A charcoal-grilled chicken specialist izakaya loved for 30+ years in Miyako-machi, Oita's largest nightlife district. The menu is admirably simple: only chicken thigh yaki, tataki (seared), and sashimi. The char-grilled local chicken is praised as 'by far the best local chicken I've ever eaten.' Showa-retro counter and tatami seating fill with regulars every night. Queues form before opening at 6pm; sashimi often sells out by 9:30pm. Tabelog 290 reviews, 3.58. Yahoo! Maps 4.21.
290 Tabelog reviews, 3.58. Yahoo! Maps 4.21. Tripadvisor 4.1 (within top 30 in Oita City). Long-time regular voices: 'I was shocked by how good the local chicken is', 'I've come here for 20+ years', 'I always stop here when in Miyako-machi.' Pre-opening queues and sashimi selling out early — genuine popularity. The three-item-only menu reflects the confidence of a local institution. No PR elements, no sakura indicators (long-established, cash only, evening only).
