Nankin Senryo Honke is a modest, family-run noodle shop credited by locals as one of the birthplaces of Kurume-style tonkotsu ramen, tracing its roots to a food stall that opened in 1937. The dining room has an eclectic, well-worn charm: reed-mat ceilings, wood-paneled walls hung with old photos and posters, ornate carved wooden chairs at lacquered tables, a tatami-style seating nook, and a compact counter facing the open kitchen. It draws ramen pilgrims curious to taste the style's origins alongside neighborhood regulars. The menu centers on the classic Kurume tonkotsu ramen, made with a "yobimodoshi" (continuously replenished) pork-bone broth, served alongside gyoza and simple rice dishes. The kitchen only operates for a short midday window, so arriving early is recommended.
