This snack is a rice-based treat infused with a wasabi flavor. It's possible that it goes by the name "Tora Senbei." The shop that sells this snack is called "Toranomon Kiya." Although they don't have an official website, you can find information about the shop on this website. https://tabelog.com/tokyo/A1308/A130802/13101621/
