Stores open after security at Narita

I'll be taking an international flight from Narita to the US.
AFTER going through security, are there any convenience stores selling small snacks and meals?

I ask because during winter after I went through security at Chubu Airport in Aichi, all the convenience stores were CLOSED!!! I don't know if it was due to COVID or what, but nothing was open. The only thing we could by was drinks from the vending machine. It was insane!

Depends on time of day and terminal. Middle of the day and T1 or T2, should be an issue finding a shop open. Outside of these times, maybe not.

Food can go through security though, just not water. So you really dont have an issue anyway.

Thank you H! I'll be going in around 3-4 PM, so glad to know things should be open.

Strange question, but can baking soda go through security? I've recently been struggling with GERD, acid reflux, and heartburn. The medicine my doctor gave me is sooo weak, so I've been mixing a cup of water with baking soda. It'll be a 13+ hour flight and if I have issues, it's going to be hell. :(((

Dear help,

interesting question!

I have done a quick research due personel interest and found this:
