Hakata Ramen Zen Ozasa is a ramen shop in Ozasa, Fukuoka, serving tonkotsu ramen, bean sprout ramen, and chashu ramen. The broth is light and slightly sweet, and you can adjust the flavor with garlic, sesame, and red pickled ginger. It opens at 10 a.m., and ordering at the ticket machine at the entrance brings your ramen in about a minute. If you are looking for a rich tonkotsu broth, this one is on the thin side.
