Recommended bowl: Extreme Bamboo Shoots

Open over 40 years, this shop serves local Kōrai-kei style ramen, which can be found served at roughly 30 or so shops in the region. Koyoken became famous for its menma ramen, which comes completely covered in a mound of thick-cut bamboo shoots. On the menu from the beginning, the soup recipe is derived from traditional Chinese natural ingredients, including onions, carrots, garlic, kombu, dried fish, chicken, pork bones, chinese chives and other ingredients that are said to contain aphrodisiac properties.The soup is cooked in a large stockpot for many hours. The housemade menma takes two days to make and marinates for much of that time. Open since 1976.
