Bring water and Yamasa Ramen Broth Shoyu to a boil. Add egg noodles and cook for a few minutes. Drain and divide among 4 bowls.
Cut baby bok choy into halves, blanch for a few seconds in the broth, and distribute into the bowls.
Make swirls in the pot so the hot water creates swirls of motion, and immediately put in 16 wontons. Stir.
Let them cook until they float, and then continue cooking for 1 minute more. Scoop them out and distribute them evenly into the bowls. Pour the hot piping broth, top with chives and enjoy!
