokyo University's International Health Master's program, which is conducted entirely in English.
When I lived in the U.S., it was already very difficult for anyone with a BS degree to go through a gap year and then get accepted to med school. Have you looked into how this gap will affect your chances? That applies whether you attend school or get a job in a related field here.
I have been looking towards contract research organizations, which I am qualified for degree and experience-wise. I found a few that were willing to sponsor overseas applicants. However, although many of these ads are written entirely English and do not specify a Japanese language requirement outright, I can't imagine that my role would entail no high level Japanese at all.
Try looking at daijjob.com or Career Cross web sites. To be honest, I really don't see much chance for a person with just a BS degree landing a job here in the sciences, especially with virtually no work experience beforehand. Been there.
I've tried to email recruiters for clarity on this but I have not heard back yet, maybe because of the holidays. Does there exist any organizations of this sort where the official workplace language is English, like Rakuten?
Darned few Japanese outfits. Foreign company branches are more likely.
I have also realized that I am qualified to work as a recruiting consultant in a pharmaceuticals/life sciences division.
Having worked in such fields for many years in the U.S., I have to find this pretty insulting. I've dealt with recruiters before, and most have no idea what the jobs in the field entail. They might know a tad of the lingo, but that's all. How have you determined you are "qualified"?
While the idea of doing recruiting doesn't exactly thrill me, I wonder if it will be more beneficial for my career or a better experience than teaching English. That said, I have heard a fair share of horror stories, so if anyone can shred some light on this I would greatly appreciate it.
I seriously doubt it.
I have just become fascinated with the country in general especially since learning some of the language. Though my Japanese is self taught, I was able to place into a fourth semester Japanese class at my university, of which I will take next semester.
TLDR: I want to spend a few gap years before medical school in Japan. I have basic conversation but not business level Japanese. Is there anything I can do in healthcare or science?
Already answered this more than once. The only other option I'd recommend is to look into unpaid internships.
