Sorry, I was not paying attention to gluten or nut allergies while in Japan. Neda is very lactose intolerant, and we know Japan is very good country to travel through for those suffering with that. Dairy products are not normally a part of any Asian diet. I don't recall seeing a lot of nuts in the foods we ate. Maybe in the desserts. Does sesame seed count? Lots of sesame seeds in Japanese cuisine, they also use a lot of sesame seed oil as well. Don't know if Japanese use peanut oil in their cooking. Might be something to research. As far as gluten, you'd think Japanese food would be safe since their staple is fish and rice. But there is wheat in the ramen and soba noodles, as well as the tempura, obviously. Also, the soy sauce they use will have wheat in them as well and they use that in everything. Hope this helps, and that you do find some nut/gluten-free Japanese cuisine. It really is our favorite food!
