In a medium-sized saucepan, combine the stock, soy sauce, and mirin and bring to a boil over high heat. Reduce the heat to a simmer and add the chicken and shiitake mushrooms. Simmer until chicken is cooked through, for 4-5 minutes.
Meanwhile, bring a medium-sized pot of water to a boil. Add the noodles and cook according to the package directions. Drain and split evenly among 4 bowls.
Add the hot broth, chicken, mushrooms, and spinach to each bowl. Add the sesame oil and garnish with scallions. Serve immediately.
