Hello! I'm still finishing up an MA and planning to apply to PhD programs next season, so I hope you all don't mind me posting, but I am now really starting to think seriously about the process (though maybe a bit too early!). At the start of my MA my interest was primarily in early modern Japanese social history, but I've found myself increasingly dipping into the late medieval period. I feel this is going to prove to be a bit of a struggle, as I find that most of the early modern academics I'd be interested in working with (that aren't on retirement watch or teaching at strange places) deal with the late Tokugawa to Meiji periods. Right now the two programs that catch my eye the most are Yale and Harvard's programs. How important is it that your adviser lines up perfectly with your time period of interest?
