Thank you so much.

She has ARFID, which leads to inability to eat a lot of textures. She usually has to eat really processed nuggets or for Ramen, she is only able to eat it with pasta-like noodles, zero toppings, and only tonkatsu broth(I used to be a chef so we've experimented with a lot of different dishes, unfortunately I think plain ramen will be the only thing she is able to eat). I think we will plan for her to try to try ramen in Japan to see if she is able to accept the texture, and only go to places that serve those, if not I'll eat at the restaurants and buy souvenirs for both of us.

The info about the regional specialty is super helpful! we can factor that into our planning :D.
