Ippin Kou Oyama
Founded 1975, Oyama's beloved shoyu ramen treasure for 50 years. The clear soy sauce broth, slow-simmered with chicken and pork, paired with irregular-thickness handmade noodles creates the 'Ippin Kou style' found nowhere else. TripAdvisor #1 restaurant in Oyama among 986 venues. Queues of 8+ groups form 40 minutes before opening. Jumbo gyoza with chewy thick skin packed with vegetables. A genuine institution beloved across generations. (Note: Ekiminami branch has closed. Joto branch continues operating.)

No sakura concerns (long-term accumulated reviews natural for a 50-year establishment).
