[Famous Chichibu Soba Tachibana] is a soba restaurant in Chichibu City, Saitama Prefecture, that offers Nihachi soba made using underground water from Mount Buko. We are particular about “water,” which greatly influences the flavor of soba, and by using underground water nurtured by Chichibu's nature, we bring out the original flavor and strong texture of soba. The Japanese-style, relaxed interior is a space that is easy to use not only for lunch in between sightseeing, but also for those who want to enjoy a leisurely meal. It is also located within walking distance from Seibu-Chichibu Station, and is loved by a wide range of people, from locals to those visiting for sightseeing.
