Nagai’s Hiroshima Okonomiyaki (Kuromon) is an okonomiyaki restaurant in Kuromon Market that cooks Hiroshima-style okonomiyaki. Okonomiyaki and yakisoba are served right at the teppan grill. It opened on March 1, 2026, and the owner takes orders alone by verbal or QR code. There are 4 counter seats inside and 2–3 counter seats outside, and one food order per person is required, so ordering only drinks is difficult.
