No Suta Honten
4 min walk from Shimo-Shinmei Station. No signboard, no noren curtain on the exterior whatsoever. Menus and opening times are announced only via the official X (Twitter) account — a truly eccentric operation. Three irregular rotations: thin noodles, Jiro-style, and limited specials. Tabelog 3.63.
"Worth following on X and checking the menu before visiting." "A mysterious shop with no sign or curtain, but the flavor is real." "The shio ramen's delicacy is top-tier in Tokyo." Feb 2026 visit confirmed.
