Cross-posting from J-GAF thread:
Hey there J-GAF, hoping y'all can help me with a question about visiting your country. My wife and I are hoping to take a trip in about a year for three weeks or so. I've been studying Japanese pretty hard so I'm hoping to have some decent grasp of the language by then. In the meantime, I do have one concern. It's kind of a big one. My wife and I both get chronic migraines, and there are certain food triggers we have to avoid because they give us just absolutely awful migraines. Unfortunately, soy, including soy sauce and tofu and any form of soy, MSG, fish sauce, fermented foods like miso, dashi...those are some of the most significant migraine triggers.
Is it reasonable at all to be able to avoid these on vacation in Japan or is that going to be essentially impossible? (Ideally we would like to spend time in Tokyo, Fukuoka and Nara at the least.) Thanks in advance for any guidance you can offer.
BTW, I have no intention of going to a restaurant and asking for anything to be modified. My Japanese isn't good enough for that yet and honestly more importantly that's something I would almost never do here in the US, let alone in Japan where my understanding is in would be seen as especially rude.
(Alternately, how doable is a situation where we'd get our own kitchen and just...cook...most meals...like an AirBnB type deal? Hmm...I really want to make this work but I don't want us to contend with (worse) migraines (or any at all).)
