I currently have about 14 months left of a PhD programme at a top-rated UK university. My project is in STEM and is partly sponsored by an industrial company. I recently went to a conference in Japan and presented my work. It was very well-received and I really enjoyed my experience in Japan, so much so that I didn't want to leave!
It turns out that my college offers a fully-funded "year in Japan" scheme for its students, which includes a combination of Japanese language classes and teaching English in elementary schools. Provided I am eligible, to me this sounds like it could appeal quite a lot - I am a mature PhD student in his thirties, so schemes like this aren't easily accessible to most people my age, and I've always had a slight itch to learn Japanese (but never had a strong enough reason to commit to it). I also get the impression that learning Japanese could be a handy skill to have, particularly as my scientific area involves collaboration with people all over the world.
However, as I am considering applying for postdocs once my degree finishes, I am slightly worried that having taken a year out of my formal scientific studies after my PhD might not look good. If I make a case for why I did the gap year (in this case, to learn the language and facilitate communication with other world experts), would it be seen as acceptable? Judging from other posts I have seen on the internet, certain postdoc programmes see any form of gap as a bit of a red flag. Having said that, I had a gap of several years working as an educator before I started my PhD, and this turned out not to be an issue when being selected.
What are your thoughts?
UPDATE: Based partly on the feedback I have since received, I have decided not to do this scheme. The scheme is only open to those who will have completed their PhD by the time the year abroad starts. Even with my originally planned end date, I would only have a month or so after submitting my PhD in which to complete my viva examination and make any revisions, before being eligible for the year abroad. Perhaps I could stick to visiting Japan every now and again for holidays.
